A diagram showing the bipolar neuron.

A bipolar neuron or bipolar cell is a type of neuron which has two extensions. These neurons are specialized sensory neurons for the transmission of special senses. As such, they are part of the sensory system.

Structure

Bipolar neurons have two extensions from the cell body (soma). These extensions are the axon and dendrite. The axon carries nerve signals away from the soma, and the dendrites bring signals to the soma.

Function

Bipolar neurons are specialized sensory neurons and they play a crucial role in conveying information about the environment. The human sensory system relies on bipolar neurons to transmit information about sight, smell, and hearing.

Clinical significance

Bipolar neurons, like all neurons, can be affected by a variety of neurological disorders. These include Alzheimer's disease, Parkinson's disease, and other neurodegenerative diseases.
