Which mechanoreceptor senses changes in tension?

Explanation:
Golgi tendon organs are the mechanoreceptors that monitor muscle tension. Located at the muscle–tendon junction, they respond when force in the tendon increases and send Ib afferent signals to the spinal cord. This triggers autogenic inhibition, reducing muscle activation to protect the tendon from injury. Muscle spindles, by contrast, detect changes in muscle length and velocity of stretch, not tension. Proprioception refers to the overall sense of body position and movement, drawn from multiple receptors. So, for sensing changes in tension specifically, the Golgi tendon organs fit best.
