What do Pituicytes do?
What do Pituicytes do?
Pituicytes are similar to astrocytes, another type of glial cell. Their main role is to assist in the storage and release of hormones of the posterior pituitary. Pituicytes surround axonal endings and regulate hormone secretion by releasing their processes from these endings.
What does peptide oxytocin do?
Oxytocin (Oxt or OT) is a peptide hormone and neuropeptide normally produced in the hypothalamus and released by the posterior pituitary. It plays a role in social bonding, reproduction, childbirth, and the period after childbirth.
What do Neurohypophysial hormones do?
The neurohypophyseal hormone AVP has multiple actions, including the inhibition of diuresis, contraction of smooth muscle, aggregation of platelets, stimulation of liver glycogenolysis, modulation of adrenocorticotropic hormone release from the pituitary, and central regulation of somatic functions (thermoregulation …
What stimulates the release of endogenous oxytocin?
Oxytocin is released in response to activation of sensory nerves during labor, breastfeeding and sexual activity. In addition oxytocin is released in response to low intensity stimulation of the skin, e.g., in response to touch, stroking, warm temperature, etc.
Is there an oxytocin supplement?
In clinical trials, oxytocin shows promise as a treatment for obesity and may have other off-label uses. It’s a naturally occurring hormone that’s also available as a supplement. Taking oxytocin doesn’t create a high, but it may make you feel happier and more socially connected.
Does oxytocin increase estrogen?
Estrogen can actually increase the amount of oxytocin there is available by activating the cells that make oxytocin. Estrogen could also increase the number of those oxytocin receptors on the trigeminal nerve. What happens if you drop your estrogen, you also drop your oxytocin because estrogen drives oxytocin.
What organs are the main targets for oxytocin?
| Endocrine gland/ source of hormone | Hormone | Target organ or tissue |
|---|---|---|
| Anterior pituitary (adenohypophysis) | Prolactin | Mammary gland |
| Posterior pituitary (neurohypophysis) | ADH (antidiuretic hormone) | Kidney tubules Smooth muscle in arterioles |
| Oxytocin | Uterine smooth muscle Mammary gland | |
| Pineal gland | Melatonin | Various tissues |
Where is oxytocin produced?
Oxytocin is produced mainly in the hypothalamus, where it is either released into the blood via the pituitary gland, or to other parts of the brain and spinal cord, where it binds to oxytocin receptors to influence behavior and physiology.

What will happen to Rathke’s pouch?
The hypophysis is an amalgam of two tissues. Early in gestation a finger of ectoderm grows upward from the roof of the mouth. This protrusion is called Rathke’s pouch and will develop into the anterior pituitary or adenohypophysis.
