Document Summary
Hormones are produced by endocrine glands and play critical roles in growth and maturation; can be endocrine, paracrine, autocrine and intracrine; hormone-like molecules work to support hormones like igf-1 and gh. Can up-regulate and down-regulate (increase/decrease concentration) of receptors depending on concentration of circulating hormone, receptor affinity and target cell responsiveness. Work to create regulatory actions; morphogenesis is the regulation of physical growth/maturation with growth-promoting hormones; integration is the whole body response to internal/external stimuli; maintenance works to maintain an internal environment. Positive feedback widens the gap and negative feedback narrows it. Growth promoting factors are involved in growth, aging, recovery from injuries, burns, surgery, cancer and can be used in therapeutic models. Hypothalamic/pituitary hormones are releasing or inhibiting to modulate the release of anterior pituitary hormones; constantly communicate with the hypothalamus and released in pulses. Hypothalamic releasing/inhibiting hormones are stuff like growth hormone releasing hormone.
