| cushion of epiglottis | A convexity at the lower part of the epiglottis over the upper part of the thyroepiglottic ligament. Synonym: tuberculum epiglotticum, cushion of epiglottis. (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 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) |
| 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) |
| cuspad | In a direction toward the cusp of a tooth. Origin: L. Ad, to (05 Mar 2000) |
| cuspal | <dentistry> The chewing or tearing points of the cuspids, bicuspids, and molars. (08 Jan 1998) |
| cuspal interference | A condition of tooth contact's which diverts the mandible from a normal path of closure to centric jaw relation. Synonym: cuspal interference, interceptive occlusal contact, premature contact. (05 Mar 2000) |
| cusped geometry | <radiobiology> This is a description of a magnetic field configuration where the magnetic field lines, rather than closing in on themselves, tend to squirt out and form cusps at certain points. The magnetic field lines are everywhere convex towards the centre. Such a geometry is interesting because it is theoretically stable against a variety of magnetohydrodynamic instabilities. However, confinement is typically poor because of the open field lines at the cusps. (13 Nov 1997) |
| cuspid | The third tooth to the left and to the right of the midline of either jaw, situated between the second incisor and the premolar teeth (bicuspid). (12 Dec 1998) |
| cuspid tooth | <dentistry> A tooth having a crown of thick conical shape and a long, slightly flattened conical root; there are two canine teeth in each jaw, one on either side adjacent to the distal surface of the lateral incisors, in both the deciduous and the permanent dentition. Synonym: dens caninus, canine, cuspid tooth, cuspidate tooth, cuspid, dens angularis, dens cuspidatus, eye tooth. (05 Mar 2000) |
| cuspidate | Tapering into a sharp, rigid point. (09 Oct 1997) |
| cuspis | Synonym: cusp. Origin: L. A point (05 Mar 2000) |
| cuspis anterior valvae atrioventricularis dextrae/sinistrae | The anterior leaflet or valvule of either the tricuspid or mitral valves. Synonym: cuspis anterior valvae atrioventricularis dextrae/sinistrae. (05 Mar 2000) |
