Answer:
Biceps
Abductor
Internal
Rectus
Explanation:
Biceps mean that the muscle attaches to two origins. The "bi" part means "two", so tri-ceps will have 3 origins.
Abductor tells what action the muscle does. Abduction is the movement that pulls away from the body. Its the opposite of induction.
Internal give location of the muscle. Internal mean it is in a deeper layer while external muscle will be at a higher layer.
Rectus mean straight. It means the muscle fiber direction is straight.
