Describe the function of the muscle spindle and golgi tendon organ
What will be an ideal response?
Muscle spindles detect changes in the length of the muscle. They consist of a collection of specialized muscle fibers called intrafusal fibers. At the center of these fibers is a non-contractile element innervated by afferent sensory neurons. These fibers lie within spindle-shaped connective tissue capsules that lie in parallel to the extrafusal fibers. The sensory fibers are activated when the muscle is stretched. Golgi tendon organs are found in the tendons of muscles and respond to changes in muscle tension. Golgi tendon organs consist of afferent nerve endings intertwined with bundles of connective tissue fibers that make up the tendon.
