The posterior pituitary (or neurohypophysis) is the posterior lobe of the pituitary gland which is part of the endocrine system. The posterior pituitary is not glandular as is the anterior pituitary.

2023年8月23日 · The neurohypophysis is divided into two regions; the pars nervosa and the infundibular stalk. Sometimes the pars intermedia and the median eminence are included. It secretes oxytocin and vasopressin; vasopressin is also called antidiuretic hormone (ADH) due to its function of preventing diuresis.

2022年11月9日 · The neurohypophysis is the structural foundation of a neuro-humoral system coordinating fluid balance and reproductive function through the action of two peptide hormones: vasopressin and oxytocin. Vasopressin is the principle endocrine regulator of renal water excretion, facilitating adaptive physiological responses to maintain plasma volume ...

2023年8月23日 · The neurohypophysis is divided into two regions; the pars nervosa and the infundibular stalk. Sometimes the pars intermedia and the median eminence are included. It secretes oxytocin and vasopressin; vasopressin is also called antidiuretic hormone (ADH) due to its function of preventing diuresis.

2023年10月30日 · The neurohypophysis forms the posterior portion of the pituitary gland (hypophysis). It contains the posterior lobe of the pituitary gland and differs in both structure and function to its anterior counterpart, the adenohypophysis .

2023年4月11日 · Vasopressin is also known as the antidiuretic hormone (ADH). ADH helps regulate your body’s water balance by making your kidneys conserve more water. It also helps maintain blood pressure...

In response to high blood osmolarity, which can occur during dehydration or following a very salty meal, stimulation of osmoreceptors causes neurons in the supraoptic nucleus to signal the posterior pituitary to release antidiuretic hormone (ADH). The target cells of ADH are located in the tubular cells of the kidneys.

2019年2月27日 · The posterior lobe of the pituitary, also known as the neurohypophysis, secretes oxytocin and anti-diuretic hormone (ADH), also known as vasopressin. Both of these peptides are produced in the hypothalamus, pass through nerve fibers in the hypothalamo-hypophyseal tract, and are released from the pars nervosa (posterior lobe) in response to ...

2023年8月31日 · Antidiuretic Hormone (ADH) Release: The neurohypophysis releases ADH, also known as vasopressin, in response to changes in blood osmolality and blood volume. ADH acts on the kidneys to increase water reabsorption, reducing urine output and helping to maintain fluid balance and blood pressure.

2024年4月24日 · Even synthesized in the hypothalamus, the hormone is transported to the neurohypophysis (posterior pituitary gland) through nerve cells which are then released into the bloodstream through neurohypophysial capillaries by the process of exocytosis involving calcium. ADH is called vasopressin due to its vasopressor response to pharmacological doses.
