The process of engaging more motor units to increase the strength of a muscle contraction is called __________.
A) wave summation
B) recruitment
C) temporal summation
D) incomplete tetanus
E) complete tetanus

Question

Quizplus · Accepted Answer

Recruitment is the process of activating more motor units in a muscle to increase the strength of a contraction. This allows for greater force to be generated by the muscle. Wave summation refers to the increase in strength of a muscle contraction due to the rapid stimulation of muscle fibers by a nerve impulse. Temporal summation refers to the increase in strength of a muscle contraction due to the increased frequency of nerve impulses. Incomplete tetanus is a sustained contraction that is not at maximum strength, while complete tetanus is a sustained contraction at maximum strength.
