Which receptor type detects limb position and movement?

• A. Proprioceptor
• B. Exteroceptor
• C. Interoceptor
• D. Nociceptor

Answer: (A)

Detecting limb position and movement is the job of proprioceptors. These receptors monitor information about body position and motion from muscles, tendons, and joints. Muscle spindles sense how much and how quickly a muscle is stretched, Golgi tendon organs sense muscle tension, and joint receptors provide data on joint angle and movement. This proprioceptive feedback lets the brain know where the limbs are in space and how they’re moving, even without vision, which is crucial for coordinated movement and balance. Exteroceptors sense external stimuli like touch and temperature on the skin, interoceptors monitor internal bodily states, and nociceptors signal tissue damage. So proprioceptors specifically report limb position and movement.
