Document Summary

Neuroendocrinology: interaction between the nervous system and the endocrine system. Hormone: chemical secreted by a gland that travels through the bloodstream and regulates target organs and tissues. Endocrine glands: secrete chemicals into the blood stream. Exocrine glands: use ducts to secrete glands outside the body. Neurotransmitters: travel short distances, precise destination, high concentration reaches target cell, rapid effects (msec) Hormones: travel long distances, spread throughout body, low concentration reaches target cell, receptors have extremely high af nity, slower effects (sec to min) Neuroendocrine communication: neuroendocrine cells blend neurocrine and endocrine communication: receive nt signals, integrate psp"s, re action potentials, but, they release hormones into the bloodstream, ex: neuroendocrine cells in the hypothalamus. Three classes of hormones: peptide hormones, small proteins, hydrophilic, includes all hypothalamic/pituitary hormones, amine (a. k. a monoamine) hormones, modi ed amino acids, hydrophilic, steroid hormones, derived from cholesterol, lipophilic.
