secrete Adrenocorticotropic Hormone and Melanocyte Stimulating Hormone (anterior pituitary)
Within target cells increases synthesis of insulin-like growth factors that act locally or enter bloodstream
Insulin-like growth factors: -Increase cell growth and cell division by increasing the uptake of amino acids and synthesis of protein
-Stimulate lipolysis in adipose tissue so fatty acids are used for ATP
-decrease use of glucose for ATP production by most body cells so blood glucose levels remain high enough to supply brain
Stimuli for ---: Hypoglycemia, Deep sleep, Decreased fatty acids and increaesd amino acids in the blood, increased sympathetic stimulation
Stimuli for ---: Hyperglycemia, REM sleep, Increased fatty acids and decreased amino acids in the blood, Obesity, Low levels of thyroid hormones, high levels of hGH
Follicle Stimulating Hormone
FSH -- Gonadotropin releasing hormone, GnRH from hypothalamus stimulates gonadotrophs in anterior pituitary to produce FSH
In females: - stimulates secretion of estrogen - initiates the formation of follicle within the ovary
In males: Stimulates sperm production in testes
GnRH from hypothalamus stimulates gonadotrophs in anterior pituitary to produce LH
Females: secretion of estrogen and progesterone, ovulation, formation of corpus lutem
Males: secretion of testosterone
Hypothalamus regulates lactotroph cells by secreting PRH and PIH (dopamine)
-causes milk production
-suckling reduces levels of hypothalamic inhibition and prolactin levels rise along with milk production
Melanocyte Stimulating Hormone
-Secreted by corticotrophs in the anterior pituitary
-Excessive levels of CRH from the hypothalamus increases MSH release from the anterior pituitary
-PIH inhibits MSH release
-Function unclear in humans but high levels increase skin pigmentation
-Corticotropin releasing hormone (CRH) from the hypothalamus stimulates corticotrophs in the anterior pituitary to release ACTH
-ACTH stimulates release of glucocorticoids (mainly coritsol) from arenal cortex
-ACTH release is also stimulated by hypoglycemia, physical trauma, and IL-1
Thyroid Stimulating Hormone
-Hypothalamus regulates thyrotrophs in anterior pituitary to produce TSH (thyrotropin)
-TSH stimulates the synthesis & secretion of T3 and T4 (thyroid hormones)
-Metabolic rate stimulated
