These systems all work together to determine what the behavioral output will be! How the endocrine system works: - Many levels of control! - The hypothalamus in the brain is the initial control center – produces and secretes “Releasing hormones”. - “Releasing hormones” stimulate the anterior pituitary to release “Tropic hormones” Tropic hormones – hormones that control the activity of other endocrine glands - Tropic hormones stimulate other glands to produce specific hormones In each case it works this way – external stimulus > hypothalamus production of releasing hormone > pituitary production of tropic hormone > target endocrine gland produces specific hormone

Unformatted text preview: behavioral or physiological alteration Before understanding how these systems, interact, we need to understand how they work separately: HPA Axis (Hypothalamic-Pituitary-Adrenal Axis) – the “stress” axis This axis works just as I described above – stressor elicits release of the releasing hormone Corticotropic releasing hormone (CRH) from the hypothalamus release of Adrenocorticotropic hormone from the anterior pituitary release of epinephrine & norepinephrine (seconds) and corticosterone (minutes) from the adrenal gland.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
