Label Id Description
Oculomotor Nuclear Complex D065838 [A collection of nuclei in the midbrain tegmentum for the OCULOMOTOR NERVE fibers. ]
Odds Ratio D016017 [The ratio of two odds. The exposure-odds ratio for case control data is the ratio of the odds in favor of exposure among cases to the odds in favor of exposure among noncases. The disease-odds ratio for a cohort or cross section is the ratio of the odds in favor of disease among the exposed to the odds in favor of disease among the unexposed. The prevalence-odds ratio refers to an odds ratio derived cross-sectionally from studies of prevalent cases. ]
Odonata D063191 [A small suborder of Odonata that has members with intermediate morphology between Anisoptera and Zygoptera suborders. , An order of insects comprising three suborders: Anisoptera, Zygoptera, and Anisozygoptera. They consist of dragonflies and damselflies. ]
Odontoblasts D009804 [The mesenchymal cells which line the DENTAL PULP CAVITY and produce DENTIN. They have a columnar morphology in the coronal pulp but are cuboidal in the root pulp, or when adjacent to tertiary dentin. ]
Odontodysplasia D018126 [A localized arrested tooth development which appears to involve most commonly the anterior teeth, usually on one side of the midline, most often the maxillary central and lateral incisors. Roentgenographically, the teeth have a ghostlike appearance. Calcification and bits of prismatic enamel may be found in the pulp and the enamel is thin and absent in part. (Jablonski, Illustrated Dictionary of Dentistry, 1982) ]
Odontogenesis D009805 [The process of TOOTH formation. It is divided into several stages including: the dental lamina stage, the bud stage, the cap stage, and the bell stage. Odontogenesis includes the production of tooth enamel (AMELOGENESIS), dentin (DENTINOGENESIS), and dental cementum (CEMENTOGENESIS). ]
Odontogenic Cyst, Calcifying D018333 [A mixed radiolucent-radiopaque lesion of the jaws with features of both a cyst and a solid neoplasm. It is characterized microscopically by an epithelial lining showing a palisaded layer of columnar basal cells, presence of ghost cell keratinization, dentinoid, and calcification. (Stedman, 25th ed) ]
Odontogenic Cysts D009807 [Cysts found in the jaws and arising from epithelium involved in tooth formation. They include follicular cysts (e.g., primordial cyst, dentigerous cyst, multilocular cyst), lateral periodontal cysts, and radicular cysts. They may become keratinized (odontogenic keratocysts). Follicular cysts may give rise to ameloblastomas and, in rare cases, undergo malignant transformation. ]
Odontogenic Tumor, Squamous D051527 [A well-differentiated, benign, hamartomatous proliferation of odontogenic epithelium, probably arising from the rests of Malassez. ]
Odontogenic Tumors D009808 [Neoplasms produced from tooth-forming tissues. ]
Odontoid Process D009809 [The toothlike process on the upper surface of the axis, which articulates with the CERVICAL ATLAS above. ]
Odontoma D009810 [A mixed tumor of odontogenic origin, in which both the epithelial and mesenchymal cells exhibit complete differentiation, resulting in the formation of tooth structures. (Jablonski, Illustrated Dictionary of Dentistry, 1982) ]
Odontometry D009811 [Measurement of tooth characteristics. ]
Odorants D009812 [The volatile portions of chemical substances perceptible by the sense of smell. ]
Oedipus Complex D009813 [Attachment of the child to the parent of the opposite sex, accompanied by envious and aggressive feelings toward the parent of the same sex. ]
Oenanthe D031050 [A plant genus of the family APIACEAE that is sometimes called Hemlock Water Dropwort but should not be confused with HEMLOCK. It contains enanthotoxin. ]
Oenococcus D056585 [A genus of GRAM-POSITIVE COCCI in the family LEUCONOSTOCACEAE. It is the primary bacteria involved in carrying out malolactic conversion in winemaking. ]
Oenothera D031664 [A plant genus of the family ONAGRACEAE. Members contain oenotheins. ]
Oenothera biennis D031665 [A plant species, of the genus OENOTHERA, family ONAGRACEAE, that is the source of evening primrose oil. ]
Oesophagostomiasis D009814 [Infection of the intestinal tract with worms of the genus OESOPHAGOSTOMUM. This condition occurs mainly in animals other than man. ]
