Question

What is the function of receptors in our body?

• A. All information from the environment is detected by receptors
• B. Receptors pass information in the form of electrical impulses to the brain
• C. Receptors pass information in the form of mechanical impulses to the brain
• D. Both A and B

Answer 1

Answer: (A)

All information from the environment is detected by receptors

Receptors are biological transducers that convert energy from both external and internal environments into electrical impulses. They may be massed together to form a sense organ, such as the eye or ear, or they may be scattered, as are those of the skin and viscera. Receptors are connected to the central nervous system by afferent nerve fibres.

So, the correct answer is option A.
