What is a bipolar neuron?

Bipolar neuron is a sensory nerve cell that has two processes ranging from the body of the cell. These sensory neurons, classified with the nervous system, detect and change signal changes in the system. Bipolar neuron usually communicates with other cells in the nervous system through chemical signaling and is an electrically exciting cell. The presence of two processes, Axon and Dendrite that are on the opposite sides is what neuron does bipolar. Each of them deals with the senses of the body. In the eyes there are retinal cells and olfactory epithelial cells are located in the nasal cavity. Kochlear ganglia is part of a nerve that transmits signals from the inner ear to the brain. Vestibular ganglie is part of the vestibular system that regulates the body's balance. For example, retinal cells are a group of bipolar neurons that seem to be round when viewed. In this area of ​​the nervous system, sensory neurons are classified as "ON" or "OFF" bipolar cells. While "on" bipolar neurons are excited by the reaction of glutamate to increased light exposure ", bipolar cells are not exposed to large volumes of light and therefore do not receive such chemical signaling.

Bipolar neuron "he" usually responds to the release of glutamate by expanding in the light. Neuron is considered "off" when light exposure is minimized and the retina returns to its normal size. While "he", bipolar neurons protect the retina from channels permeable in cations.

also classified as bipolar neuron, olfactory cell houses rounded cores and contain small vesicular structures. The olfactory cells pass between support cells near the surface of the nervous system. Dendrites extend and create rods that help to form a layer of liquid from Bowman Glands. Dendritation processes that work properly prevent olfactory failures.
