Definitions
For this text, hand will be defined as beginning at carpometacarpal joint
In anatomic position, hand is in supination
Radial: Toward radius and synonymous with lateral(ly)
Ulnar: Toward ulna and synonymous with medial(ly)
Mesial: Toward midline of structure
In the hand, for example, 3rd digit is more mesial than 2nd and 4th digits, which are more mesial than 1st and 5th digits
Opposition: Motion bringing thumb toward other digits; critical motion for grasping objects
