Which of the following does golgi tendon organ detect?
(A) Muscle Tension (B) Dynamic muscle length (C) Static muscle length (D) Muscle action
(A) Ans. A. Muscle Tension(Ref.: Ganong 25/e p232; Guyton 13/e p697, 701).Golgi tendon organ senses muscle tension.The Golgi organ (also called Golgi tendon organ, GTO, tendon organ, neurotendinous organ or neurotendinous spindle) senses changes in muscle tension.It is a proprioceptive sensory receptor organ that is at the origin and inseion of skeletal muscle fibers into the tendons of skeletal muscle.It provides the sensory component of the Golgi tendon reflex.
