Neurosecretary cells respond to neural control. When they are stimulated they release inhibiting hormones, as well as others. The pituitary gland produces and releases human growth hormone (hGH). In order to control the amount of hormone released, the endocrine system has a hormonal control system, neural control system, and a negative and positive feedback system. If the hypothalamus decides that the pituitary is putting out too much hGH, it uses neural control via the neurosecretory cells to release human growth hormone inhibiting factor (hGHIF) through hormonal control slows down the production in the pituitary.

How doesHypothalamus controls secretions in the adenohypophysis by?
The hypothalamus controls secretions in the adenohypophysis (anterior pituitary) through the release of specific hormones known as releasing and inhibiting hormones. These hormones travel through the hypothalamic-hypophyseal portal system to the anterior pituitary, where they stimulate or inhibit the secretion of various pituitary hormones. For example, thyrotropin-releasing hormone (TRH) promotes the release of thyroid-stimulating hormone (TSH), while somatostatin inhibits growth hormone secretion. This regulatory mechanism ensures that the anterior pituitary responds appropriately to the body's needs.
What does somastotatin do?
Somatostatin: inhibits insulin & glucagon secretion by the pancreas. Inhibits TSH, GH, and ACTH secretion by adenohypophysis.
How do sympathetic and parasymphatetic activity affect gastric secretion?
Sympathetic activity inhibits gastric secretion by causing vasoconstriction of blood vessels in the stomach lining. Parasympathetic activity stimulates gastric secretion by increasing blood flow and activating gastric glands, leading to increased production of stomach acid and digestive enzymes.
What is the effect of alcohol to antidiuretic hormone secretion?
Alcohol inhibits the release of antidiuretic hormone (ADH) from the pituitary gland, leading to increased urine production and dehydration. This can contribute to the diuretic effect of alcohol and can lead to increased frequency of urination and potentially disrupt the body's water balance.
What inhibits the antidiuretic hormone?
The secretion of antidiuretic hormone is inhibited by both alcohol and caffeine. I'm trying to learn at what level (pituitary, where the actual secretion occurs) or the hypothalamus where ADH (vasopressin) is produced.
How can FSH be the cause of not producing eggs?
FSH, secreted by the Pituitary gland,stimulates the secretion of Oestrogen from the ovaries, Oestrogen in turn stimulates the secretion of LH by the pituitary and inhibits the secretion of FSH, LH then stimulates ovulation (the release of an egg). Without FSH this chain reaction does not happen.
What structure controls secretion of hormones from the anterior pituiary gland?
The brain controls the secretion of digestive enzymes. The brain tells your body when there is food that needs to be digested.
What hormones inhibits secretion of follicle stimulating hormone by the anterior pituitary?
inhibin and estrogen in females, inhibin and testosterone in males
What hormones control the secretion of FSH?
Follicle-stimulating hormone (FSH) secretion is primarily regulated by gonadotropin-releasing hormone (GnRH) from the hypothalamus. GnRH stimulates the release of FSH from the anterior pituitary gland. Additionally, negative feedback from sex steroids such as estrogen and testosterone can also influence FSH secretion.
Which is not a function of the hypothalamus?
The hypothalamus stimulates or inhibits secretion of hormones by the pituitary gland. One of these is GH or Growth Hormone.

Yes or no -Is thyroxine inhibits the secretion of TSH by the anterior gland which maintains homeostasis?
true
Is ADH inhibited by alcohol or increases urine production or promotes dehydration or is produced in the adenohypophysis?
Alcohol inhibits antidiuretic hormone (ADH) secretion, leading to increased urine production and promoting dehydration. ADH is produced in the hypothalamus and stored in the posterior pituitary gland, not the adenohypophysis (anterior pituitary gland).
What hormone stimulates and inhibits production of hormones by the pituitary gland?
The hypothalamus produces corticotropin-releasing hormone (CRH) to stimulate the pituitary gland to release adrenocorticotropic hormone (ACTH) and growth hormone-releasing hormone (GHRH) to stimulate the production of hormones. On the other hand, somatostatin inhibits the release of growth hormone and dopamine inhibits the release of prolactin from the pituitary gland.
What is the of secretin?
It inhibits the secretions of the stomach.
What does somastotatin do?
Somatostatin: inhibits insulin & glucagon secretion by the pancreas. Inhibits TSH, GH, and ACTH secretion by adenohypophysis.
What does fsh Lh and oestrogen do?
FSH-Follicle-Stimulating Hormone1-secreted by pituitary gland.2-Causes eggs to mature in ovaries.3-Stimulates ovaries to produce oestrogen.Oestrogen1-secreted by ovaries.2-Inhibits (slows down) FSH production.3-Stimulates pituitary gland to produce LH.4-Stimulates uterus lining to build up, ready to support a developing baby.LH-Luteinizing Hormone1-Stimulates ovaries to release eggs.
