D)Recruitment

Question

Quizplus · Accepted Answer

Recruitment refers to the activation of more motor units within a muscle. This allows for more muscle fibers to contract, increasing the force of contraction for the whole muscle. A twitch is a single, brief contraction and does not increase force. A contracture refers to a permanent shortening of muscle fibers due to inactivity or scarring and does not increase force. Ossification refers to the formation of bone tissue and is not relevant to muscle contraction.
