This type of muscle fiber is a fast-twitch muscle and its cells contain few mitochondria.
White
What are the two compartments of the upper arm?
anterior and posterior
This type of muscle makes up the mass of the heart and is not under voluntary control.
Cardiac muscle

Quadriceps
This muscle rotates the forearm and flexes the elbow.
biceps

Hamstring
This muscle helps straighten the arm after being flexed by the bicep.
tricep
Alternating light and dark bands on skeletal muscles are called this.
Striations
Skeletal muscle cells are filled with tightly packed filament bundles called this.
Myofibrils
What are the two types of muscle fibers?
Red and white
Name one of the three muscles in the hamstring.
Bicep fermoris, semimembranosus, semitendinosus
This term refers to moving a body part toward the center of your body.
adduction
Another name for skeletal muscle cells.
muscle fibers
Each myofibril contains thick filaments of a protein called this.
Myosin
This type of muscle fiber contains many mitochondria and has a generous supply of oxygen.
This tendon stores energy needed for running and jumping.
This muscle flexes and adducts your wrist.
flexor carpi ulnaris
