Question

Describe Three Parts of Human Body If We Cut Them We do not feel Pain 1.Nails, 2.Hairs, 3

Answer 1

There are only 2 body parts nails or hair which we cut and don't feel pain

Answer 2

Answer:

Option 3 is a part of teeth.

Explanation:

• The sensation of pain occurs because of nerves or nerve endings present in the area because on receiving the stimulus, they send the signal to the brain and hence the pain sensation is felt and body reacts.

• But there are areas, which are devoid of these nerve endings and therefore, pain sensation cannot be felt.

• We can also say that dead cells are present in these areas.

• Nails and hair are one such examples and enamel part of the tooth is the third because enamel is devoid of nerve endings and only the inner part of the tooth called the pulp, has proper nerve ending which receives the sensations along with dentin.

• Therefore, when a tooth gets decay at superficial level, pain is not felt.

Hence, some part of the teeth (enamel) is the third human body part which do not feel pain upon cutting.
