Question

Main parts of a neuron?????

Answer 1

Hi.

The neuron is the building block of the nervous system. It is a relay system of the body and the construction is similar to that.

The neuron consists of:

Cyton or the cell body which has the nucleus and the mitochondria and ribosomes of the cell. They provide the power and the growth of the cells. They can be modified in the sensory system as corpuscles.

The dendrites which act as the recieving centres. They connect with the axons of multiple neurons and form interlinking chains between the cells. They also form free nerve endings in sensory neurons.

The axon, which is just the modified dendrite. It forms the outlet of the cell. The outgoing signals are transmitted in the form of the neurotransmitters. They interact either with dendrons of other neurons, or with muscles at the motor end plates. They can be myelinated or non-myelinated which alters the conduction speed from 0.3-0.5 m/s in unmyelinated neurons to around 60-120 m/s in myelinated neurons.

Answer 2

hey Friends ..


Neurons have three parts carry out the functions of communication and integration.
dendrites,axons and axon terminals.
