Document Summary

Axial muscles: muscles of the head & neck ch 11a introduction. Axial muscles have both their attachments on parts of the axial skeleton. Currently: superior & inferior attachments or proximal & distal attachments . Functions of the axial muscles: support the head & spinal column, used in facial expression, chewing & swallowing, aid in breathing, support & protect abdominal & pelvic organs. Axial muscles are organized into 5 groups based on their location: Pelvic floor muscles of the head & neck. Must attach to skull or hyoid bone muscles of facial expression. Attach to superficial fascia or to skull bones. Since fascia is connected to skin, contraction moves skin. Platysma surface anatomy of some facial muscles e- muscles of mastication. Elevates & protracts mandible muscles that move the head & neck. Anterolateral neck muscles: flex the head and/or neck. Posterior neck muscles: extend head and/or neck. Arise from: vertebrae, thoracic cage, pectoral girdle. Attach to cranial bones anterolateral neck muscles.
