22Stimulus of the endocrine system can be a specific chemical, regulatory hormone or neural.

23The functions of the hypothalamus are secretion of hormones that control the activities of the [blank_start]anterior pituitary gland[blank_end], synthesis and release of [blank_start]ADH and oxytocin[blank_end] in the posterior pituitary gland and controls the adrenal medulla which releases [blank_start]epinephrine and norepinephrine[blank_end].
- Ahypothalamus
- Bthalamus
- Canterior pituitary gland

30In calcium homeostasis, calcitonin works to [blank_start]lower[blank_end] calcium levels in the blood whereas parathyroid hormone works to [blank_start]increase[blank_end] calcium levels. These two hormones are therefore [blank_start]antagonistic[blank_end].

31Calcitonin in the thyroid gland [blank_start]lowers[blank_end] calcium levels in blood.

32Parathyroid hormone in the parathyroid gland [blank_start]increases[blank_end] calcium levels in blood. It's target cells are [blank_start]bones and kidneys[blank_end]. It stimulates [blank_start]osteoclasts[blank_end], inhibits [blank_start]osteoblasts[blank_end] and [blank_start]reduces[blank_end] excretion. It stimulates the [blank_start]kidneys[blank_end] to make calcitriol.

41The alarm phase consists of an [blank_start]immediate short term response to crisis[blank_end]. It is associated with the fight or flight reaction where [blank_start]epinephrine[blank_end] dominates. It includes a sympathetic response, and a reduction of water loss occurs.
- Aimmediate short term response to crisis
- Bimmediate long term response to crisis
- Cnorepinephrine
- Depinephrine
42The resistance phase includes [blank_start]long term[blank_end] metabolic adjustments. It occurs if stress lasts longer than a few [blank_start]hours[blank_end].
