Definitions:

Muscle Fibers

Muscle fibers are the individual contractile units of muscle tissue, made up of myofibrils and encapsulated in a sarcolemma, that facilitate body movements through contraction and relaxation.

Skeletal Muscle

A type of striated muscle tissue attached to bones, responsible for voluntary movements of the body.

Motor Neurons

Nerve cells that originate in the brain or spinal cord and transmit signals to muscles, inducing movement.

Motor Unit Recruitment

Motor unit recruitment involves the activation of additional motor units to increase the strength of a muscular contraction.
