ANSC 3316 Lecture Notes - Lecture 2: Digestion, Suprachiasmatic Nucleus, Posterior Pituitary
Document Summary
Hormones control: growth and development, metabolism, digestion, energy reduction, extracellular fluid, adaption to hostile environment, reproduction, very rarely do hormones work alone. Level at which hormone actions are considered: whole body level. Endocrine hierarchy: central nervous system"s neural impulse/systems contribute to stimulate the release of. + an endocrine target hormones, and then a non-endocrine target: central nervous system"s neural impulse/systems contribute to stimulate the release of. Neurosecretory cells in posterior pituitary gland which then is released to a non- endocrine target. Hormone controls its own secretions as a result of its release or its action. Long loop hormone or end product feeds back to inhibit release of stimulatory hormones. Short loop hormone feeds back to inhibit its own releasing factor. Ultra-short loop hormone feeds back to inhibit its own release. There are some anomalies, however, that don"t work this way.
