BIOL 120 Lecture Notes - Lecture 7: Hypophyseal Portal System, Pars Tuberalis, Pars Intermedia
Document Summary
Secretes endocrine hormones, but does not make them. The axon goes down to the median eminence which have axons that release hormones. The hormones are picked up by the primary capillary plexus, transported down to the secondary capillary plexus. Secondary capillary plexus transport hormones out of the pituitary gland, diffusing out and binding to endocrine cells. Inhibits the cells to not release hormones. No effect in the toes, fingers, no effect anywhere except anterior lobe. They are swollen regions in the terminal knob (hormones within it) Make hormones in the hypothalamus and store them in the posterior only herring bodies tell when or when not to make and secrete hormones from the anterior side. Can stimulate the inhibitory hormone, or release the inhibitory hormone. When growth hormone is produced in pituitary, most of them go to the liver. Somatomedins is the major product of growth hormones.
