| arcus palatini | See: palatoglossal arch, palatopharyngeal arch. (05 Mar 2000) |
|---|---|
| arcus palatoglossus | One of a pair of ridges or folds of mucous membrane passing from the soft palate to the side of the tongue; it encloses the palatoglossus muscle and forms anterior margin of the tonsillar fossa. Also demarcates oral cavity from isthmus of fauces. Synonym: arcus palatoglossus, anterior palatine arch, anterior pillar of fauces, arcus glossopalatinus, glossopalatine arch, glossopalatine fold. (05 Mar 2000) |
| arcus palatopharyngeus | One of a pair of ridges or folds of mucous membrane which passes downward from the posterior margin of the soft palate to the lateral wall of the pharynx. It encloses the palatopharyngeus muscle and forms the posterior margin of the tonsillar fossa. It also demarcates the isthmus of fauces from oropharynx. Synonym: arcus palatopharyngeus, pharyngopalatine arch, posterior palatine arch, posterior pillar of fauces. (05 Mar 2000) |
| arcus palmaris profundus | deep palmar (arterial) arch |
| arcus palmaris superficialis | superficial palmar (arterial) arch |
| arcus pedis longitudinalis | See: medial longitudinal arch of foot, lateral longitudinal arch of foot. Synonym: arcus pedis longitudinalis, lateral part of longitudinal arch of foot. (05 Mar 2000) |
| arcus pedis longitudinalis pars lateralis | Formed by calcaneus, cuboid and two lateral metatarsals; the combined arch is supported normally by ligaments, intrinsic muscles, and the tendons of extrinsic muscles of the foot. Synonym: arcus pedis longitudinalis pars lateralis. (05 Mar 2000) |
| arcus pedis longitudinalis pars medialis | Formed by the calcaneus, talus, navicular, three cuneiform bones, and the three medial metatarsals. Synonym: arcus pedis longitudinalis pars medialis. (05 Mar 2000) |
| arcus pedis transversalis | The arch formed by the proximal parts of the metatarsal bones, the three cuneiform bones, and the cuboid. Synonym: arcus pedis transversalis. (05 Mar 2000) |
| arcus plantaris | The arterial arch formed by the lateral plantar artery running across the bases of the metatarsal bones and anastomosing with the dorsal pedis artery, either of two bony arch's of the foot, longitudinal arch or transverse arch. See: medial longitudinal arch of foot, lateral longitudinal arch of foot, transverse arch of foot. Synonym: arcus plantaris, plantar arterial arch. (05 Mar 2000) |
| arcus posterior atlantis | The posterior arch of the atlas that connects the lateral masses of the atlas posteriorly, forming the posterior wall of the vertebral canal at this level. Synonym: arcus posterior atlantis. (05 Mar 2000) |
| arcus pubis | The arch formed by the symphysis, bodies and inferior rami of the pubic bones. See: subpubic angle. Synonym: arcus pubis. (05 Mar 2000) |
| arcus raninus | An anastomosis between the right and the left end-branch of the deep lingual artery. Synonym: arcus raninus. (05 Mar 2000) |
| arcus senilis | <clinical sign, ophthalmology> An opaque ring around the iris (coloured portion of the eye), seen most often in elderly people. (27 Sep 1997) |
