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 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 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.
In males what hormone is repsonsible for promoting the secretion of testosterone?
The luteinizing hormone (LH) is responsible for promoting the secretion of testosterone in males. LH is released from the pituitary gland and stimulates the Leydig cells in the testes to produce testosterone.
In what sense does the pituitary take orders from the target organs under its command?
The pituitary gland receives feedback signals from the target organs it influences through hormones. These signals help regulate the pituitary's secretion of hormones to maintain balance in the body. Thus, the pituitary takes orders indirectly by responding to the needs of the target organs.
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.
Which control the secretion of pituitary gland?
Hypothalamus
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.
What controls the secretion of growth hormone?
The pituitary gland controls the secretion of growth hormone.
What part of brain controls the secretion hormone of posterior pituitary?
It is the hypothalamus. It controls the pituitary secretions
What gland stimulates growth and secretion of the thyroid gland?
Pituitary
What regulates growth through secretion of growth hormone?
Secretion of growth hormone (GH) in the pituitary is regulated by the neurosecretory nuclei of the hypothalamus.
What is the gland that stimulates growth and secretion of hormone from other glands is what?
The Pituitary Gland.
What are the factors that regulate MSH secretion?
Melanophore stimulating hormone (MSH) secretion from the vertebrate is regulated by the hypothalamus. Removal of the pituitary from control results in an autonomous uninhibited secretion of MSH.
Exert negative feedback on the anterior pituitary relative to fsh secretion?
Estrogen and progesterone.
What hormones affect the secretion of other endocrine glands?
Pituitary gland
Breast feeding is thought to inhibit ovulation by directly?
inhibiting the secretion of GnRH
