Question

Pituitary gland of adult rat is surgically removed. Which of the following endocrine glands will be less affected?

• A. Thyroid
• B. Gonads
• C. Adrenal cortex
• D. Adrenal medulla

Answer 1

The correct option is D Adrenal medulla

Adrenal medulla secretes adrenaline and nor adrenaline hormones which activate sympathetic and parasympathetic nervous system of the body which induce fight or flight responses in the body. Secretion of adrenaline and nor adrenaline is not stimulated or inhibited by any other hormone. They are secreted in response to stress conditions in the body. So, adrenal medulla won't get effected if pituitary gland of adult rat is surgically removed.

Pituitary gland secretes many hormones that stimulate the release of hormones from other endocrine glands such as thyroid, gonads, adrenal cortex and pineal gland.

So, the correct answer is 'Adrenal medulla'.
