| pterygoid muscles | Two of the masticatory muscles: the internal, or medial, pterygoid muscle and external, or lateral, pterygoid muscle. Action of the former is closing the jaws and that of the latter is opening the jaws, protruding the mandible, and moving the mandible from side to side. (12 Dec 1998) |
|---|---|
| pterygoid nerve | <anatomy, nerve> One of two motor branches, lateral and medial, of the mandibular nerve, supplying the lateral and medial pterygoid muscles with fibres of the motor root of the trigeninal nerve. Synonym: nervus pterygoideus. (05 Mar 2000) |
| pterygoid notch | The cleft between the medial and lateral laminae of the pterygoid process of the sphenoid bone into which the pyramidal process of the palatine bone is fitted. Synonym: incisura pterygoidea, fissura pterygoidea, pterygoid notch. (05 Mar 2000) |
| pterygoid pit | A depression on the antero-medial side of the neck of the condylar process of the mandible, giving attachment to the lateral pterygoid muscle. Synonym: fovea pterygoidea, pterygoid depression, pterygoid pit. (05 Mar 2000) |
| pterygoid plates | See: lateral pterygoid plate, medial pterygoid plate. (05 Mar 2000) |
| pterygoid plexus | A venous plexus occupying the infratemporal fossa receiving veins accompanying the branches of the maxillary artery, and terminating posteriorly in the maxillary vein; anteriorly the pterygoid plexus drains via the deep facial vein into the facial vein. Synonym: plexus pterygoideus. (05 Mar 2000) |
| pterygoid process | A long process extending downward from the junction of the body and great wing of the sphenoid bone on either side; it is formed of two plates (lateral and medial), united anteriorly but separated below to form the pterygoid notch; the pterygoid fossa is formed by the divergence of these two plates posteriorly. Synonym: processus pterygoideus, os pterygoideum. (05 Mar 2000) |
| pterygoid ridge of sphenoid bone | A rough ridge marking the angle of union of the temporal and infratemporal surfaces of the greater wing of the sphenoid bone. Synonym: crista infratemporalis, pterygoid ridge of sphenoid bone. (05 Mar 2000) |
| pterygoid tubercle | A slight prominence on the posterior surface of the medial pterygoid plate, inferior and to the medial side of the pterygoid canal. (05 Mar 2000) |
| pterygoid tuberosity | A roughened area on the internal aspect of the mandible, giving attachment to fibres of the medial pterygoid muscle. Synonym: tuberositas pterygoidea. (05 Mar 2000) |
| pterygomandibular | Relating to the pterygoid process and the mandible. (05 Mar 2000) |
| pterygomandibular ligament | A tendinous thickening of the buccopharyngeal fascia, separating and giving origin to the buccinator muscle anteriorly and the superior constrictor of the pharynx posteriorly. Synonym: raphe pterygomandibularis, pterygomandibular ligament. (05 Mar 2000) |
| pterygomandibular raphe | A tendinous thickening of the buccopharyngeal fascia, separating and giving origin to the buccinator muscle anteriorly and the superior constrictor of the pharynx posteriorly. Synonym: raphe pterygomandibularis, pterygomandibular ligament. (05 Mar 2000) |
| pterygomandibular space | The area between the mandibular ramus and the pterygoid process of the sphenoid bone. (05 Mar 2000) |
| pterygomaxillare | The point where the pterygoid process of the sphenoid bone and the pterygoid process of the maxilla begin to form the pterygomaxillary fissure; the lowest point of the opening is used in cephalometrics. (05 Mar 2000) |
| pterygoid notch |
This notch is located at the pyramidal process of the palatine bone between the pterygoid processes and the maxillary tuberosity. This has been considered a landmark for the distal limit of the maxillary subperiosteal implant.

pl. ptery´gia [Gr. pterygion wing] a winglike structure, applied especially to an abnormal triangular fold of membrane, in the interpalpebral fissure, extending from the conjunctiva to the cornea, being immovably united to the cornea at its apex, firmly attached to the sclera throughout its middle portion, and merged with the conjunctiva at its base.
