| superior constrictor muscle of pharynx | Origin, medial pterygoid plate (pterygopharyngeal part), pterygomandibular raphe (buccopharyngeal part), mylohyoid line of mandible (mylopharyngeal part), and the mucous membrane of the floor of the mouth and the side of the tongue (glossopharyngeal part); insertion, pharyngeal raphe in the posterior wall of the pharynx; action, narrows pharynx; nerve supply, pharyngeal plexus. Synonym: musculus constrictor pharyngis superior, musculus cephalopharyngeus. (05 Mar 2000) |
| superior longitudinal muscle of tongue | An intrinsic muscle of the tongue, running from base to tip on the dorsum just beneath the mucous membrane; action, shortens the upper part of the tongue; nerve supply, motor by hypoglossal, sensory by lingual. Synonym: musculus longitudinalis superior, superficial lingual muscle. (05 Mar 2000) |
| superior posterior serratus muscle | <anatomy> Origin, from spinous processes of two lower cervical and two upper thoracic vertebrae; insertion, into lateral side of angles of second to fifth ribs; nerve supply, first to fourth intercostals. Synonym: musculus serratus posterior superior, superior posterior serratus muscle. (05 Mar 2000) |
| superior tarsal muscle | <anatomy> A well defined layer of smooth muscle that extends from the aponeurosis of the musculus levator palpebrae superioris to the superior tarsus; it is innervated by sympathetic nerves and acts to hold the upper lid in an elevated position; its paralysis in Horner's syndrome result in ptosis. Synonym: musculus tarsalis superior, Muller's muscle. (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) |
| illumination, oblique | <microscopy> Illumination from light inclined at an oblique angle to the optical axis. (05 Aug 1998) |
| inferior oblique | <anatomy, muscle> Origin, orbital plate of maxilla lateral to the lacrimal groove; insertion, sclera between the superior and lateral recti; action, primary, extorsion; secondary, elevation and abduction; nerve supply, oculomotor (inferior branch). Synonym: musculus obliquus inferior. (05 Mar 2000) |
| internal oblique | <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) |
| internal oblique line | A ridge on the inner surface of the mandible running from a point inferior to the mental spine upward and backward to the ramus behind the last molar tooth; it gives attachment to the mylohyoid muscle and the lowermost part of the superior constrictor of the pharynx. Synonym: linea mylohyoidea, internal oblique line, mylohyoid ridge. (05 Mar 2000) |
| oblique | 1. Not erect or perpendicular; neither parallel to, nor at right angles from, the base; slanting; inclined. "It has a direction oblique to that of the former motion." (Cheyne) 2.

| oblique arytenoid | <anatomy, muscle> Origin, muscular process of arytenoid cartilage; insertion, summit of arytenoid cartilage of opposite side and continuing as the aryepiglottic muscle in the aryepiglottic fold to the epiglottis; action, narrows the interarytenoid portion of the rima glottidis; nerve supply, recurrent laryngeal. Synonym: musculus arytenoideus obliquus, arytenoideus. (05 Mar 2000) |
