Increases intestinal absorption of Ca independent of 1,25(OH), D3

Binds osteoblastic receptors to stimulate osteoclast activity

Secretion is increased by the rise in plasma Ca concentration

Decreases the production of 1,25 (OH), D3

Decreases the production of 1,25 (OH), D3

Increases activity of Ca pump of osteocytic membrane

Inhibits the activity of 1a-hydroxylase of the proximal renal tubules

Action is opposite to parathyroid hormone as regard PO4- and Ca2+

Augments glycogenolysis produced by glucagon

Promotes protein catabolism in hepatic tissue to provide amino acids needed for gluconeogenesis

Decreases glucose utilization by the brain and lowers its insulin sensitivity

secretion is highest at the evening and lowest at the early morning

Is an important physiologic regulator of aldosterone secretion

Is secreted at a constant level throughout the day

Causes hyperpigmentation whenever it is chronically increased

Has no effect on the size of cells in the zona fasciculata and zona reticularis

Short stature (being a dwarf)

Loss of weight despite of increased appetite.

Decreased heart rate and cardiac output

Is a calcium raising hormone

Rapid shift of calcium from the labile calcium pool to or from plasma,

Secretion of parathormone hormone

Activation of vitamin D3

Inhibition of calcitonin hormone.

cytoplasmic

membrane receptor

non-specific

Is produced by the thyroid gland.

Increases basal metabolic rate
