Document Summary

The endocrine systems influences metabolic activity by means of hormones (hormone= to excite). Binding of a hormone to a cellular receptors initiates responses that typically occur after a lag period of seconds or even days. The major process that theses mighty molecules control and integrate include: reproduction, growth and development, maintenance of electrolyte, water, and nutrient balance of the blood, regulation of cellular metabolism and energy balance, mobilization of body defenses. Endocrinology: the study of hormones and the endocrine organs. There are two types of glands exocrine (produce non-hormonal substance like sweat and saliva) and endocrine (produce hormones and lack ducts) The endocrine gland includes the: pituitary, thyroid, parathyroid, adrenal, pineal glands. Hypothalamus (considered neuroendocrine organ) produces and releases. Autocrine and paracrine are short distance signals. Autocrine: chemicals that exert their effects on the same cell that secrete hormones them. Paracrine also act locally but they affect cell types other than those releasing the paracrine chemical.
