"unipolar neuron" 的定义和意义

What is a "unipolar neuron"?

A unipolar neuron is a specialized nerve cell that plays a crucial role in the transmission of sensory information in the body. It has a single projection called a neurite, which functions both as an axon and a dendrite. The neurite extends from the cell body and branches out to receive sensory signals from various sources, such as touch, pressure, or temperature receptors. These signals are then transmitted to the central nervous system for processing and interpretation. The unique structure of the unipolar neuron allows for efficient and rapid transmission of sensory information, making it an essential component of the body's sensory system.
