| cusp height | The shortest distance between the tip of a cusp and its base plane, the shortest distance between the deepest part of the central fossa of a posterior tooth and a line connecting the points of the cusps of the tooth. Facial height, the linear dimension in the midline from the hairline to the menton. Nasal height, the distance between the nasion and the lower border of the nasal aperture. Orbital height, the distance between the midpoints of the upper and lower margins of the orbit. (05 Mar 2000) |

| height | Vertical measurement. Anterior facial height (AFH), in cephalometrics, the linear measurement from the nasion to the menton. Height of contour, the line encircling a tooth or other structure at its greatest bulge or diameter with respect to a selected path of insertion. (05 Mar 2000) |

| height of contour | See: height of contour. (05 Mar 2000) |
| height vertigo | Dizziness experienced when looking down from a great height or in looking up at a high building or cliff. Synonym: vertical vertigo. (05 Mar 2000) |
| pulse height analyzer | Electronic circuitry that determines the energy of scintillations recorded by a detector, allowing use of a discriminator to select for photons of a specific type. (05 Mar 2000) |
| diameter at breast height | The width of a plant stem (for example, tree trunk) as measured at 4.5 feet above the ground surface. (09 Oct 1997) |
| length-height index | The relation of the height to the length of the skull: (height × 100)/length. Synonym: height-length index, length-height index, transversovertical index. (05 Mar 2000) |
| anterior cusp of atrioventricular valve | The anterior leaflet or valvule of either the tricuspid or mitral valves. Synonym: cuspis anterior valvae atrioventricularis dextrae/sinistrae. (05 Mar 2000) |
| apex of cusp of tooth | The tip of the peaklike projections from the crown of a tooth. Synonym: apex cuspidis dentis. (05 Mar 2000) |
| posterior cusp of atrioventricular valve | The posterior leaflet of either the tricuspid or mitral valves. Synonym: cuspis posterior valvae atrioventricularis dextrae/sinistrae. (05 Mar 2000) |
| cusp | A rigid, sharp point, especially on a leaf. (09 Oct 1997) |
| cusp angle | The angle made by the slopes of a cusp with the plane which passes through the tip of the cusp and which is perpendicular to a line bisecting the cusp, measured mesiodistally or buccolingually, the angle made by the slopes of a cusp with a perpendicular line bisecting the cusp, measured mesiodistally or buccolingually, one-half of the included angle between the buccal and lingual or mesial and distal cusp inclines. (05 Mar 2000) |
| cusp of Carabelli | A fifth cusp found on the maxillary first molars, usually located lingual to the mesiolingual cusp. (05 Mar 2000) |
| cusp of tooth | An elevation or mound on the crown of a tooth making up a part of the occlusal surface. Synonym: cuspis dentis, cuspis coronae. (05 Mar 2000) |
| semilunar cusp | One of the three semilunar segments serving as the three cusps of a valve preventing regurgitation at the beginning of the aorta; a similar valve guards the entrance of the pulmonary trunk; the segments are named, respectively, anterior, right, and left in the pulmonary valve, and posterior, right, and left in the aortic valve.
