Chordee :: Chordee (n.) A painful erection of the penis, usually with downward curvature, occurring in gonorrhea..

Spherometer :: Spherometer (n.) An instrument for measuring the curvature of spherical surface, as of lenses for telescope, etc..

Incurvation :: Incurvation (n.) The state of being bent or curved; curvature.

Fair :: Fair (superl.) Without sudden change of direction or curvature; smooth; fowing; -- said of the figure of a vessel, and of surfaces, water lines, and other lines..

Level :: Level (a.) Even; flat; having no part higher than another; having, or conforming to, the curvature which belongs to the undisturbed liquid parts of the earth's surface; as, a level field; level ground; the level surface of a pond or lake..

Osculate :: Osculate (v. t.) To touch closely, so as to have a common curvature at the point of contact. See Osculation, 2..

Umbilicus :: Umbilicus (n.) A point of a surface at which the curvatures of the normal sections are all equal to each other. A sphere may be osculatory to the surface in every direction at an umbilicus. Called also umbilic.

Plane :: Plane (a.) A surface, real or imaginary, in which, if any two points are taken, the straight line which joins them lies wholly in that surface; or a surface, any section of which by a like surface is a straight line; a surface without curvature..

Pseudosphere :: Pseudosphere (n.) The surface of constant negative curvature generated by the revolution of a tractrix. This surface corresponds in non-Euclidian space to the sphere in ordinary space. An important property of the surface is that any figure drawn upon it can be displaced in any way without tearing it or altering in size any of its elements.

Aduncity :: Aduncity (n.) Curvature inwards; hookedness.

Indicatrix :: Indicatrix (n.) A certain conic section supposed to be drawn in the tangent plane to any surface, and used to determine the accidents of curvature of the surface at the point of contact. The curve is similar to the intersection of the surface with a parallel to the tangent plane and indefinitely near it. It is an ellipse when the curvature is synclastic, and an hyperbola when the curvature is anticlastic..

Curvature :: Curvature (n.) The act of curving, or the state of being bent or curved; a curving or bending, normal or abnormal, as of a line or surface from a rectilinear direction; a bend; a curve..

Aplanatic :: Aplanatic (a.) Having two or more parts of different curvatures, so combined as to remove spherical aberration; -- said of a lens..

Scoliosis :: Scoliosis (n.) A lateral curvature of the spine.

Arch :: Arch (n.) Any curvature in the form of an arch; as, the arch of the aorta..

Chicken-breasted :: Chicken-breasted (a.) Having a narrow, projecting chest, caused by forward curvature of the vertebral column..

Arc :: Arc (n.) A curvature in the shape of a circular arc or an arch; as, the colored arc (the rainbow); the arc of Hadley's quadrant..

Ophthalmometer :: Ophthalmometer (n.) An instrument devised by Helmholtz for measuring the size of a reflected image on the convex surface of the cornea and lens of the eye, by which their curvature can be ascertained..

Pott''s Disease :: Pott's disease () Caries of the vertebrae, frequently resulting in curvature of the spine and paralysis of the lower extremities; -- so named from Percival Pott, an English surgeon..

Anticlastic :: Anticlastic (a.) Having to opposite curvatures, that is, curved longitudinally in one direction and transversely in the opposite direction, as the surface of a saddle..
