What happens during coactivation?

Question

Quizplus · Accepted Answer

Coactivation refers to the simultaneous activation of both gamma motor-neurons and alpha motor-neurons to a skeletal muscle. This allows for fine control of muscle contraction and helps to maintain muscle tone. Option A is incorrect as not all muscle fibres need to be activated at the same time. Option C is incorrect as cross-bridges are part of the contractile machinery within a muscle cell, not the neural control system. Option D is incorrect as it refers specifically to the activation of sensory receptors within a muscle spindle, not the overall neural control of the muscle.
