 [tor´shun]
the act of twisting; the state of being twisted. adj., adj tor´sive.
Testicular torsion. From Copstead and Banasik, 2000.

tor·sion

(tōr'shŭn),
1. A twisting or rotation of a part on its long axis or on its mesentery; often associated with compromise of the blood supply.
See also: intorsion, extorsion, dextrotorsion, levotorsion.
2. Twisting of the cut end of an artery to arrest hemorrhage.
See also: intorsion, extorsion, dextrotorsion, levotorsion.
3. Rotation of the eye around its anteroposterior axis.
See also: intorsion, extorsion, dextrotorsion, levotorsion.
[L. torsio, fr. torqueo, to twist]

torsion

Twisting or rotation, especially of a part that hangs loosely on a narrow support. Torsion may affect a loop of bowel or other organ and commonly results in dangerous obstruction to the blood supply of the part. Urgent surgical correction may be needed.

torsion

a phenomenon occurring in embryonic gastropods in which the visceral hump rotates through 180°.

torsion 

Rotation of an eye about an anteroposterior axis. If the upper pole of the vertical meridian of the cornea appears to rotate inward, it is called intorsion, and outward, extorsion. If the eye rotates to the right it may be called dextrotorsion and if it rotates to the left it may be called laevotorsion. It may occur as a result of a head tilt, extraocular muscle weakness or rotation of the eye to a tertiary position. Syn. cycloductin; cyclorotation; torsional movement. See Donder's law; tertiary position; incongruous hemianopia.

1. In dentistry, twisting or rotation of tooth part on its long axis.
2. Twisting cut end of an artery to arrest hemorrhage.
