Power of regeneration is lowest in :-A Brain cell B Liver cell C Bone cell D Muscle cell

The power of regeneration is lowest in:

A. Brain cell

The brain cell, also known as a neuron, has the lowest power of regeneration among the options provided. Unlike other cells in the body, neurons do not undergo cell division, and therefore, once they are damaged or die, they cannot be replaced. This is why brain injuries or neurodegenerative diseases can have such severe and lasting impacts.

In contrast, liver cells have a high capacity for regeneration, which allows the liver to recover even after significant damage. Bone cells and muscle cells also have some capacity for regeneration, although this process can be slow and may not always restore full function.
