| incisive bone | The anterior and inner portion of the maxilla, which in the foetus and sometimes in the adult is a separate bone; the incisive suture runs from the incisive canal between the lateral incisor and the canine tooth; according to K. Albrecht, the os incisivum is further divided by a suture between the two incisor teeth on each side into two bones, the endognathion and the mesognathion. Synonym: incisive bone, intermaxilla, intermaxillary bone, os intermaxillare, os premaxillare, premaxilla, premaxillary bone. (05 Mar 2000) |
| incisive canal cyst | A cyst in or near the incisive canal, arising from proliferation of epithelial remnants of the nasopalatine duct; the most common maxillary development cyst. Synonym: median anterior maxillary cyst, nasopalatine duct cyst. (05 Mar 2000) |
| incisive duct | A rudimentary duct, or protrusion of the mucous membrane into the incisive canal, on either side of the anterior extremity of the nasal crest. Synonym: ductus incisivus. (05 Mar 2000) |
| incisive foramen | One of several (usually four) openings of the incisive canals into the incisive fossa. Synonym: foramen incisivum, incisor foramen, Stensen's foramen. (05 Mar 2000) |
| incisive fossa | The depression in the midline of the bony palate behind the central incisors into which the incisive canals open. Synonym: fossa incisiva. (05 Mar 2000) |
| incisive papilla | A slight elevation of the mucosa at the anterior extremity of the raphe of the palate. Synonym: papilla incisiva, palatine papilla. Interdental papilla, the gingiva that fills the interproximal space between two adjacent teeth. Synonym: gingival septum, interproximal papilla. (05 Mar 2000) |
| incisive suture | Line of union of the two portions of the maxilla (pre-and postmaxilla); it is present at birth but may persist into old age. Synonym: sutura incisiva, premaxillary suture. (05 Mar 2000) |
| alveolar canals | Canals in the body of the maxilla that transmit nerves and vessels from the alveolar foramina to the maxillary teeth. Synonym: canales alveolares, alveolodental canals, dental canals. (05 Mar 2000) |
| alveolodental canals | Canals in the body of the maxilla that transmit nerves and vessels from the alveolar foramina to the maxillary teeth. Synonym: canales alveolares, alveolodental canals, dental canals. (05 Mar 2000) |
| ampulla of the saemicircular canals | A circumscribed dilation of one extremity of each of the three bony saemicircular canals, anterior, posterior, and lateral; each contains an ampulla of the saemicircular ducts. Synonym: ampulla ossea, osseous ampulla. (05 Mar 2000) |
| anterior saemicircular canals | The three bony tubes in the labyrinth of the ear within which the membranous saemicircular ducts are located; they lie in planes at right angles to each other and are known as anterior saemicircular canal, posterior saemicircular canal, and lateral saemicircular canal. Synonym: canales saemicirculares ossei. (05 Mar 2000) |
| bony saemicircular canals | The three bony tubes in the labyrinth of the ear within which the membranous saemicircular ducts are located; they lie in planes at right angles to each other and are known as anterior saemicircular canal, posterior saemicircular canal, and lateral saemicircular canal. Synonym: canales saemicirculares ossei. (05 Mar 2000) |
| Breschet's canals | Channels in the diploe that accommodate the diploic veins. Synonym: canales diploici, Breschet's canals. (05 Mar 2000) |
| canals for lesser palatine nerves | Canalis's located in the posterior part of the palatine bone. Synonym: canales palatini minores. (05 Mar 2000) |
