Movements
The articulation of the hand and wrist considered as a whole involves four articular surfaces:
- (a) the inferior surfaces of the radius and articular disk;
- (b) the superior surfaces of the navicular, lunate, and triangular, the pisiform having no essential part in the movement of the hand;
- (c) the S-shaped surface formed by the inferior surfaces of the navicular, lunate, and triangular;
- (d) the reciprocal surface formed by the upper surfaces of the bones of the second row.
These four surfaces form two joints: (1) a proximal, the wrist-joint proper; and (2) a distal, the mid-carpal joint.

Famous quotes containing the word movements:
“All great movements are popular movements. They are the volcanic eruptions of human passions and emotions, stirred into activity by the ruthless Goddess of Distress or by the torch of the spoken word cast into the midst of the people.”
—Adolf Hitler (1889–1945)
“Virtues are not emotions. Emotions are movements of appetite, virtues dispositions of appetite towards movement. Moreover emotions can be good or bad, reasonable or unreasonable; whereas virtues dispose us only to good. Emotions arise in the appetite and are brought into conformity with reason; virtues are effects of reason achieving themselves in reasonable movements of the appetites. Balanced emotions are virtue’s effect, not its substance.”
—Thomas Aquinas (c. 1225–1274)
“Who among us has not, in moments of ambition, dreamt of the miracle of a form of poetic prose, musical but without rhythm and rhyme, both supple and staccato enough to adapt itself to the lyrical movements of our souls, the undulating movements of our reveries, and the convulsive movements of our consciences? This obsessive ideal springs above all from frequent contact with enormous cities, from the junction of their innumerable connections.”
—Charles Baudelaire (1821–1867)
