Proprioception refers to which aspect of sensation?

• A. Vibration
• B. Temperature
• C. Pain
• D. Position sense and kinesthesia

Answer: (D)

Proprioception is the sense of body position and movement. It comes from proprioceptors in muscles, tendons, and joints that relay information about limb orientation and motion to the brain, helping you know where your limbs are even with your eyes closed. This is different from vibration sense (mediated mainly by skin mechanoreceptors like Pacinian corpuscles), temperature (thermoreceptors), and pain (nociceptors). Proprioception underpins coordinated movement and balance; when it’s impaired, you see clumsy, ataxic movements and trouble judging limb position, which clinicians often test by asking you to identify the position of a finger or toe with your eyes closed.
