Document Summary
Neuroendocrine: hypothalamic hormones that regular the anterior pituitary. Carry hormones to target cells that contain specific receptor proteins for that hormone. Target cells can respond in a specific fashion. Response to stress (injury, danger, psychological/emotional stress, temperature) in many hormones plasma (epinephrine) Control of many processes in multiple tissues requiring coordination of complex events at the whole body level. Ion and fluid balance adh and aldosterone (renal section) Energy metabolism fuel storage and utilization insulin, glucagon, thyroid hormones, and others. Growth and development gh, th, etc. Target cell must have specific receptor proteins. Combination of regulatory molecule with its receptor proteins must cause a specific sequence of changes. There must be a mechanism to quickly turn off the action of a regulator.
