Thumb, Adducted

Definition:

Subjective: In the resting position, the tip of the thumb is on, or near, the palm, close to the base of the fourth or fifth finger

Comments:

The thumb is both flexed and adducted. Lesser degrees of adduction than that specified here may warrant the use of this term, for example, when the tip of the thumb lies near the base of F2 or F3.
