Describe how a molecule of CRH released by neurosecretory ce

Describe how a molecule of CRH released by neurosecretory cells into the primary capillary plexus of the hypothalamic-pituitary system, travels to the anterior pituitary gland to effect release of ACTH by corticotrophs.

Solution

The hypophyseal potal system is the vascular pathway that connects the brain and the hypothalamus. This the route through which the hormones moves to and from the hypothalamus and anterior pituitary.

Thus, the CRH (corticotropin releasing hormone) secreted by the neurosecretory cells of the hypothalamus travels down the anterior pituitary via the \"hypophyseal portal veins.\"
