Define: striations
Muscle fibres join other parallel fibres.
True OR False: smooth muscle is controlled by the autonomic nervous system
True
Define: peristalsis
Rhythmic contractions that help move food along the digestive tract
Define: sarcolemma
Cell membrane of muscle cell
Define: myofibril
The actin and myosin give skeletal muscle it’s striated appearance
Define: ATP
Adenosine triphosphate
Define: abductor
Moves limb away from medial plane
Define: adductor
Moves limb towards medial plane
Define: agonist
Movement of muscles that cause the prime movement
Define: antagonist
Muscles responsible for opposite action
