Ch8 Orthopedics (Muscle) Gen

Origin

beginning of a muscle

• Site where a tendon attaches to a stationary bone where it doesn’t move when the muscle contracts

insertion

end of a muscle

• where a tendon attaches to the bone that moves when the muscle contracts

belly

part of the muscle with the greatest mas

fascicles

a bundle of muscle fibers that are enclosed by a sheath of connective tissue called the perimysium

myofibirils

make up muscle fibers and contain thin actin strands and thick myosin strands

Antagonistic

One muscle contracts and a second muscle relaxes to allow controlled movement

Synergism

One muscle contracts and another nearby muscle contracts to produce the same but greater combined movement

Eversion

Turning a body part outward sideways (Ankle out)

Inversion

Turning a body part inward sideways (ankle in)
