Why is It Important That You Take Care of Your

Question

Why is it important that you take care of your neurons?
A) They are able to divide rapidly and can be turned into cancer cells.
B) They only undergo mitosis after the brain has obtained enough sleep.
C) They are unable to divide by mitosis.
D) They are very susceptible to mutations of their DNA.

Accepted Answer

Neurons are unable to divide by mitosis, which means that the number of neurons a person has is fixed. This makes it important to take care of existing neurons as they cannot be replaced if damaged or lost. Options A and D are incorrect because neurons do not divide rapidly nor are they particularly susceptible to DNA mutations. Option B is also incorrect as the process of mitosis is not involved in the maintenance of neurons.
