What is the function of the three neurons? (bipolar, unipolar, multipolar)
A bipolar cell is a type of neuron which has two extensions. Bipolar cells are specialized sensory neurons for the transmission of special senses. As such, they are part of the sensory pathways for smell, sight, taste, hearing and vestibular functions They are found in the vestibulocochlear nerve, but referrence to bipolar neurons is usually to cells in the retina.
A unipolar neuron is a type of neuron in which only one protoplasmic process (neurite) extends from the cell body. Most neurons are multipolar, generating several dendrites and an axon: unipolar neurons are exceptions to this rule. These would be primary sensory neurons such as the ones found in the dorsal root ganglion.
A multipolar neuron 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 dendritic branches can also emerge from the nerve cell body. Multipolar neurons constitute the majority of neurons in the brain and include motor neurons and interneurons.
