Question

Why can't neurons divide?

Answer 1

Hint: Your body's command center is your nervous system. It controls your motions, thoughts, and automatic responses to the world around you from your brain. It also regulates other systems and processes, such as digestion, breathing, and sexual growth (puberty).

Complete answer:
Neurons are the nervous system building blocks. Signals are sent and sent to various parts of the body. This is done physically and electrically. The transmission of information is made possible by various types of neurons.
The sensory neurons convey information throughout the body from the sensor cells to the brain. The motor neurons pass information to the muscles from the brain. The interneurons transmit information across the body's various neurons.
The following reasons why neurons can’t divide after birth:
1. A cell must go through Mitosis or Meiosis in order to divide. Because neurons are somatic cells, they must go through Mitosis.
2. Centrioles must move to the poles and develop spindle fibers that pull the chromosomes together for Mitosis to occur.
3. Neurons lack Centrioles, making Mitosis impossible and preventing division.

Note:
A neuron's important functions are:
1. Chemical Synapse-
In chemical synapses, other neurons are affected by a gap between two neurons called the synapse. The potential for action is transferred throughout the axon to a postsynaptic termination, which initiates chemical messengers known as neurotransmitters. These neurotransmitters stimulate the postsynaptic neurons, which create their own action potential.
2. Electrical synapse-
If a gap connection connects two neurons, an electrical synapse results. These gaps include ion channels that help to transmit a positive electric signal directly. This is much quicker than chemical synapses.
