Degeneration and regeneration of neurosecretory systems.

International Review of Cytology, 1973
Publisher Summary Degenerative and regenerative phenomena have substantially contributed to the knowledge of neurosecretory systems. The general structural organization, the degeneration, and regeneration of neurosecretory neurons, and the process of neurosecretion are identical throughout the animal kingdom.

Neurosecretory systems in decapod Crustacea

Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 2004
The sinus glands of the Brachyura are composed of swollen nerve fiber endings, which store and release secretory material synthesized within cells of the eyestalks, the brain and probably the thoracic ganglionic mass. Removal of the sinus glands from the land crab, Gecarcinus lateralis, does not induce molt, because sinus glands are reservoirs, not ...

Cellular dynamics in invertebrate neurosecretory systems.

International Review of Cytology, 1977
Publisher Summary This chapter discusses the cellular dynamics in invertebrate neurosecretory systems. The chromatographic and electrophoretic microtechniques provide complete information on the range of active factors and their distribution in individual species.

The caudal neurosecretory system of fishes

General and Comparative Endocrinology, 1962
Abstract The comparative microanatomy, cytology, and ultrastructure of the caudal neurosecretory system of teleost fishes are surveyed, and some of the variations in morphologic features of the urohypophysis are indicated, based on the study of 125 teleost species. The neurohemal organ, the urohypophysis, was present in every teleost specimen studied.

Brain stem innervation of the caudal neurosecretory system

Cell and Tissue Research, 1982
The innervation of the caudal neurosecretory system of Poecilia sphenops (black molly) was studied by use of the retrograde horseradish peroxidase (HRP) method. The structure of the caudal neurosecretory system in this species was well suited for application of HRP procedures.

Nervous, sensory, and neurosecretory systems

1992
Abstract The sensory receptors and organs, and neurosecretory system of millipedes are among the better-studied areas of myriapod biology. These topics are covered in detail in this chapter in Sections 6.2 and 6.3. However, apart from anatomical descriptions (e.g.

The caudal neurosecretory system in some elasmobranchs

General and Comparative Endocrinology, 1962
A caudal neurosecretory system is found to be present in the elasmobranch species investigated. The secretion is transported along the neurosecretory processes to the peripheral area of the spinal cord, where the processes connect up with meningeal vessels.

The caudal neurosecretory system

Cell and Tissue Research, 1976
Recent information on the caudal neurosecretory system (urophysis) is collated, with special reference to cellular biology including neural relations, activity and chemistry 8 the biological principles associated with the urophysis, pharmacological analysis of the receptors for these principles, and their possible functions in a physiological sense ...

Adrenalectomy increases sprouting in a peptidergic neurosecretory system

Neuroscience, 1982
The neurons of the paraventricular nucleus of the hypothalamus have a substantial vasopressin-containing projection to the zona externa of the median eminence. Several parameters of neuronal function are increased in these cells following adrenalectomy; these increases can be prevented by glucocorticoid treatment.
