Which of the Following Increases the Force of Contraction of a Whole

Question

Which of the following increases the force of contraction of a whole muscle?
A) Twitch
B) Contracture
C) Ossification
D) Recruitment

Accepted Answer

Recruitment refers to the process of activating more motor units within a muscle to increase the force of contraction. This is the mechanism by which muscles can produce stronger contractions without necessarily increasing the frequency of nerve impulses to each motor unit. Twitch refers to a single, brief contraction of a muscle fiber, and contracture refers to a condition in which a muscle becomes abnormally contracted and cannot relax. Ossification refers to the process of bone formation.
