D) contraction; contraction

Question

Quizplus · Accepted Answer

The activity of a muscle spindle is to sense changes in muscle length and send signals to the central nervous system, which then causes the muscle to contract. In contrast, the activity of the Golgi tendon organ is to sense changes in muscle tension and send signals to the central nervous system, which then inhibits the contraction of the muscle. Therefore, the activity of the muscle spindle is related to contraction while the activity of the Golgi tendon organ is related to the inhibition of contraction, making choice A the correct answer.

Activity of a Muscle Spindle Is to ____ as Activity
