|
Definition
1) neural structures are derived from neuroectoderm of diencephalons (infundibulum). 2) is connected to CNS 3) embryonically, a surface ectoderm projection from oral cavity. 4) no connection to stomadeum--starts as hollow structure from adenohyphosis. |

Hypothalamo-Adenohypophyseal Portal System |
|
Definition
Venous Portal System from brain (hypothalamus) to Adenohypophysis. Direct transport of releasing factors which tell the capillary bed stimulate the pars distalis of the Adenohyophysis to release GH, TSH,ACTH,LH,FSH,MSH |
