vortex

pl. vortexes, vortices
Etymology: L, whirl
a whirlpool effect produced by the whirling of a more or less cylindric mass of fluid (liquid or gas). The velocity of the motion increases as the radius of the circle described by the motion decreases; the velocity decreases as the radius increases. Tornadoes and whirlpools are examples of free vortexes.

ver·ti·cil

(vĕr'ti-sil)
A collection of similar parts radiating from a common axis.
Synonym(s): vortex (1) , whorl (4) .
[L. verticillus, the whirl of a spindle, dim. of vertex, a whirl]

vor·tex len·tis

(vōr'teks len'tis)
One of the stellar figures on the surface of the lens of the eye.
Synonym(s): vortex (3) .

whorl

(wŏrl)
1. A turn of the spiral cochlea of the ear.
2. Synonym(s): vortex of heart.
3. A turn of a concha nasalis.
4. Synonym(s): verticil.
5. An area of hair growing in a radial manner suggesting whirling or twisting.
Synonym(s): vortex (2) .
6. One of the distinguishing patterns in the Galton system of classification of fingerprints.
