P. pituitary and A. pituitary differ in what hormones they release and how they are released, as mentioned in pervious lecture P. pituitary Nothing more than capillary bed surrounded by axons…ADH and oxytocin released as neurohormones into capillary beds…travel through CS to area of interest and released at target tissue A. Pituitary hormones are not activated by nervous system…they are hormones produced to regulate the release of anterior pituitary….hypothalamus releases “releasing hormones” , that activate the A.P. and released into a capillary bed (pg. 41) just as with the P.P…these hormones then follow a vein to a second capillary bed in the A.P….this vein is known as a portal vein--a unique vessel in the CS because it is found between 2 capillary veins…these releasing hormones seek out cell s that have specific receptors, these cells trigger processing and release of hormones within the A.P…..the releasing hormones regulate the productivity of hormones within the A.P.within the A....
