Bipolar neurons

Definition

Bipolar neurons are specialized sensory neurons with one axon and one dendrite extending from opposite ends of the cell body. They are involved in transmitting sensory information such as taste and smell to the central nervous system.

5 Must Know Facts For Your Next Test

1. 1. Bipolar neurons are found in sensory pathways including those for taste (gustation) and smell (olfaction).
2. 2. These neurons play a crucial role in converting chemical signals from stimuli into electrical signals sent to the brain.
3. 3. In the olfactory system, bipolar neurons connect directly to olfactory receptor cells and transmit signals to the olfactory bulb.
4. 4. Each bipolar neuron is typically associated with a specific type of sensory receptor cell.
5. 5. Damage or dysfunction of bipolar neurons can result in impairments in taste and smell perception.
