Which of the following is an accumulation and release center of neurohormones?

  1. Anterior pituitary lobe
  2. Posterior pituitary lobe
  3. Intermediate lobe of the pituitary
  4. Hypothalamus

Answer

(2) Posterior pituitary lobe

Solution

As per NCERT, the neurohypophysis (pars nervosa), also known as the posterior pituitary, stores and releases two hormones, oxytocin and vasopressin, which are actually synthesised by the hypothalamus and transported axonally to it.

The hypothalamus makes the neurohormones; the posterior pituitary lobe accumulates and releases them.
