Detailed explanation-1: -A bipolar neuron, or bipolar cell, is a type of neuron that has two extensions (one axon and one dendrite). Many bipolar cells are specialized sensory neurons for the transmission of sense. As such, they are part of the sensory pathways for smell, sight, taste, hearing, touch, balance and proprioception.
Detailed explanation-2: -Dendrites. Dendrites and axons are cytoplasmic extensions, or processes, that project from the cell body. They are sometimes referred to as fibers. Dendrites are usually, but not always, short and branching, which increases their surface area to receive signals from other neurons.
Detailed explanation-3: -Bipolar neurons are found in the retina of the eye, roof of the nasal cavity, and inner ear. They are always sensory and carry information about vision, olfaction, equilibrium, and hearing.
