Endocrine Glands and their hormones

Bio 117 - Exam 2

location of melatonin secretion

pineal gland

types of hormones secreted by the pineal gland

amines

function of melatonin

regulates internal body rhythms (daily and annual cycles)

location of growth hormone (GH) secretion

anterior pituitary

location of prolactin (PRL) secretion

anterior pituitary

location of adrenocorticotropic hormone (ACTH) secretion

anterior pituitary

location of thyroid stimulating hormone (TSH) secretion

anterior pituitary

Two types of gonadotropins are ______ and ______

follicle stimulating hormone (FSH) and luteinizing hormone (LH)

location of gonadotropins (FSH and LH) secretion

anterior pituitary

location of β-endorphin secretion

anterior pituitary

location of β-lipotropin (β-LPH) secretion

anterior pituitary

location of melanocyte stimulating hormone (MSH) secretion

anterior pituitary

function of growth hormone (GH)

stimulates body growth and cell mitosis

function of prolactin (PRL)

stimulates milk production is mammary glands

function of adrenocorticotropic hormone (ACTH)

increases production and secretion of adrenal cortex steroid hormones related to stress and water balance

function of thyroid stimulating hormone (TSH)

Increases production and secretion of thyroid hormones such as thyroxine

function of follicle stimulating hormone (FSH) (one of the gonadotropins)

stimulate development of testes/ovary and production of sperm/eggs

function of luteinizing hormone (LH): (one of the gonadotropins)

production of gonadal sex steroid hormones

function of β-endorphin

suppresses pain; may act as an “endogenous opioid (opiate)”

function of β-Lipotropin (β-LPH)

affects lipid metabolism, primarily by lipolysis

function of melanocyte stimulating hormone (MSH)

In animals, MSH stimulates melanocytes to produce melanin. Not actually secreted in humans, but can created by ACTH cleavage. Functional importance in humans: unknown

types of hormones secreted by the anterior pituitary

peptides, proteins, and glycoproteins

location of oxytocin (OT) secretion

posterior pituitary gland

location of vasopressin (AVP) / antidiuretic hormone (ADH) secretion

posterior pituitary

function of oxytocin (OT)

stimulates contraction of muscles in uterus to drive birthing contractions during "labor," and stimulates mammary gland muscles to release milk

function of vasopressin (AVP) / antidiuretic hormone (ADH)

decreases the amount (volume) of urine produced by the kidneys and increases urine solute concentration in order to conserve water in the body

types of hormones secreted by the posterior pituitary gland

peptides
