Golgi tendon organ
Golgi tendon organ A Golgi tendon organ is a sensory structure in the tendons at the ends of muscles that detects muscle tension during contraction.
A Golgi tendon organ is a sensory structure in the tendons at the ends of muscles that detects muscle tension during contraction. When tension rises, it helps limit further contraction through spinal cord pathways, which protects the muscle from damage; unlike a muscle spindle, it signals tension rather than muscle length.
