| transverse crest of internal acoustic meatus | A horizontal ridge that divides the fundus of the internal acoustic meatus into a superior and an inferior area. In the former are the introitus of the facial canal and openings for the branches of the vestibular nerve to the utricle and to the ampullae of the anterior and lateral saemicircular canals. In the latter are openings for the cochlear nerve, and for branches of the vestibular nerve to the saccule and to the ampulla of the posterior saemicircular canal. Synonym: crista transversa, falciform crest, transverse crest. (05 Mar 2000) |

| lateral costal branch of internal thoracic artery | <anatomy, artery> A variable branch of internal thoracic artery that runs lateral and parallel to the internal thoracic artery on the deep surface of the rib cage; anastomosis: posterior intercostal arteries. Synonym: ramus costalis lateralis arteriae thoracicae internae. (05 Mar 2000) |
| fracture fixation, internal | The use of internal devices (metal plates, nails, rods, etc.) to hold the position of a fracture in proper alignment. (12 Dec 1998) |
| fundus of internal acoustic meatus | The thin cribriform plate of bone separating the cochlea and vestibule from the internal acoustic meatus; a transverse crest divides it into two regions; in the superior region are located the area nervi facialis and the area vestibularis superior; in the inferior region are located the area cochleae, area vestibularis inferior, and foramen singulare. Synonym: fundus meatus acustici interni, fundus of internal auditory meatus. (05 Mar 2000) |

| anal fascia | The fascia that covers the inferior aspect of the levator ani and coccygeus muscles. Synonym: fascia diaphragmatis pelvis inferior, anal fascia. (05 Mar 2000) |
| antebrachial fascia | It is continuous with the brachial fascia; in the region of the wrist it forms two thickened bands, the extensor and flexor retinacula. Synonym: fascia antebrachii, deep fascia of forearm, fascia of forearm. (05 Mar 2000) |
| arcus tendineus of obturator fascia | <anatomy> A thickened portion of the obturator fascia that extends in an arching line from the pubis posteriorly to the ischial spine and gives origin to part of the levator ani muscle. Synonym: arcus tendineus musculi levatoris ani, arcus tendineus of obturator fascia. (05 Mar 2000) |
| axillary fascia | The fascia that forms the floor of the axilla. It is continuous with the pectoral and clavipectoral fascia anteriorly, with the brachial fascia laterally, and with the fascia of the latissimus dorsi and serratus anterior muscles posteriorly and medially. Synonym: fascia axillaris. (05 Mar 2000) |
| bicipital fascia | Aponeurosis bicipitalis, radiating fibres from the tendon of insertion of the biceps which form a triangular band passing obliquely across the hollow of the elbow to the ulnar side and becoming merged into the deep fascia of the forearm. Formerly called "grace Dieu" fascia, it serves to protect the brachial artery and median nerve during phlebotomy of median cubital vein. Synonym: aponeurosis musculi bicipitis brachii, bicipital fascia, lacertus fibrosus, semilunar fascia. (05 Mar 2000) |
