Muscle Histology, EMG, and Fatigue

the combination of an individual motor neuron and all of the muscle fibers that it innervates

A body part is moved and the muscle fibers shorten or lengthen

The muscle contracts but your joints do not move and muscle fibers maintain a constant length

aka "prime movers", it is the primary muscle responsible for generating movement through their contraction

control (or oppose) specific movement and return the agonist to its initial position after contraction ends

contraction of an agonist muscle leads to minor activity in the antagonist muscle

state of physiological inability to contract effectively

What does an EMG record?

Physiological factors of muscle fatigue?

Other factors of muscle fatigue?
