hesi exam (endocrine already passed
purpose of endocrine system - =assists the nervous system in maintaining homeostasis in the
body, plays a role in growth and sexual maturation
homeostasis - =the body"s adjustment internally to meet equillibrium with its external
surroundings
pituitary gland - =part of the brain controlling several hormone glands in the body including
thyroid and adrenalis, the ovaries and testes. divided into anterior and posterior regions
posterior pituitary gland - =maintains fluid levels in the body
anterior pituitary gland - =regulates secretion of hormones like those that stimulate the thyroid
and aids in metabolism, produces growth hormone, and controls reproductive functions in both
sexes
hypothalamus - =part of the brain that controls the pituitary gland, along with the body's
homeostatic systems (thirst, hunger, etc.), and involved in sleep and emotional activity
hormones - =chemical messengers that control the growth, differentiation, and metabolism of
specific target cells
steroid hormones - =hormones that enter the target cells and have direct effect on the DNA of the
nucleus
non-steroid hormones - =hormones that dont enter target cells and are mainly protein hormones,
which remain at the cell's surface and act through a second messenger, usually through
adenonsine monophosphate (AMP)
other organs that produce hormones - =stomach, small intestine, and kidneys
