the actual group of muscle fibers in a muscle innervated by a single motor neuron is referred to as what?
a.) cross bridge
b.) muscle tension
c.) motor unit
d.) fascicle

Explanation:

A motor unit is defined as a single motor neuron and all the muscle fibers it innervates. A cross - bridge is a part of the muscle contraction mechanism (interaction between actin and myosin). Muscle tension is the force exerted by a muscle. A fascicle is a bundle of muscle fibers.
