Document Summary

Anatomy and physiology ii: chapter 17 endocrine system. Integration and coordination: accomplished by nervous and endocrine, referred to as neuroendocrine system, work as complements, maintain homeostasis! Nervous vs. endocrine: nervous, electrochemical, very fast (1-10 ms, only muscles/glands, ends quickly, may stimulate hormone release, endocrine, chemical, slow (seconds to days, most tissues in the body, continues for days, stimulate an inhibit. Overview of endocrine: endo (cid:862)within(cid:863, crine (cid:862)to separate(cid:863, secrete products to distant tissues, major role in, growth and devolpment, reproduction, total body metabolism. Transportation of hormones: endocrine glands are highly vascularized, filled with blood vessels, heal easily, hormones travel in blood vessels, transported to target organ. Negative feedback mechanisms: stimulation increases secretion, stimulation increases blood concentration, target organ is affected, hormone release inhibited. Thyroid: largest gland, only gland to store hormones in large quantity, primary effect increase metabolic rate. Parathyroid gland: at least two pairs, parathyroid hormone, produced by chief cells, opposite effect of calcitonin.
