________ controls hormone concentrations. Select one: A.Muscle contraction B.Negative feedback C.Positive feedback D.Exposure to sun
somatostain
has the action of Helps regulate carbohydrates and the Source of Control is Not determined
Thyroxine (T4)
has the action of Increases rate of energy release from carbohydrates; increases rate of protein synthesis; accelerates growth; necessary for normal nervous system maturation and the Source of Control is TSH from the anterior pituitary gland
Calcitonin
has the action of Lowers blood calcium and phosphate ion concentrations by inhibiting release of calcium and phosphate ions from bones and by increasing the rate at which calcium and phosphate ions are deposited in bones; increases excretion of calcium by the kidneys and the Source of Control is Elevated blood calcium ion concentration, digestive hormones
insulin
has the action of Promotes formation of glycogen from glucose, inhibits conversion of noncarbohydrates into glucose, and enhances movement of glucose through adipose and muscle cell membranes, decreasing blood glucose concentration; promotes transport of amino acids into cells; enhances synthesis of proteins and fats and the Source of Control is Blood glucose concentration
Triiodothyronine (T3)
has the action of Same as, but five times more potent than thyroxine and the Source of Control is TSH from the anterior pituitary gland
glucagon
has the action of Stimulates the liver to break down glycogen and convert noncarbohydrates into glucose; stimulates breakdown of fats and the Source of Control is Blood glucose concentration
symphysis that is amphiarthrotic.
he joint between adjacent vertebral bodies is a Select one: A.symphysis that is diarthrotic. B.symphysis that is synarthrotic. C.synovial that is synarthrotic. D.symphysis that is amphiarthrotic.
