Multipolar neuron

A Multipolar neuron (pronounced: mul-ti-po-lar neu-ron) is a type of neuron that possesses a single (usually long) axon and many dendrites, allowing for the integration of a great deal of information from other neurons. These neurons are commonly found in the central nervous system.

Etymology

The term "Multipolar neuron" is derived from the Latin words 'multi' meaning 'many', and 'polar' meaning 'having poles'. The term 'neuron' is derived from the Greek word 'neuron' meaning 'nerve'.

Structure

Multipolar neurons are the most common type of neuron in the human brain. They have a single axon and multiple dendrites, which are short, branched extensions of the neuron that receive signals from other neurons. The axon is a long projection that transmits signals to other neurons or to effector cells.

Function

Multipolar neurons are involved in many functions, including the relay of sensory information, the control of muscles, and the integration of information from different sources. They are also involved in higher cognitive functions such as learning and memory.
