Document Summary

*b. ductless: square, autonomous, confined to mesodermal tissues. *a. biologically inert, by themselves: used as energy sources. c, always stored in secretory granules, always released by exocytosis incorporated as structural moieties into other molecules. Binding proteins do not: bind protein hormones, bind steroid hormones, bind thyroid hormones, prevent hormone degradation. The actions of protein hormones are usually mediated by: cytoplasmic receptors, nuclear receptors, cyclic ribosomal adenosine phosphate (crap). Oxytocin and antidiuretic hormone are: complex steroids, synthesized and stored in the posterior pituitary, released from the anterior pituitary when blood is hypotonic. *d. synthesized in the hypothalamus and released from the posterior pituitary: two names for the same hormone. *a. increased during stress: reduced during hemorrhage, reduced by increased blood osmolality, increased by alcohol, increased in hypothalamic diabetes insipidus (di). Oxytocin: is not produced in males, inhibits lactation. *c. stimulates smooth muscle contraction. d. e. is derived from a precursor (neurophysin-oxytonic peptide ester, (nope). is necessary for parturition.
