Document Summary
Cellular response pathways in endocrine system differ between water-soluble and lipid-soluble signaling molecules: one difference between water soluble and lipid soluble molecules is location of target cell receptor proteins, water-soluble hormones have receptors in plasma membrane (figure. Hormones can elicit more than one response in the body: can do this if , target cells differ in receptor type or in type of molecules produced in response. The body"s endocrine glands vary in location as well as in the hormones produced: figure 45. 9** Coordination of endocrine system with nervous system is common in endocrine signaling: endocrine organs in brain combine functions of endocrine system with nervous system. Insects b: almost all insects belong to subclass pterygota (includes winged insects, these insects have either hemimetabolous or holometabolous development, hemimetabolous: a. Important in social behavior, sexual motivation, pair bonding: oxytocin, functions in milk secretion in mammals, regulates uterine contractions at birth iii.
