The posterior pituitary gland, also known as the neurohypophysis, shares a name with the anterior pituitary but has indirect connection to the brain as the posterior pituitary contains the nerve endings of the vasopressin and oxytocin neurons which originate in the periventricular and supraoptic nuclei...

Step-by-Step Solution:1. Definition of Endocrine Glands: Endocrine glands are known as ductless glands. They produce hormones and release them directly into the bloodstream without the use of ducts.2.
aThe posterior lobe of the pituitary gland has an abundant nerve supply. Nerve cell bodies in the posterior lobe produce two neurosecretions(antidiuretic hormone [ADH] and oxytocin), which are stored as granules at the site of the nerve cell bodies. When the hypothalamus detects a need for tit...

What is another name for the pituitary gland? What does the posterior pituitary gland do? What controls hormone release from the anterior pituitary gland? What hormones does the anterior pituitary gland secrete? What hormones are secreted by the posterior pituitary gland?
the posterior pituitary gland. Other hormones, such as releasing and inhibiting hormones, are secreted into the blood to stimulate or inhibit hormone production in the anterior pituitary gland.

It has been suggested by Rennels and Drager 2 that the parenchymatous glandular cells may play a part in the final release of the hormones of the posterior pituitary into the general circulation. Although Gray 3 described mast cells in the pituitary gland of man, ox and cat, the presence ...
PITUITARY BODY/physiologyTHE acetone extract from posterior pituitary lobes of cattle includes a number of substances of special interest. One of these substances decreases the growth-rate of young animals, plant seedlings and transplantable mouse carcinoma. Another substance when injected into white mice...
5.Function of the Connection: The posterior lobe of the pituitary gland stores and releases hormones that are produced in the hypothalamus, such as oxytocin and vasopressin (antidiuretic hormone). When needed, these hormones are released into the bloodstream from the posterior lobe. ...
