The activation of increasing numbers of motor units is known as ________.
A) motor unit recruitment
B) muscle fatigue
C) muscle tension
D) threshold stimulus

Question

Quizplus · Accepted Answer

Motor unit recruitment refers to the process by which increasing numbers of motor units are activated in order to generate increasing levels of muscle tension. This process is necessary for producing stronger muscle contractions. Muscle fatigue refers to the decline in muscle performance that occurs as a result of prolonged or intense activity. Muscle tension refers to the force that is generated by a muscle when it contracts. Threshold stimulus refers to the minimum level of stimulation required to elicit a response in a muscle fiber or neuron.
