Question

Why don't we sense any pain when we clip or nail or cut our hari?

Answer 1

We do not feel any pain when we cut our nailsor hair because both nails and hair do not have nerves to send messages to the brain. They are dead cells.

Answer 2

In both the case
a specific cell called nerve cell is absent which is responsible for carrying message from part of body to brain and visa versa . because of that we don't feel any pain as hair or nail ((class 9 cannot write under bracket )(as it is a permanent tissue )
