| coracobrachial muscle | <anatomy> Relating to the coracoid process of the scapula and the arm. <muscle> Origin, coracoid process of scapula; insertion, middle of medial border of humerus; action, adducts and flexes the arm; resists downward dislocation of shoulder joint; nerve supply, musculocutaneous. See: coracobrachial bursa. Synonym: musculus coracobrachialis, Casser's perforated muscle, coracobrachial muscle. (05 Mar 2000) |

| corrugator cutis muscle of anus | Smooth muscle fibres radiating from the anal opening superficial to the external sphincter. Synonym: musculus corrugator cutis ani. (05 Mar 2000) |
| corrugator muscle | <anatomy, muscle> Origin, from orbital portion of musculus orbicularis oculi and nasal prominence; insertion, skin of eyebrow; action, draws medial end of eyebrow downward and wrinkles forehead vertically; nerve supply, facial. Synonym: musculus corrugator supercilii, Coiter's muscle, corrugator muscle, wrinkler muscle of eyebrow. (05 Mar 2000) |
| cowl muscle | <anatomy, muscle> Origin, medial third of superior nuchal line, external occipital protuberance, ligamentum nuchae, spinous processes of seventh cervical and the thoracic vertebrae and corresponding supraspinous ligaments; insertion, lateral third of posterior surface of clavicle, anterior side of acromion, and upper and medial border of the spine of the scapula; action, when scapulae are fixed, portions of muscle can act independently: cervical portion elevates scapula, thoracic portion contributes to depression of scapula; upper and lowermost portions act simultaneously to rotate glenoid fossa superiorly; when the entire muscle and especially middle part contracts, the scapulae retract; draws head to one side or backward; nerve supply, motor by accessory, sensory by cervical plexus. Synonym: musculus trapezius, cowl muscle, trapezius. (05 Mar 2000) |

| posterior tibial muscle | <anatomy, muscle> Origin, soleal line and posterior surface of tibia, the head and shaft of the fibula between the medial crest and interosseous border, and the posterior surface of interosseous membrane; insertion, navicular, three cuneiform, cuboid, and second, third, and fourth metatarsal bones; action, plantar flexion and inversion of foot; nerve supply, tibial.
