Which sensory nerve endings are located in the muscles, tendons and joints to provide information about movements and body position?

• A. Proprioceptors
• B. Baroreceptors
• C. Chemoreceptors
• D. Adrenaline

Answer: (A)

Proprioception is about sensing where our body parts are and how they’re moving. This relies on proprioceptors, the sensory nerve endings located in muscles, tendons and joints. They detect changes in muscle length (via muscle spindles), muscle tension (via Golgi tendon organs), and joint movement (via joint receptors). The signals from these receptors travel to the brain, giving information about limb position, movement speed, and overall body orientation, which is why we can coordinate actions and maintain balance without looking.

Baroreceptors monitor blood pressure, chemoreceptors sense chemical changes in the blood (like O2, CO2, pH), and adrenaline is a hormone, not a sensory nerve ending. So the sensors in muscles, tendons, and joints that provide movement and position information are proprioceptors.
