Sensory fibers are specialized nerve fibers that transmit sensory information from various parts of the body to the central nervous system. They play a crucial role in how we perceive our environment, carrying signals related to touch, pain, temperature, and other sensations. These fibers are part of the peripheral nervous system and are essential for our ability to respond to stimuli. There are different types of sensory fibers, including A-delta fibers and C fibers, which vary in their speed and function. A-delta fibers are responsible for quick, sharp pain sensations, while C fibers transmit slower, dull pain. Together, they help the body process and react to sensory experiences effectively.
