Proprioception is defined as which of the following?

• A. Ability to detect movement.
• B. Awareness of body motion in space.
• C. Sense of touch at joints.
• D. Determining one's position in space.

Answer: (D)

Proprioception is the internal sense that tells you where your body parts are in relation to each other and in space without looking. Receptors in muscles, tendons, and joints provide information about limb position and movement, and the brain uses this to guide coordinated action. The strongest definition here is determining one's position in space, because it directly captures the sense of where the body is located without relying on vision. The other ideas refer to related but distinct senses: sensing motion (kinesthesia) and sensing touch at joints (cutaneous/proprioceptive mix), rather than the position itself.
