Document Summary
Subject thyroid hormone needs stimulation from tsh - which is transported through the body through the hhps. Prolactins release is stimulated by the inhibition of dopamine dopamine inhibits prolactin dopamine goes through the body through hhps so if there was not hhps then dopamine isn"t circulating therefore prolactin is stimulated. Growth hormone releasing hormone is produced in the hypothalamus - goes to anterior pituitary - goes through the hhps so if hhps ws destroyed then this hormone would not circulate. Steroid hormones dont dissolve in water so travel through bloodstream (blood plasma is made from primarily water) Hypothalamus neurons synthesize neurohormones that are released onto capillaries of the hypothalamic-hypophyseal portal systems (blood vessels) Portal veins of the hhps carry the neurohormones to the anterior where they act on endocrine cells (in anterior) Endocrine cells release peptide hormones into the second set of capillaries of the. Hhps for distribution to the rest of the body.
