Detailed explanation-1: -Motor neurons have the most common type of ‘body plan’ for a nerve cell-they are multipolar, each with one axon and several dendrites.
Detailed explanation-2: -A multipolar neuron has the highest number of structures extending from the cell body.
Detailed explanation-3: -Although unipolar and bipolar neurons are present in the nervous system, most neurons are multipolar. Neurons have a long cell process called an axon. This can extend for many centimeters. Axons transmit impulses to other neurons.
Detailed explanation-4: -Multipolar neurons: These neurons are able to receive impulses from multiple neurons via dendrites. The dendrites transmit the signals through the neuron via an electrical signal that is spread down the axon. Bipolar neurons: These neurons send signals and receive information from the world.
