Oxytocin (ot: suckling infant stimulates nerve receptors in the nipple, resulting impulses travel along nerves to the hypothalamus, hypothalamus signals posterior pituitary to release ot, ot travels via bloodstream to mammary gland, breast ejects milk (lactation) Where do hormones come from: endocrine glands, organs that produce hormones as secondary function, i. e. : kidney and liver. Some nerves release hormones directly into the bloodstream (neurohormones). All primary endocrine glands and secondary endocrine tissue are innervated by neurons of the autonomic nervous system. Nerve signals, via local neurotransmitter release, can modulate hormone secretion.
