| ethmoidal crest | Bony ridge which articulates with, or provides attachment for, any part of the ethmoid bone, especially the middle nasal concha. See: ethmoidal crest of maxilla, ethmoidal crest of palatine bone. Synonym: crista ethmoidalis. (05 Mar 2000) |
|---|---|
| ethmoidal crest of maxilla | A ridge on the upper part of the nasal surface of the frontal process of the maxilla that gives attachment to the anterior portion of the middle nasal concha. Synonym: crista ethmoidalis maxillae. (05 Mar 2000) |
| ethmoidal crest of palatine bone | A ridge on the medial surface of the perpendicular part of the palatine bone to which the middle nasal concha attaches posteriorly. Synonym: crista ethmoidalis ossis palatini. (05 Mar 2000) |
| ethmoidal foramen | Either of two foramina formed by grooves on either edge of the ethmoidal notch of the frontal bone, and completed by similar grooves on the ethmoid bone: anterior ethmoidal foramen, located in an anterior position; posterior ethmoidal foramen located in a posterior position. Synonym: foramen ethmoidale. (05 Mar 2000) |
| ethmoidal groove | A groove on the inner surface of each nasal bone, lodging the external nasal branch of the anterior ethmoid nerve. Synonym: sulcus ethmoidalis. (05 Mar 2000) |
| ethmoidal infundibulum | A passage from the middle meatus of the nose communicating with the anterior ethmoidal cells and frontal sinus. Synonym: infundibulum ethmoidale, ethmoid infundibulum. (05 Mar 2000) |
| ethmoidal labyrinth | A mass of air cells with thin bony walls forming part of the lateral wall of the nasal cavity; the cells are arranged in three groups, anterior, middle, and posterior, and are closed laterally by the orbital plate which forms part of the wall of the orbit. Synonym: labyrinthus ethmoidalis, ectethmoid, ectoethmoid, lateral mass of ethmoid bone. (05 Mar 2000) |
| ethmoidal-lacrimal fistula | A fistulous communication between the lacrimal sac and the ethmoidal sinus. Synonym: internal lacrimal fistula. (05 Mar 2000) |
| ethmoidal notch | An oblong gap between the orbital parts of the frontal bone in which the ethmoid bone is lodged. Synonym: incisura ethmoidalis. (05 Mar 2000) |
| ethmoidal process | A projection of the inferior concha, situated behind the lacrimal process and articulating with the uncinate process of the ethmoid. Synonym: processus ethmoidalis. (05 Mar 2000) |
| ethmoidal veins | Veins that accompany the anterior and posterior ethmoidal arteries and pass into the superior ophthalmic vein; they drain the ethmoidal sinuses. Synonym: venae ethmoidales. (05 Mar 2000) |
| lateral nasal branches of anterior ethmoidal nerve | <anatomy, nerve> Branches of nasociliary nerve distributed to walls of nasal cavity. Synonym: rami nasales laterales nervi ethmoidalis anterioris. (05 Mar 2000) |
| superior branch of the superior gluteal artery | <anatomy, artery> Runs between gluteus medius and minimus muscles, supplying both, and continuing to reach tensor fascia lata muscle. Synonym: ramus superior arteriae gluteae superioris. (05 Mar 2000) |
| superior dental branches of superior dental plexus | Branches passing from the superior dental plexus to the roots of the teeth of the upper jaw. Synonym: rami dentales superiores plexus dentalis superioris. (05 Mar 2000) |
| superior gingival branches of superior dental plexus | Branches of superior dental plexus to gingiva of upper jaw. Synonym: rami gingivales superiores plexus dentalis superioris. (05 Mar 2000) |
