Which receptors are responsible for sensing body position in relation to the environment and are located in tendons, muscles, and joints?

• A. Proprioceptors
• B. Nociceptors
• C. Thermoreceptors
• D. Nerve Endings

Answer: (A)

Proprioceptors are specialized sensors that tell the brain where your body parts are in space and how they’re moving. They’re located in muscles (muscle spindles), tendons (Golgi tendon organs), and joints, and they detect mechanical changes such as muscle stretch, tendon tension, and joint angles. This feedback lets you sense limb position and movement even when you can’t see your body, supporting balance, posture, and coordinated actions.

Nociceptors respond to potentially damaging stimuli and give rise to the sensation of pain. Thermoreceptors detect temperature changes. Nerve endings is a broad term that doesn’t specifically refer to sensing body position.
