A multipolar neuron has the highest number of structures extending from the cell body.

Detailed explanation-2: -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-3: -Multipolar neurons constitute the majority of neurons in the central nervous system. They include motor neurons and interneurons/relaying neurons are most commonly found in the cortex of the brain and the spinal cord. Peripherally, multipolar neurons are found in autonomic ganglia.
