Question

Salivation at the sight of smell of food is

• A. Peristalsis
• B. Reflex action
• C. Sympathetic action
• D. Parasympathetic action

Answer 1

The correct option is B Reflex action

Peristalsis is the muscular movement of the alimentary canal in the form of wave-like contraction of muscles. Our body functions 2 types of systems, sympathetic and parasympathetic system. Both of them are parts of the autonomic nervous system. Sympathetic action is responsible for fight and flight reactions of the body and parasympathetic system is responsible for the rest and digest of our body.

Reflex action can be said to a part of the nervous system that arises from the spinal cord. It is an involuntary and instant movement in response to a stimulus.

So, option B reflex action is the correct answer.
