What are the main differences between the posterior and anterior pituitary glands in terms of their functions and hormone secretion?
The main differences between the posterior and anterior pituitary glands are in their functions and hormone secretion. The posterior pituitary mainly stores and releases hormones produced by the hypothalamus, such as oxytocin and vasopressin, while the anterior pituitary produces and releases its own hormones, including growth hormone, thyroid-stimulating hormone, and adrenocorticotropic hormone.

What is the function of the infundibulum?
The infundibulum is a funnel-shaped structure in the brain that connects the pituitary gland to the hypothalamus. Its function is to allow hormones produced by the hypothalamus to be transported and released into the pituitary gland for further regulation of hormone production and secretion.
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).
How is the anterior pituitary connected to the hypothalamus?
The anterior pituitary is connected to the hypothalamus through a network of blood vessels called the hypothalamic-hypophyseal portal system. This system allows hormones produced by the hypothalamus to be transported directly to the anterior pituitary where they can regulate the release of pituitary hormones into the bloodstream.
What are two ways the hypothalamus sends messages to the pituitary gland?
i releases hormones and controls body activities directly.
What is the name of the hormone that regulates milk secretion?
The hormone that regulates milk secretion is called prolactin. It is produced by the pituitary gland in response to the stimulation of the nipples during breastfeeding.
What part of brain controls the secretion hormone of posterior pituitary?
It is the hypothalamus. It controls the pituitary secretions
What stimulates adh secretion from the posterior pituitary?
ADH secretion is stimulated by factors such as dehydration, high blood osmolality, low blood pressure, and stress. These conditions trigger the hypothalamus to release ADH from the posterior pituitary gland to help regulate water balance in the body.
Is Oxytocin is secreted by the anterior lobe of the pituitary?
Oxytocin is secreted by the posterior pituitary and is peptide/water-soluble. It stimulates contractions during childbirth and milk secretion during nursing.
What is the process that controls the levels of the endocrine secretions called?
overall it would be negative feedbackthe hypothalamus controls the secretion of anterior and posterior pituitary hormones and the pituitary controls the secretion of many other glands. It's a complicated process with many different pathways.

What does the posterior pituitary gland control?
The posterior pituitary gland primarily releases hormones produced in the hypothalamus, such as oxytocin and vasopressin. These hormones play roles in regulating water balance, blood pressure, and uterine contractions during childbirth.
What is the function of the infundibulum?
The infundibulum is a funnel-shaped structure in the brain that connects the pituitary gland to the hypothalamus. Its function is to allow hormones produced by the hypothalamus to be transported and released into the pituitary gland for further regulation of hormone production and secretion.
Is the secretion of pituitary hormones largely controlled by the thalamus?
No, the secretion of pituitary hormones is largely controlled by the hypothalamus. The hypothalamus produces releasing and inhibiting hormones that regulate the secretion of hormones from the pituitary gland. The thalamus is primarily involved in relaying sensory information to the cerebral cortex.
Which control the secretion of pituitary gland?
Hypothalamus
What controls the secretion of growth hormone?
The pituitary gland controls the secretion of growth hormone.
What has the author Archibald Ross McIntyre written?
Archibald Ross McIntyre has written: 'The mechanism of the action of extract of the posterior lobe of the pituitary body on the secretion of urine in the unanaesthetized dog' -- subject(s): Physiological effect, Pituitary extract, Urination, Dogs, Physiology 'Curare' -- subject(s): Curare
What is somatostanin?
Somatostatin is a hormone produced in the pancreas and other parts of the body that regulates various physiological functions, including the inhibition of growth hormone secretion from the pituitary gland and the inhibition of gastric acid secretion in the stomach. It also plays a role in regulating insulin and glucagon secretion from the pancreas.
