Question

antidiuretic hormone is produced by the:
a hypothalamus
b posterior pituitary
c anterior pituitary
d thalamus

Explanation:

Antidiuretic Hormone (ADH), also known as vasopressin, is synthesized by the hypothalamus. The posterior pituitary stores and releases it, but the production (synthesis) occurs in the hypothalamus. The anterior pituitary produces other hormones like growth hormone, prolactin, etc. The thalamus is involved in sensory and motor signal relay, not hormone production. So the correct option is A.

Answer:

A. Hypothalamus
