How does a sensory nerve function?

Sensory nerves are specialized components of the nervous system responsible for transmitting sensory information from various parts of the body to the central nervous system, mainly the brain. The primary function of sensory nerves is to detect stimuli such as touch, temperature, pain, and proprioception (the sense of body position), particularly from muscles, skin, and internal organs.

In the context of the correct answer, sensory nerves play a crucial role in sensing conditions in muscles, such as stretch or tension, and then relaying that information to the brain for processing. This communication allows the brain to interpret the body’s state and make necessary adjustments, whether it be in response to physical activity, muscle fatigue, or any injury. Thus, the chosen answer accurately captures the essence of a sensory nerve's function—detecting sensory input from the muscles and transmitting that information to the brain for appropriate responses.
