Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Anti-diuretic hormone (ADH) is released by which gland of the endocrine system
A
Thyroid
B
(Posterior) Pituitary
C
Ovaries
D
Adrenal
Explanation: 

Detailed explanation-1: -Your pituitary gland is a part of your endocrine system. The posterior pituitary stores and releases just two of the many hormones your pituitary gland is responsible for: oxytocin and antidiuretic hormone (ADH, or vasopressin).

Detailed explanation-2: -ADH is a substance produced naturally in an area of the brain called the hypothalamus. It is then released by the pituitary gland at the base of the brain.

Detailed explanation-3: -Hyperosmolar states most strongly trigger its release. ADH is stored in neurons within the hypothalamus. These neurons express osmoreceptors that are exquisitely responsive to blood osmolarity and respond to changes as little as two mOsm/L. [2] Therefore, slight elevations in osmolarity result in the secretion of ADH.

Detailed explanation-4: -The posterior lobe produces two hormones, vasopressin and oxytocin. These hormones are released when the hypothalamus sends messages to the pituitary gland through nerve cells. Vasopressin is also known as antidiuretic hormone (ADH).
