Question

muscles used for delicate, finely controlled movements have smaller motor units than muscles used for high power activities. true or false true false

Explanation:

A motor unit consists of a motor neuron and the muscle fibers it innervates. Muscles for delicate movements (e.g., eye muscles) have smaller motor units (fewer muscle fibers per motor neuron) for precise control. Muscles for high - power activities (e.g., thigh muscles) have larger motor units (more muscle fibers per motor neuron) to generate greater force.

Answer:

True
