Abstract
The caudal neurosecretory system is described here for the first time in the zebrafish, one of the most important models used to study biological processes. Light- and electron-microscopical approaches have been employed to describe the structural organization of Dahlgren cells and the urophysis, together with the immunohistochemical localization of urotensin I and II (UI and UII) peptides. Two latero-ventral bands of neuronal perikarya in the caudal spinal cord project axons to the urophysis. The largest secretory neurons (approximately 20 microm) are located rostrally. UII-immunoreactive perikarya are much more numerous than those immunoreactive for UI. A few neurons are immunopositive for both peptides. Axons contain 75-nm to 180-nm dense-core vesicles comprising two populations distributed in two axonal types (A and B). Large dense vesicles predominate in type A axons and smaller ones in type B. Immunogold double-labelling has revealed that some fibres contain both UI and UII, sometimes even within the same neurosecretory granule. UII is apparently the major peptide present and predominates in type A axons, with UI predominating in type B. A surprising finding, not previously reported in other fish, is the presence of dense-core vesicles, similar to those in neurons, in astrocytes including their end-feet around capillaries. Secretory type vesicles are also evident in ependymocytes and cerebrospinal-fluid-contacting neurons in the terminal spinal cord. Thus, in addition to the urophysis, this region may possess further secretory systems whose products and associated targets remain to be established. These results provide the basis for further experimental, genetic and developmental studies of the urophysial system in the zebrafish.

Abstract
Results obtained by examining hypothalamic neurons producing precursors to neurohormones, and pituitary cells synthesizing peptide and glycoprotein families of hormones, and recent advances in comparative endocrinology, have been summarized and considered from the following viewpoints: species specificity in the organization and communication of the hypothalamic neurons with different brain areas lying inside the BBB and with CVOs; sensitivity of hypothalamic neurons and pituitary cells to the environmental stimuli; gonadal steroids as modulators of gene expression needed for neuronal differentiation and synaptogenesis; dose(s)-dependent pituitary cell proliferation and differentiation; an inverse relationship between PRL and GH synthesis and release and also between degree of hyperplasia and hypertrophy of PRL cells and retardation of GTH cell differentiation; and responsiveness of neurons producing CRH, and of neurons and pituitary cells synthesizing POMC hormones, to stress and glucocorticosteroids. These data show that growth of the animals may be stimulated, retarded, or inhibited; reproductive properties and behavior may be under hormonal control; and character of responsiveness in reaction to stress, and ability for adaptation and other related functions, may be controlled.

Abstract
We have determined the distribution and localization of the monoamine octopamine in the prosomal central nervous system of the horseshoe crab, Limulus polyphemus, by light and electron microscopic immunocytochemistry. Sixteen discrete clusters of octopamine-like immunoreactive neurons are situated bilaterally in the tritocerebrum and circumesophageal ring of fused thoracic ganglia. Two pairs of anterior clusters are located laterally in the cheliceral and first pedal ganglia; the remaining six pairs of clusters are located ventromedially in the second through fifth pedal ganglia, chilarial ganglia, and opercular ganglia. The immunoreactive somata range from about 40 to 100 microns in diameter and occur in clusters of 12-24 cells. There is extensive distribution of octopamine-immunoreactive nerve fibers in Limulus; dense fiber tracts course anteroposteriorly through the central nervous system, and most neuropil regions are innervated by immunoreactive processes and terminals. This wide distribution of octopamine-like immunoreactivity provides an anatomical basis for the several effects of octopamine in Limulus. We determined the subcellular localization of octopamine by postembedding immunoelectron microscopy. The immunogold-labelled terminals are morphologically unique; they contain large, distinctively shaped dense-core granules, typically cylindrical with a prominent indentation in one end. These large granules are 100-150 nm in diameter and range from 150-400 nm in length. The dense labelling of these unusual granules with immunogold particles indicates that octopamine is sequestered in or associated with the granules.

Abstract
The cerebral origins and axonal trajectories of neurons projecting to the retrocerebral complex of the cricket, Teleogryllus commodus, were examined in silver-intensified nickel preparations. Spatially separate groups of somata in the pars intercerebralis (PI) and in the pars lateralis (PL), commonly accepted as neurosecretory loci, were found to give rise to axons which terminate in the nervus corporis allati 2, the corpus allatum, or the corpus cardiacum. Additional findings demonstrated a distinct group of somata from the PI whose axons run in the esophageal nerve (stomatogastric nervous system), nine somata in the subesophageal ganglion with axons projecting into the nervus corporis allati 2, and also a small cluster of tritocerebral perikarya with axons terminating in the corpus cardiacum. Somata residing in the PI and PL were found to be compartmentally organized based upon the retrocerebral destinations of their axons. Possible functional consequences of these results with respect to the insect neurosecretory system are discussed.

Abstract
Neurosecretory cells in the mollusc Helix have perikarya that show clear signs of adaptation for both the synthesis and the discharge of secretory material. They are characterized morphologically by juxtaposition with the neural lamella. Passage of hormone into the haemocoel is apparently facilitated in many cases by the extreme attenuation of areas of the lamella and perineurium adjacent to the perikarya and by other forms of histological differentiation. Presumptive sites of release are characterized by prominent aggregations of synaptoid vesicles and the discharge of the contents of secretory granules by exocytosis.

Abstract
A comparative ultrastructural study of insects was made whose primitive perisympathetic organs consisted either of a single median neurohemal formation per segment (Periplaneta americana) or of two transverse formations (Carausius morosus), or again, of three--one median and two transverse--as in Locusta migratoria. The results showed that the perisympathetic organs always comprised two types of structure (alpha and beta), even when a single formation exists. In Periplaneta and Carausius, both types were seen to coexist in the same neurohemal formation. In Locusta, however, they were separated, the alpha structure constituting the median organ and the beta structure, the two transverse organs. Each of the two structures have special features: the beta structure displays the usual characteristics of a loose neurohemal organ, i.e., it is penetrated by sinuses and has neurosecretory endings devoid of a glial coat; the alpha structure, on the contrary, forms dense compact organs whose endings are covered with a continuous glial layer. During the evolution, this last structure gradually separated from the other neurohemal formations. It was observed to correspond to a single type of neurosecretory cell, distinct from all other cell types by the particular mode of its release. These results for primitive perisympathetic organs confirm earlier findings for advanced organs. They indicate that both the alpha and beta structures are generally present in insects, thus showing their importance in the physiology of these animals.

Abstract
Topographical relationships of neurosecretory axons with the capillaries of the primary portal plexus were studied in the median eminence of rats from the 14th fetal till the 9th postnatal day by means of electron microscopy combined with morphometric analysis. Special attention was given to the light and electron microscopic immunocytochemical examination of luteinizing hormone-releasing hormone projections to the median eminence. Neurosecretory axons possessing secretory granules and clear microvesicles were first observed in the median eminence at the 14th fetal day. However, all of them were situated at a distance from the primary portal plexus. By the 20th fetal day, neurosecretory axons reached the external basal lamina of the primary portal plexus giving rise to so-called axovascular contacts. Some axons even penetrated into the perivascular space, apparently facilitating the neurohormone delivery into the hypophysial portal circulation. From that time on, both the number of the axons abutting on the external basal lamina and the entire area of axovascular contacts increased gradually. As to luteinizing hormone-releasing hormone axons, they grew into the median eminence from the 18th fetal day concentrating in older fetuses and neonates either over the primary portal plexus, or around the infundibular recess of the 3rd ventricle. After birth, the concentration and distribution of luteinizing hormone-releasing hormone axons within the median eminence became similar to those of adults. Luteinizing hormone-releasing hormone axons were found to arise from the neurons of septopreoptic area including the diagonal band of Broca. These data suggest the onset of neurohormone release in the median eminence from the 14th fetal day followed by the establishment of the hypothalamic control over the pituitary functions during the perinatal period in rats.

Abstract
The structure and electrophysiological properties of individual neurosecretory cells of the pars intercerebralis, medial neurosecretory cells (MNSCs), in the brain of an insect, the cricket Teleogryllus commodus, were investigated by means of intracellular injections of the dye Lucifer Yellow and electrophysiological recordings. Action potentials recorded from these cells were of long duration, 8-50 msec. In the pars intercerebralis there are both neurosecretory cells with axons that join one of the tracts of the nervi corpori cardiaci I (NCC I) and cells without an axon or collateral that leaves the brain, local neurosecretory cells. MNSCs with axons that join NCC I and terminate in the anterior corpus cardiacum arborize extensively in the protocerebrum and to a lesser degree in the deutocerebrum. Other MNSCs have axons that pass through the corpus cardiacum and hypocerebral ganglion and join one of the oesophageal nerves. These MNSCs have sparse collateral arborizations in the protocerebrum but do have extensive terminal arborizations in the tritocerebrum. This type of cell is dye-coupled to other MNSCs. Among the local MNSCs, some have an unusual loop shape. These cells branch extensively in the protocerebrum and have massive terminal arborizations in a posterior ventromedial region of the brain. Both the long curved axons of the loop-shaped cells and their ventromedial branches are of large diameter, suitable for storage of neurosecretory material.

Abstract
Ultrastructural comparison of different types of perisympathetic organs (POs) in three species of Coleoptera (Chrysocarabus auronitens, Oryctes rhinoceros, and Tenebrio molitor) showed that the structure of these organs was not related to their morphological types but to their topography. Two kinds of PO structure may be distinguished: compact median and diffuse lateral. They were similar in that both were surrounded by thin neural lamellae and exhibited numerous glial cells originating in the perineurium (type I perineurial cells) as well as abundant neurosecretory endings. They were different in as much as in median POs, the neurosecretory endings were generally surrounded by perineurial processes but in transverse POs, these endings were sheathless. Only one type of neurosecretory axon was distinguished in the median organs but three or four in the transverse. The nature of the processes by which neurosecretory granules are released may depend on the type of neurosecretory axon. For instance, exocytosis always occurred for dense spherical granules, and granule fragmentation was visualized for granules of smaller size.

Abstract
A fine structural study has been made of the 'paraganglionic plates' associated with the perineurium and of the 'retrocerebral organ' associated with the periganglionic sheath of the tick Boophilus microplus; these structures have been postulated, from descriptions by light microscopy, to be tick neurohaemal organs. Neurosecretory terminals are observed frequently in the neural lamella/perineurial sheath, particularly in a dorso-lateral area which may correspond to the 'paraganglionic plates'. No evidence was found of a discrete peripheral neurohaemal organ such as the corpus cardiacum of insects. The 'retrocerebral organ' is comprised of periganglionic sheath cells, which appear to be glandular rather than neurohaemal, and peripheral ganglionic cells.

Abstract
Definitive evidence is presented to show that arthropod neurohaemal terminals contain electron-dense T-bar structures with clustered microvesicles similar to those present in neuropilar and neuromuscular terminals. In terminal membranes of the locus corpus cardiacum, studied by freeze-fracture, intramembranous particle arrays, considered to correlate with the dense bars, are seen. However, there does not appear to be a spatial association between the arrays and the exocytotic profiles seen following exposure to stimulants for hormone release. The presence of the densities in both neuroendocrine and conventional terminals is discussed in the light of current theories for mechanisms of release of neurotransmitters and neurohormones in arthropods and vertebrates.

Abstract
The two bilateral clusters of neurosecretory bag cells of Aplysia were studied with both light and electron microscopy. Autoradiography revealed that the bag cells rapidly accumulate 3H-labelled amino acids and that after 1-2 h, heavy concentrations of silver grains appear over Golgi complexes and in the proximal axons. Intrasomatic injections of CoCl2 or lucifer yellow showed clear branch points and numerous varicosities along individual axons. Many of the bag cells are multipolar. Electron-microscopic observations confirmed that individual fibres branch and showed that the varicosities are packed with dense-cored vesicles similar in size (180 nm diameter) and electron density to those found in the somata. The axons of several cells are usually associated into bundles that travel (within the connective tissue sheath) either rostrally up the pleurovisceral connective or toward the contralateral bag cell cluster. Bundled in groups of tens to hundreds, a total of many thousands of axons fill the sheath around each cell cluster and around the proximal 2-5 mm of the pleurovisceral connective; the number of axon bundles in the sheath decreases rapidly with distance from the cluster. Individual axons reaching the outer edges of bundles from neurosecretory endings near blood sinuses in the sheath, creating an extensive neurohemal release area. Dense-cored vesicles are packed into the endings, often in very close apposition to the plasma membrane. Possible release profiles (omega-shaped) and smaller clear vesicles (85 nm diameter) were observed in the axon endings. A number of axons also enter and travel among the conventional (non-neurosecretory) axons in the core of the pleurovisceral connective nerve. These 'core' bag cell axons project for several millimetres beyond the terminations of the bundled axons of the sheath. The findings support the hypothesis proposed in physiological studies that the distribution and branching of the axonal tree are the basis for the extracellularly recorded wave forms and of the potentiation of electrical signals during bag-cell activity. Additional evidence indicates that exocytosis is the means by which bag-cell hormone is released during afterdischarges.

Abstract
Morphological indications and new experimental results demonstrate that neurosecretory peptides or low-molecular proteins, respectively, appear to effect as mediators in information transmission. They are acting as releasers triggering specific behavior programs in the nervous system or as modulators in the regulation of different functions. This can be observed in different groups of the animal kingdom including mammals and man as well as different levels of organization or systems. Some of such facts at behavior level, concerning regulation of organ function and finally at cellular level of distinct single neurons are discussed.
