Question

The posterior pituitary is under the-

• A. Direct axonal regulation of the adenohypophysis
• B. Direct axonal regulation of the neurohypophysis
• C. Direct neural regulation of the adenohypophysis
• D. Direct neural regulation of the hypothalamus

Answer 1

The correct option is D Direct neural regulation of the hypothalamus

The hormones of pituitary (posterior part) are synthesized in the hypothalamus; packaged in secretory granules and are transported down the axons to be stored for release by posterior lobe.
Neurohypophysis also known as posterior pituitary, stores and releases two hormones- oxytocin and vasopressin which are synthesised by hypothalamus and transported axonally to neurohypophysis.
Therefore, posterior pituitary is under the direct neural regulation of the hypothalamus.
