What Is a Bipolar Neuron?
A bipolar neuron is a neuron with two independent processes. One protrusion from each end of the cell body: one is a dendrite, which is distributed to the surroundings; one is an axon, which extends to the center. Only found in the vestibular ganglia, cochlear ganglia, olfactory receptors and retina of the auditory nerve.

- In the retina, connect optic cells and ganglion cells, and play a longitudinal communication role. At this time, its cell body is located in the inner core layer; the outer dendrites extend into the outer reticulum layer, forming synaptic connections with the medial processes of the optic cells (rod cells, cone cells); Dendritic cells of synovial cells form synaptic connections. In the retina, pygmy bipolar cells, rod-shaped bipolar cells, and flat bipolar cells can be classified according to their morphology and axonal connections. Dendrites of dwarf bipolar cells form synapses with only one cone cell, and their axons only synapse with dendrites of one ganglion cell; the dendrites of the latter two can interact with multiple cone cells or rod cells Synapses are formed and the excitatory transmitters released are mainly acidic amino acids (L-glutamic acid, I. aspartic acid). In the olfactory mucosa of the nasal cavity, the olfactory cells are called slender spindles, which are sensory neurons existing in the epithelium.
