Detailed explanation-1: -Multipolar neurons are the most common type of neurons in the human body. They are present throughout a person’s CNS, including the brain and associated nerves in the autonomic nervous system. 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.
