What does ADH do | stimulates water reabsorption by distal & collecting tubules of kidneys |
What does ADH do in large pharmacological doeses | stimulates smooth muscle of blood vessels |
What does a lack of ADH result in | Diabetes. Insipidus{polyurea cant retain water} |
ADH is produced by | Hypothalmus |
Where is oxytocin(OT) produced | posterior pituarary gland |
oxycotin is synthesized by | neurons in paraventricular nucleus of hypothalmus |
Oxycotin does what?? | it stimulates the contractions of pregnant uterus & release of milk by lactating breast |
What happens to ADH, if it has an increased extracellular fluid osmotic pressure | decreased ADH secretion |
A decreased ECF(extra cellular fliud) leads to what | increased ADH secretion |
What does stress lead to | to an increase ADH secretion |
what does stimulation of nipples by infant lead to | increased oxycotin secretion, stretch receptors in cervix send impulses to hypothalamus during delivery |
where are the thyroid glands located | in the neck, below layrnx |
what are the 2 lateral lobes connected by | isthmus |
The thyroid glands contains microscopic spherical sacs called | thyroid follicles |
how do follicular cells manufacture thyroid hormones | by attaching iodine to the amino acid thyrosine |
what produces calcitonin(CT) | parafollicular or C cells |
thyroid horomone(throxine-T) does what | stimulate rate of oxygen consumption(metabolic rate of cells),regulates physical & mental development, development of sexual maturity |
Calictonin is produced by what gland | thyroid gland |
Calictonin does what to the blood calcium concentrations | decreases |
hypothyrodism in adult of the thyroid gland is | myxedemia(dry skin) |
what is another name for hypothyrodism in infant of thyroid gland is | cretinism |
A lack of iodines can lead | to a simple goiter |
where are the parathryoid glands located | attached to the posterior surface of thyroid glands |
parathyroids are | small round bodies usually 4 or 5 in # |
parathyroid glands contain | principal(chief) cells |
what do the principal chief cells produce | parathyroid hormone(parathormone) |
how does parathyroid hormone increases blood calcium | bone breakdown which releases calcium & phosphate into blood from bone, acclerating calcium absorption from kidneys tubules |
parathyroid glands to act on kidneys to form?? | Calictriol |
Calictriol is an active form of | Vitamin D |
vitamin D acts on intestine to do what? | to increase absorption of calcium, phosphate, & magnesium |
what are the effects of hypersecertion on parathyroid gland | decrease in bone mass with replacement by fibrous tissue; more easily fractured |
what are the effects of hyposecretion on parathyroid gland | produces hypocalcemia leading to muscle twitches, spasms, & convulsions(called tetany) may lead to death in few hours |
