Document Summary

Epicranius (frontalis & occipitalis) wrinkles forehead/elevates eyebrow. Suprahyoid (mylohyoid, stylohyoid, digastric) elevates hyoid/mouth floor, elevates/retracts tongue, depresses mandible. Infrahyoid (omohyoid, thyrohyoid, sternohyoid, sternothyroid) depress hyoid. Pharyngeal constrictors (superior, middle and inferior) swallowing. Sternocleidomastoid, splenius capitis, splenius cervicis all lateral flexion (flex neck, extend head, extend neck) Erector spinae (ilicostalis, longissimus, spinalis) posture and extension. Quadratus lumborum back muscle, can do lateral flexion or extension of vertebral column (lumbar) Diaphragm circular muscle flattens & expands thorax in inspiration (linked to external) Internal/external oblique, rectus abdominis lateral flexion and rotation. Pectoralis minor draws scapula to front & rib cage up during forced inhalation. Levator scapulae & rhomboid minor: elevate and adduct scapula. Subclavius, rhomboid major: depresses pectoral girdle & stabilize scapula. Deltoid, supraspinatus extends, flexes shoulder joint, abducts shoulder joint. Pectoralis major, coracobrachialis rotates shoulder joint, flexes, adducts. Superficial: flexor digitorum superficialis (digits too), flexor carpi ulnaris (adducts), palmaris longus,
