| greater tympanic spine | The anterior edge of the tympanic notch (of Rivinus). Synonym: spina tympanica major. (05 Mar 2000) |

| greater vestibular gland | One of two mucoid-secreting tubuloalveolar glands on either side of the lower part of the vagina, the equivalent of the bulbourethral glands in the male; ensheathed with vestibular bulbs by ischiocavernosus muscles. Thus erection and muscle contraction cause secretion into vestibule of vagina. Synonym: glandula vestibularis major, Bartholin's gland, Duverney's gland, Tiedemann's gland, vulvovaginal gland.

| greater wing of sphenoid bone | Strong squamous processes extending in a broad superolateral curve from the body of the sphenoid bone. The greater wing presents these suraces (facies): 1) cerebral surface: forms anterior third of the floor of the lateral portions of the middle cranial fossa; 2) temporal surface: forms the deepest portion of the temporal fossa; 3) infratemporal surface, forms the "roof" of the infratemporal fossa; 4) orbital surface: forms posterolateral wall of orbit. The greater wing forms the inferior border of the supraorbital fissure, and is perforated at its root by foramina rotundum ovale, and spinosum and the pterygoid canal. Synonym: ala major ossis sphenoidalis, ala temporalis. (05 Mar 2000) |
| groove of greater petrosal nerve | <anatomy, nerve> The groove on the anterior surface of the petrous part of the temporal bone that lodges the greater petrosal nerve. Synonym: sulcus nervi petrosi majoris. (05 Mar 2000) |
| crest of greater tubercle | The ridge below the greater tubercle of the humerus into which the pectoralis major muscle inserts. Synonym: crista tuberculi majoris, bicipital ridges, pectoral ridge. (05 Mar 2000) |
| posterior inferior nasal branches of greater palatine nerve | <anatomy, nerve> Branches of greater palatine nerve to posterior inferior lateral wall of nasal cavity, including posterior aspect of mucosa over posterior portion of inferior nasal concha and meatus; may arise independently from pterygopalatine ganglion. Synonym: rami nasales posteriores inferiores nervi palatini majoris. (05 Mar 2000) |
| hiatus of canal for greater petrosal nerve | The opening on the anterior aspect of the petrous part of the temporal bone which leads to the facial canal and gives passage to the greater petrosal nerve. Synonym: hiatus canalis nervi petrosi majoris, fallopian hiatus, Ferrein's foramen, hiatus canalis facialis, hiatus of canal for greater petrosal nerve. (05 Mar 2000) |
| sulcus for greater palatine nerve | A groove on both the body of the maxilla and the perpendicular plate of the palatine bone; when the bones are articulated the grooves form the greater palatine canal. Synonym: sulcus palatinus major, pterygopalatine groove, sulcus for greater palatine nerve, sulcus pterygopalatinus. (05 Mar 2000) |
| zygomatic border of greater wing of sphenoid bone | The border of the greater wing of the sphenoid that articulates with the zygomatic bone. Synonym: margo zygomaticus alae majoris, zygomatic margin of greater wing of sphenoid bone. (05 Mar 2000) |
| zygomatic margin of greater wing of sphenoid bone | The border of the greater wing of the sphenoid that articulates with the zygomatic bone. Synonym: margo zygomaticus alae majoris, zygomatic margin of greater wing of sphenoid bone. (05 Mar 2000) |
| lateral crus of the greater alar cartilage of the nose | Portion of cartilage extending laterally and posteriorly in a wing-like fashion, supporting the wing of the nose and keeping the nostril patent. Synonym: crus laterale cartilaginis alaris majoris. (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) |
| abdominal muscle deficiency syndrome | <syndrome> Congenital absence (partial or complete) of abdominal muscles, in which the outline of the intestines is visible through the protruding abdominal wall; in males, genitourinary anomalies (urinary tract dilation and cryptorchidism) are also found; genetics unclear. (05 Mar 2000) |
| abductor digiti minimi muscle of foot | Origin, lateral and medial processes of calcanean tuberosity; insertion, lateral side of proximal phalanx of fifth toe; action, abducts and flexes little toe; nerve supply, lateral plantar nerve. Synonym: musculus abductor digiti minimi pedis, abductor muscle of little toe, musculus abductor digiti quinti. (05 Mar 2000) |
