Document Summary
Characteristics of hormones: control: synthesis and release are controlled by tissues/organs (i. e. hypothalamus-pituitary axis, feedback: negative/positive, patterns of secretion, metabolism, elimination, receptor binding: must locate and attach to target, action: effects on target cells, tissues, organs. Which induce a neurologic response to receptive organs (fight or flight) Catecholamines and cortisol are released in response to stim of sypm, hp axis and adrenal glands. (fight or flight) Prepare body for short and mild stress. Suppresses certain hormones: gh, thyroid, reproductive (to conserve energy) Activates certain hormones: adh (maintain bp: resistance stage: Cortisol helpful in the beginning but detrimental long term. Suppression of gh, thyroid and reproductive cause long term probs, and adh leads to htn and fluid retention: exhaustion stage: depletion of energy and poor health. Energy creation: metabolism by breaking down proteins, releasing lipids, increasing glucose. Excessive loss of body proteins and break down of tissues. Altered hormone function: impairment of endocrine gland: damage to hp axis or glands.
