Pseudounipolar neuron

Pseudounipolar neurons are a type of neuron that have two axons instead of an axon and dendrite. These neurons are found in the sensory ganglia of the peripheral nervous system and are responsible for transmitting sensory information from the body to the central nervous system.

Structure

Pseudounipolar neurons have a single process that extends from the cell body and divides into two branches. One branch extends to the periphery and functions as a dendrite to receive sensory information. The other branch extends to the central nervous system and functions as an axon to transmit this information.

Function

The primary function of pseudounipolar neurons is to transmit sensory information from the body to the central nervous system. This information includes touch, temperature, pain, and proprioceptive signals.

Clinical significance

Damage to pseudounipolar neurons can result in sensory deficits, including loss of touch, temperature, and pain sensation. This can occur as a result of trauma, infection, or diseases such as diabetes and multiple sclerosis.
