Which statement best describes the nerves contained in the joint capsule that monitor joint position and stretch?

• A. Motor nerves
• B. Capillary beds produce synovial fluid
• C. Autonomic nerves
• D. Sensory and pain nerves in capsule to monitor joint position and stretch

Answer: (D)

The nerves inside the joint capsule are primarily sensory, providing proprioceptive feedback about the joint. They include mechanoreceptors that detect how far the joint is bent and how quickly it’s moving, giving the brain information on joint position and stretch. Some endings are free nerve endings that signal pain when the capsule is irritated or overstretched. This combination of sensory and nociceptive fibers explains how the capsule monitors position, movement, and protection against injury. Motor nerves, capillary action for synovial fluid, or autonomic fibers don’t describe this proprioceptive signaling as accurately.
