Document Summary
Explain how muscles are described according to their location and cooperative function. Explain what is meant by synergistic and antagonistic muscle groups. Locate the major muscles of the axial skeleton. Use the name of muscle to help identify and remember its orientation, location, appearance and action. Predict the actions of a muscle on the basis of its name, origin and insertion. Muscles of the head and neck: facial muscles sternocleidomastoid muscle. List the names and functions of muscles of respiration. We generally speak of muscles having an origin (the attachment where the muscle starts) and an insertion (the attachment where the muscle ends) If the muscle extends from a broad aponeurosis (wide layer of tendons) to a narrow tendon: aponeurosis = origin tendon = insertion. If there are several tendons at one end and only one at the other: multiple = origins single = insertion. Remember action words from unit 1 (flexion, extension, inversion, eversion, adduction, abduction)
