A bipolar neuron is a nerve cell made of two extensions with one axon and one dendritic tree.
The axon is the long, thin part of the neuron.
The dendrites are the neuron's input sites and resemble branches from a tree.
The axon carries information from the dendrites to the terminal buttons that are the output for the neuron.
Bipolar neurons are specialized sensory neurons that are used to transmit information about sight, smell, and taste. They are also located in the vestibular nerve and assist in sensations of hearing, balance, and motion perception.
