Sensory nerve fibers

Sensory nerve fibers are specialized parts of your nervous system that detect stimuli such as touch, temperature, pain, and pressure from your body and environment. They transmit signals from sensory receptors in your skin, muscles, and organs to your brain and spinal cord, allowing you to perceive and respond to sensations. These fibers vary in size and function—some quickly send sharp pain signals, while others provide ongoing pressure or temperature information. Overall, sensory nerve fibers are essential for your awareness of the world and maintaining your body's safety and function.
