Adrenal glands
pyramid shaped glands located on the superioir surface of each kidney
Adrenal medulla
a cluster of neurons which are part of the sypathetic nervous system
Adrenal cortex
forms the bulk of the gland
Adrenal cortex
all adrenal hormones help the body cope with danger, terror, or stress
Adrenal medulla
secretes amine proteins that enhance the fight or flight response
Epinephrine
a hormone that has an important role in the fight and flight response; prepartion for emergency
Norepinephrine
increas the force of skeletal muscle contraction and rate and force of contraction of the heart
Adrenal cortex
is composed of three layers which all secretes corticosteroids
Zone glomerulosa
a zone in the cortex which secretes aldosterone
Zona fasiculata
a zone in the cortex which secretes cortisol
Zona reticularis
a zone in the cortex which secretes DHEA
adrogens: testosterones, estrogen
these are produced in the Zona glomelurosa
glucocorticoids:cortisol, cotisone
these are produced in the Zona fasiculata
Mineralcorticoids: aldosterone
these are produced in the Zona reticularis
Corticosteroids
steroid hormones secreted by the adrenal cortex. This includes mineralcorticoids, glucocorticoids, androgen DHEA
Dehydroepiandrosterone
DHEA meaning
Thymus
an important organ in the immune system
Thymus
secretes thymic hormones that are essential for the production of T lymphocytes
Aldosterone
primary steroid hormone of the mineralcorticoids
Cortisol
primary steroid hormone of the glucocorticoids
Dehydroepiandrosterone
primary steroid hormone of androgen
Aldosterone
this hormone help conserve body fluid by acting on kidnets and increasing reabsorption of Na and water in renal tubules
Cortisol
this hormone help the body cope with stress by stabilizing blood glucose levels; in large quantities they also inhibit inflammation and the immune system
Dehydroepiandrosterone
a weak androgen, and estrogen
DHEA
this hormone is responsible for the androgenic effects of adrenarche
DHEA
potentiated locally via conversion into testosterone and DHT in skin and hair follicles
Gonads
gamete production, hormone regulation, regulation of fertility
Estrogen
this hormones regulate femal secondary sexual characters and sexual behavior
from follicles
where does estrogen come from
Progesterone
maintains pregnancy and prepares mamary glands for lactation
from corpus luteum
where does progesterone come from
Androgen testosterone
this hormone regulate male secondary sexual behaviour and sexual characters
testes
where does the testosterone come from
chrorionic gonadotropin
this hormone maintains normal pregnancy
from placenta
where does the chrorionic gonadotropin come from
Ovary
female gonads
Relaxin
relaxes the pubic ligamets, soften and enlarge the opening to the cervix during parturition
Testes
sprem production and development of male repoductive tissues
Leptin
communicate how much fat is stored in the body
Adiponectin
related to physiological response to insulin
adipose cells
aleptin, resistin, and adiponectin
Enteroendocrine
release peptide hormone that regulate digestion
Cardiac cells
secretes atrial natriuretic peptide which stimulates loss of body fluids and salts through the production of sodium rice urine
Placenta
secretes hormones of pregnancy including human chrorionic gonadotropin
Renin
helps control your blood pressure and maintain healthy levels of sodium and potassium in your body
Erythropoietin
stimulates red blood cell production
Kidneys
secretes renin and erythropoietin
osteocalcin
promotes release of insulin
Bones
secretes osteocalcin
chlolecalciferol
an intermediate in vitamin D production
Skin
secretes cholecalciferol
