Multiple Choice

Which of these mechanisms causes golgi tendon organs to start firing action potentials?

As the muscle contracts, collagen fibers 'squeeze' the nerve endings of the golgi tendon organ.

As the muscle relaxes, collagen fibers 'squeeze' the nerve endings of the golgi tendon organ.

As the muscle contracts, free nerve endings in the golgi tendon organ are compressed by muscle fibers.

As the muscle stretches, free nerve endings in the golgi tendon organ are compressed by muscle fibers.

Verified step by step guidance

Understand the role of Golgi tendon organs: They are sensory receptors located at the junction of muscles and tendons, responsible for detecting changes in muscle tension.

Identify the structure of Golgi tendon organs: They contain nerve endings interwoven with collagen fibers within the tendon.

Consider the effect of muscle contraction: When a muscle contracts, it increases tension in the tendon, which can affect the nerve endings in the Golgi tendon organ.

Analyze how tension affects the nerve endings: As tension increases, the collagen fibers within the Golgi tendon organ compress the nerve endings, leading to the generation of action potentials.

Evaluate the options: The correct mechanism involves the compression of nerve endings by collagen fibers as a result of increased tension from muscle contraction.
