Which of the following is a shared characteristic of both the Golgi tendon organ

Question

Which of the following is a shared characteristic of both the Golgi tendon organ and annulospiral ending of the muscle spindle apparatus

Spiralling around collagen or extrafusal muscle fibers brings about depolarization.

Muscle tension is indirectly transmitted as stretch to sensory receptors.

Free nerve endings detect the extracellular surface chemicals and convert the signal into sensory information.

External stretch, like the knee jerk reflex, can only stimulate the Golgi tendon organ.

Spiralling around collagen or extrafusal muscle fibers brings about depolarization.

Explanation / Answer

Muscle spindles are sensory receptors in muscles that detect change in length of muscles. Golgi tendon organ occurs in tendons of skeletal muscles that can detect changes in muscle tension. The annulospiral endins of muscle spindle apparatus are wrapped in the central part of intrafusal fibers to detect the changes in length of muscle fibers during stretching. The afferent fiber endings of Golgi tendon organs occur entwined within the connective tissue and are stretched causing the afferent fibers to fire. Therefore, both the muscle spindles and Golgi tendon organ commonly detect the muscle tension and transmit the stretch response to sensory receptors. Option 2 is correct.
