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) |
| pterygomaxillary | <anatomy> Of or pertaining to the inner pterygoid plate, or pterygoid bone, and the lower jaw. Origin: Pterygoid + maxillary. Source: Websters Dictionary (01 Mar 1998) |
| pterygomaxillary fissure | The narrow gap between the lateral pterygoid plate and the infratemporal surface of the maxilla through which the infratemporal fossa communicates with the pterygopalatine fossa; gives passage to the third part of the maxillary artery and the posterior superior alveolar arteries, veins and nerves. Synonym: fissura pterygomaxillaris, fissura pterygopalatina. (05 Mar 2000) |
| pterygomaxillary fossa | Sphenomaxillary fossa, a small pyramidal space, housing the pterygopalatine ganglion, between the pterygoid process, the maxilla, and the palatine bone. Synonym: fossa pterygopalatina, Bichat's fossa, pterygomaxillary fossa, sphenomaxillary fossa. (05 Mar 2000) |
| pterygium |
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.
