Biology - Chemical Coordination and Integration Question with Solution | TestHub
The hypothalamic hormones like Adreno-corticotropic releasing hormone and Thyrotropin Releasing hormone are conducted to the hypophysis through __________.
Options:
Answer:
Solution:
The hypothalamus secretes releasing and inhibitory hormones such as Adrenocorticotropic releasing hormone and Thyrotropin Releasing hormone.
These hormones regulate the secretions of the anterior pituitary gland (adenohypophysis).
They are transported from the hypothalamus to the anterior pituitary through a specialized blood vessel system known as the hypophyseal portal system, specifically via the hypophyseal portal vein.
This direct vascular connection ensures that the hormones reach the anterior pituitary in high concentrations without first entering the systemic circulation.
Answer: hypophyseal portal vein
