Question

Name the body part which has division-less cells.
Option A- Brain
Option B- Lungs
Option C- Kidney
Option D- Stomach

Answer 1

Hint: There are various types of cells present in our body. The cells that do not divide after birth and are divided and differentiated during embryonic development life are referred to as division less cells.

Complete answer:
Division less cells do not divide after birth like other cells of the body divide to replace the damaged and old cells. These cells are differentiated and divided early during embryonic stage.

Option A- Brain: Brain consists of neuron cells and these cells are divided and differentiated during the embryonic development and do not divide after birth of the child.

Option B- Lungs: The air sac cells required for the exchange of gases regenerate and divide within a time period of one year whereas the surface cells of lungs renew after every 2nd or 3rd week. So, these lung cells are not division less cells.

Option C- Kidney: Kidney cells regenerate and repair themselves throughout the entire life of a person. Latest studies show that kidneys have the capacity to regenerate themselves.

Option D- Stomach: Stomach cells regenerate themselves and repair also. A human gets a new stomach lining every 3 to 4 days.

So, the correct answer is Option A- Brain.

Note:
The most common brain cells are neurons and non neuron cells are known as Glia. In the human brain the average count of neuron cells is about 100 billion neurons. Neurons cells are famous brain cells but for the functioning of the brain both neuron and glial cells are very important. Glial cells are also known as glial cells. These cells provide support and function to the neuron cells and form myelin. These cells have subtypes and designed for some specific function.
