| flexor retinaculum of forearm | Thickening of distal antebrachial fascia just proximal to radiocarpal (wrist) joint. Continuous with extensor retinaculum at margins of forearm. This structure is distinct from the transverse carpal ligament, commonly called "the flexor retinaculum," which forms the roof of the carpal tunnel. Synonym: flexor retinaculum of forearm, palmar carpal ligament. (05 Mar 2000) |

| forearm | <anatomy> That part of the arm or fore limb between the elbow and wrist; the antibrachium. Source: Websters Dictionary (01 Mar 1998) |
| forearm fractures | <radiology> Monteggia proximal ulnar fracture dislocated radial head, Galeazzi radial fracture dislocated distal ulna, mnemonic: MUGR (Monteggia ulna, Galeazzi radius), Monteggia More common (12 Dec 1998) |
| forearm injuries | Injuries to the part of the upper limb of the body between the wrist and elbow. (12 Dec 1998) |
| lateral border of forearm | An imaginary line running along the outermost extent of the forearm separating anterior and posterior surfaces laterally. Synonym: margo lateralis antebrachii, margo radialis antebrachii, radial border of forearm. (05 Mar 2000) |
| lateral cutaneous nerve of forearm | <anatomy, nerve> The terminal cutaneous branch of the musculocutaneous nerve that emerges between bicips brachii and brachialis muscles to supply the skin of the radial side of the forearm. Synonym: nervus cutaneus antebrachii lateralis, lateral cutaneous nerve of forearm. (05 Mar 2000) |
| abdominal external oblique muscle | <anatomy, muscle> Origin, fifth to twelfth ribs; insertion, anterior half of lateral lip of iliac crest, inguinal ligament, and anterior layer of the rectus sheath; action, diminishes capacity of abdomen, draws thorax downward; nerve supply, thoracoabdominal nerves. Synonym: musculus obliquus externus abdominis, abdominal external oblique muscle. (05 Mar 2000) |
| abdominal internal oblique muscle | <anatomy, muscle> Origin, iliac fascia deep to lateral part of inguinal ligament, anterior half of crest of ilium, and lumbar fascia; insertion, tenth to twelfth ribs and sheath of rectus; some of the fibres from inguinal ligament terminate in the conjoint tendon; action, diminishes capacity of abdomen, flexes lumbar vertebral column (bends thorax forward); nerve supply, lower thoracic. Synonym: musculus obliquus internus abdominis, abdominal internal oblique muscle. (05 Mar 2000) |
| aponeurosis of external abdominal oblique muscle | <anatomy> Broad, flat tendinous portion of the external abdominal oblique muscle. The fleshy fibres of the muscle end in the aponeurosis along a line descending vertically from the costochondral joint of the ninth rib then turning laterally just below the level of the umbilicus toward the anterior superior iliac spine. The fibres of the aponeurosis run medially and inferiorly, contributing to the anterior wall of the sheath of the rectus abdominis muscle and decussating with those of the contralateral aponeurosis at the median linea alba. Inferomedially, the aponeurosis is attached to the upper border of the pubic symphysis, the pubic crest and pubic tubercle. Between the anterior superior iliac spine and the pubic tubercle, it is thickened and turned under, forming the inguinal ligaments. The portion of the aponeurosis attached to the pubic bone forms the superficial inguinal ring by splitting into medial and lateral crura. See: external spermatic fascia, inguinal ligament, lacunar ligament, pectineal ligament, reflected inguinal ligament, superficial inguinal ring, rectus sheath. (05 Mar 2000) |
| aponeurosis of internal abdominal oblique muscle | <anatomy> Broad, flat tendinous portion of the internal abdominal oblique muscle. The fleshy fibres of the muscle end in the aponeurosis lateral to the semilunar line. The uppermost portion of the aponeurosis is attached to the outer surfaces and lower borders of the seventh to ninth costal cartilages. Of the portion extending between the costoxiphoid margin and the pubis, the upper two-thirds splits into anterior and posterior laminae at the lateral border of the rectus abdominis muscle to contribute to the anterior and posterior walls of the sheath of the rectus abdominis muscle as they extend to the midline linea alba. The lower third of the aponeurosis does not split but joins the aponeuroses of the external abdominal oblique and transversus abdominis muscles to form the anterior wall of the sheath of the rectus abdominis muscle. The fibres of the portion of the aponeurosis contributing to the rectus sheath decussate with those of the contralateral aponeurosis in the linea alba. The lowermost portion of the aponeurosis blends with the aponeurosis of the transversus abdominis muscle to form the conjoint tendon, attaching to the pubic crest and often the pecten pubis, thus forming the posterior wall of the inguinal canal at the superficial inguinal ring. See: cremasteric fascia, conjoint tendon, rectus sheath. (05 Mar 2000) |
| astigmatism of oblique pencils | An aberration occurring when a bundle of light rays strikes a refracting medium in some other direction than parallel to the axis of the lens. (05 Mar 2000) |
| Marshall's oblique vein | A small vein on the posterior wall of the left atrium which merges with the great cardiac vein to form the coronary sinus; it is developed from the left common cardinal vein, and occasionally persists as a left superior vena cava. Synonym: vena obliqua atrii sinistri, Marshall's oblique vein. (05 Mar 2000) |
| sliding oblique osteotomy | An oral surgical procedure in which the mandibular ramus is cut vertically from the sigmoid notch to the angle to facilitate posterior repositioning of the mandible in correction of mandibular prognathism; it may be performed extraorally or intraorally, and is similar to vertical osteotomy. (05 Mar 2000) |
| superior oblique | <anatomy, muscle> Origin, above the medial margin of the optic canal; insertion, by a tendon passing through the trochlea, or pulley, and then reflected backward, downward, and laterally to the sclera between the superior and lateral recti; action, primary, intorsion; secondary, depression and abduction; nerve supply, trochlear nerve. Synonym: musculus obliquus superior. (05 Mar 2000) |
| superior oblique muscle of head | <anatomy, muscle> Origin, transverse process of atlas; insertion, lateral third of inferior nuchal line; action, rotates head; nerve supply, suboccipital. See: suboccipital muscles. Synonym: musculus obliquus capitis superior, superior oblique muscle of head. (05 Mar 2000) |
