Medical Definition of Epicycloid
1.
A curve traced by a point in the circumference of a circle which rolls on the convex side of a fixed circle.
Any point rigidly connected with the rolling circle, but not in its circumference, traces a curve called an epitrochoid. The curve traced by a point in the circumference of the rolling circle when it rolls on the concave side of a fixed circle is called a hypocycloid; the curve traced by a point rigidly connected with the rolling circle in this case, but not its circumference, is called a hypotrochoid. All the curves mentioned above belong to the class class called roulettes or trochoids. See Trochoid.
Origin: Epicycle: cf. F. Epicycloide.
