What is a proprioceptor?

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

Answer: (D)

Proprioceptors are sensors that monitor the position and movement of the body. They reside in muscles (muscle spindles), tendons (Golgi tendon organs), and joints, providing continuous feedback about muscle length, tension, and joint angles. This information creates the sense of kinesthesia, letting the brain know where limbs are in space and how they’re moving, even without visual input. This system works together with vision and the vestibular apparatus to coordinate smooth, accurate movement. Exteroceptors detect external stimuli such as touch, temperature, or vision, while interoceptors monitor internal bodily states like hunger or gut stretch. Baroreceptors are a specific type of interoceptor that senses blood pressure in blood vessels. Proprioceptors are distinct because their primary role is sensing the body’s own position and movement.
