your answer:--

➡neuron is the structural and functional unit of nervous tissue.
➡a neuron takes the signals from our body parts and transfer it to the CNS(central nervous system).
➡neurons can be further divided into three parts:-
↪sensory neuron :- this type of neuron takes the signals from the receptors and transfer it to the CNS.
↪motor neuron:- this type if neuron takes the signal from CNS and transfer it to the receptors.
↪relay neurons :- this neuron acts as a link between motor and sensory neuron.
➡ neuron is mainly present in the brain and spinal cord.
➡The cell body of a motor neuron is approximately 100 microns(0.1 millimeter) in diameter and as you now know, the axon is about 1 meter (1,000 millimeter) in length. So, the axon of a motor neuron is 10,000 times as long as the cell body is wide.
