Question

Extension of sympathetic nervous system is

• A. Adrenal medulla
• B. Adrenal cortex
• C. Pineal
• D. Neurohypophysis

Answer 1

The correct option is A Adrenal medulla

Sympathetic nervous system is a division of autonomous nervous system (ANS). ANS has two parts, sympathetic and parasympathetic, both of which are antagonistic to each other in effects. Sympathetic nervous system produces effects on body in response to epinephrine or adrenaline hormone secreted from adrenal medulla. Adrenaline is known as emergency hormone and induces fight or flight response in body whenever homeostasis of body is disturbed.

So, the correct answer is 'Adrenal medulla'.
