| masseter muscle | <anatomy> A masticatory muscle whose action is closing the jaws. (12 Dec 1998) |
| rectouterine muscle | <anatomy> A band of fibrous tissue and smooth muscle fibres passing between the cervix of the uterus and the rectum in the rectouterine fold, on either side. Synonym: musculus rectouterinus. (05 Mar 2000) |
| rectovesicalis muscle | <anatomy> Smooth muscle fibres in the sacrogenital fold in the male; they correspond to rectouterinus musculus. Synonym: musculus rectovesicalis, rectovesical muscle. (05 Mar 2000) |

| rectus abdominis muscle | <anatomy> Muscle of ventral abdominal wall, flanking the linea alba, and characterised by tendinous intersections separating its length into multiple bellies; origin, crest and symphysis of the pubis; insertion, xiphoid process and fifth to seventh costal cartilages; action, flexes lumbar vertebral column, draws thorax downward toward pubis; nerve supply, thoracoabdominal nerves. Synonym: musculus rectus abdominis, rectus muscle of abdomen. (05 Mar 2000) |

| recurrent laryngeal nerve | <anatomy, nerve> A branch of a nerve (the vagus nerve) that comes down the neck and turns back ( recurs ) to supply the larynx (the voice box ). (12 Dec 1998) |
| recurrent meningeal nerve | <anatomy, nerve> Meningeal branches of 1) mandibular, 2) maxillary, 3) ophthalmic, and 4) spinal nerves. (05 Mar 2000) |

| masticator nerve | <anatomy, nerve> The smaller root of the trigeminal nerve, composed of fibres originating from the trigeminal motor nucleus and emerging from the pons medial to the much larger sensory root, to join the mandibular nerve; it carries motor and proprioceptive fibres to the muscles derived from the first bronchial (mandibular) arch, including the four muscles of mastication, plus the mylohyoid, anterior belly of the digastric, and the tensores tympani and veli palati. Synonym: radix motoria nervi trigemini, masticator nerve, portio minor nervi trigemini. (05 Mar 2000) |
| red muscle | Slow-twitch muscle in which small dark "red" muscle fibres predominate; myoglobin is abundant and great numbers of mitochondria occur, characterised by slow, sustained (tonic) contraction. Contrast with white muscle. (05 Mar 2000) |
| Casser's perforated 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) |
