The hypothalamo-hypophyseal neurosecretory system of the parakeet, Melopsittacus undulatus
General and Comparative Endocrinology, 1961Abstract The hypothalamo-hypophyseal neurosecretory system of the parakeet, Melopsittacus undulatus, was studied with both light and electron microscopes. The neurosecretory centers consist of paired supraoptic nuclei and paraventricular nuclei. Each nucleus is divisible into medial and lateral cell groups. The neurosecretory axonal tracts arising in

The hypothalamo-hypophyseal neurosecretory system of Gegenophis carnosus Beddome [PDF]
Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1957 1. The brain of Gegenophis carnosus Beddome resembles that of Ichthyophis glutinosus in general organisation. In size, shape and structure the hypophysis of Gegenophis differs from that of other groups of Amphibians. The pars nervosa is at the posterior tip of the hypophysis and is connected to the brain by a nervous tract. 2.

Coexistence of salusin and vasopressin in the rat hypothalamo-hypophyseal system
Neuroscience Letters, 2005Salusins are two newly discovered TOR-related peptides consisting of 28 and 20 amino acids and designated salusin-alpha and salusin-beta, respectively. Using immunohistochemistry techniques, salusin-like immunoreactivity was detected in the rat hypothalamo-neurohypophyseal tract and immunopositive cells were distributed in the suprachiasmatic ...

Chemical Neuroanatomy of the Hypothalamo-Hypophyseal System in Sturgeons
2017The preoptic-hypothalamo-hypophyseal system of sturgeons, located at the base of the brain, has a neurosecretory role exerted by hypophysiotropic neurons most of them located in the preoptic and hypothalamic periventricular region. The majority of those cells are of the cerebrospinal fluid-contacting type and exhibit short processes reaching the ...

Hypothalamo-hypophyseal neurosecretory system inRana temporaria in early ontogenesis [PDF]
Neuroscience and Behavioral Physiology, 1972 The hypothalamo-hypophyseal neurosecretory system (HHNS) was investigated in tadpoles and immature frogs of the speciesRana temporaria. Heterochronia was established in the formation of the preoptic nucleus (earlier differentiation of neurosecretory cells in the dorsal than in the ventral part).

The effect of su-4885 on the hypothalamo-hypophyseal neurosecretory system of the rat
Acta Neurovegetativa, 1964The effect of Su-4885 on the hypothalamo-hypophyseal neurosecretory system of the rat was studied by histological means. No changes in the amount of the neurosecretory material or in the activity of the neurosecretory ganglion cells could be observed.

Neurosecretion in the hibernating bat. The morphology of the hypothalamo‐hypophyseal system
The Anatomical Record, 1965AbstractThe morphology of the hypothalamo‐hypophyseal tract of 35 hibernating bats (Myotis lucifugus lucifugus) was studied in chrome‐alum‐hematoxylin‐phloxine‐stained serial coronal and sagittal sections. Vinyl acetate and wax‐plate reconstructions also aided in describing the two neurosecretory hypothalamic nuclei of this system. The most prominently

Monoamine?Containing structures in the hypothalamo-hypophyseal system in the human fetus
Zeitschrift f�r Anatomie und Entwicklungsgeschichte, 1973The monoamine containing structures of the human fetal hypothalamohypophyseal tract were studied histochemically by demonstrating the formaldehyde induced fluorescence. First specific fluorescence in the hypothalamus and median eminence was observed at the age of 15 weeks.

On a examine la reactivite osmotique du systeme antidiuretique hypothalamo-hypophysaire et du mecanisme de la soif chez des chiens non narcotises. Chez tous les animaux examines, le systeme antidiuretique s'est montre plus sensible aux stimulus osmotiques que le mecanisme de la soif.

Effects of Indomethacin on the Hypothalamo-Hypophyseal Neurosecretory System
1978Four groups of animals were investigated: intact rats, waterdeprived rats, rats given indomethacin, and rats initially given indomethacin and then transferred to water-deprived conditions while continuing to receive indomethacin. Some animals were investigated 3 days after being water deprived.
