participates in the maintenance of homeostasis by regulating and coordinating other body systems
protein molecules capable of binding a particular hormone and generating a cellular reponse
hormones secreted into the interstitial fluid and diffusing into capillaries normally to cells that need to send message to whole body. and make up about 90% of all hormones in our body
act on cells without entering the cardiovascular system usually needed for a more precise regional area of the body.
this type of hormone requires transport proteins to dissolve in blood plasma. Includes steroid hormones, thyroid hormones and nitric oxide.
this type of hormone freely dissolves in blood plasma and includes amine hormones, peptide and protein hormones, glycoprotein hormones and eicosanoid hormones.
lipid-soluble hormones ______ pass through cellular membranes and bind to receptors inside the cell.
steroids, aldosterone, cortisol, androgens, calcitriol, testosterone, estrogens, progesterone, thyroid hormones, and gases such as nitric oxide are examples of ______ ______ hormones.
Amines, peptides, proteins such as ADH and oxytocin, eicosanoids are all examples of ______ ______ hormones.
Water-soluble hormones bind to a receptor this causes activation of ______ ______ (s) inside the cell. these are also known as the following acronym _____.
second messenger, cAMP
The ______ ______ inside the water-soluble hormone initiates the processes the hormone was sent to promote
Protein kinases attach a phosphate group to a new molecule that didn't have phosphate previously which can result in either an excitatory or inhibitory response. This process is called ______.
when the effect of two hormones together are greather than the effect of either hormone added together
occurs when a hormone requires another hormone to be present in order to function.
this is an example of which type of hormone interaction? : thyroid hormone is required to be present for epinephrine to stimulate the breakdown of triglycerides in significant quantities
some examples of organs not classified as endocrine glands but contain hormone producing cells
thymus, pancreas, ovaries, testes
Neurosecretory cells in the ______ release five different hormones which stimulate secretion of ______ ______ hormones.
hypothalamus, anterior pituitary
type of cell which secretes follicle-stimulating hormone (FSH) and lutenizing hormone (LH)
type of cell that secretes adrenocorticotropic hormone (ACTH) or corticotropin and melanocyte-stimulating hormone
HGH is responsible for stimulating the secretion of ______ ______ ______ that stimulate body growth and metabolism.
insulinlike growth factor
TSH stimulates the synthesis and release of two thyroid hormones;
triiodothyronine, thyroxine (or tetraodothyrorine)
OOcyte and ovarian follicular development in women, and sperm production in men is promoted by this hormone
Follicular stimulating hormone
this hormone causes ovulation, simulates progesterone production and ovarian estrogen in females, and testosterone production in males
this hormone controls synthesis and release of glucocorticoids from the adrenal cortex
two hormones synthesized in the hypothalamus but secreted by the neurohypophysis are
antidiuretic hormone, oxytocin
______ is involved in calcium homeostasis and also stimulates kidneys to release calcitriol. Principal and Chief cells are responsible for the production of this hormone.
this superficial layer of the adrenal gland, produces mineralocorticoids suchas aldosterone which affect mineral homeostasis.
This layer of the adrenal gland produces glucocortcoids, hormons affecting glucose homeostasis
this layer of the adrenal gland produces weak androgens in women these androgens are converted into estrogens
a modified sympathetic ganglion of the autonomic nervous system. the ______ cells produce epinephrine 80% and norepinephrine 20% and work with the sympathetic nervous system in times of stress.
These cells are most common in pancreas, produce insulin, and make up 70% of pancreatic islet cells.
______ ______ inhibits somatostatin release, gall bladder contraction and pancreatic enzyme release.
In addition to estrogen, ovaries produce _______ and ______ the second which aids in childbirth.
These five hormones regulate the menstral cycle.
estradiol, estrone, progesterone, follicular stimulating hormone and luteinizing hormone
This gland is composed of neuroglia and produces melatonin, the hormone responsible for our circadian rhythm.
This gland contributes to the development and maturation of T lymphocytes and may slow the effects of aging.
