Question

We do not sense any pain when we clip our nails or cut our hair. Why?

• A. They are made up of dead cells.
• B. These parts cannot respond to touch.
• C. They can tolerate pain.
• D. None of these.

Answer 1

The correct option is A They are made up of dead cells.

• Hairs and nails are made of dead tissues. Only the base of the hair and the base of the nail have living cells.
• Since dead tissues are devoid of nerve supply, the sensation of pain cannot be conveyed to the brain.
• Thus, the correct answer is option A.
