Multipolar neuron

Recommended video: Neurons [11:24]
Neurons are the basic building blocks of the nervous system.

The term 'multipolar neuron' represents one of the several classifications of neurons in the nervous system based on their morphological appearance, which refers to how the axon and dendrites are organized in relation to the cell body. Other types include bipolar, unipolar and pseudounipolar neurons.

Multipolar neurons are typically characterized by a single axon and two or more dendrites arising from the cell body. Functionally, the dendrites serve as receptors, while the axon is the primary conducting pathway for electrical impulses.

They are the most common form of neurons throughout the nervous system and include all motor neurons that innervate skeletal muscles, as well as neurons of the autonomic nervous system (ANS) and central nervous system (CNS) interneurons.

Multipolar neurons can be further grouped into several subtypes, with pyramidal, stellate, Purkinje and granule cells among the most common.

Terminology English: Multipolar neuron
