Actions
Opposition of the thumb is a combination of actions that allows the tip of the thumb to touch the tips of other fingers. The part of opposition that this muscle is responsible for is the flexion of the thumb's metacarpal at the first carpometacarpal joint. This specific action cups the palm. Many texts, for simplicity, use the term opposition to represent this component of true opposition. In order to truly oppose the thumb, the actions of a number of other muscles are needed at the thumb's metacarpophalangeal joint.

Famous quotes containing the word actions:

—François, Duc De La Rochefoucauld (1613–1680)
“What is the use of aesthetics if they can neither teach how to produce beauty nor how to appreciate it in good taste? It exists because it behooves rational human beings to provide reasons for their actions and assessments. Even if aesthetics are not the mathematics of beauty, they are the proof of the calculation.”
—Franz Grillparzer (1791–1872)
“Can it be borne, this bodying-forth by wind
Of joy my actions turn on, like a thread
Carrying beads?”
—Philip Larkin (1922–1986)
