text: In human anatomy, the<unk>  (also<unk>  extremity) refers to what in common English is known as the arm, that is, the region of the shoulder to the fingertips.  It includes the entire<unk> , and thus, is not synonymous with the term<unk>  arm.
  The<unk>  includes the following structures:
  Shoulder
  Arm (proper) - in anatomy, the region between the shoulder and the elbow
  Elbow
  Forearm
  Wrist
  Hand
  Note that anatomists use the term arm to denote only the region between the shoulder and the elbow.  This is in contrast to the proper English definition.  Anatomists also use the term leg to refer to the region between the knee and the ankle.  This, however, is the proper and traditional usage of the word, even though popular modern usage tends to include the thigh and foot in the definition.
  The following bones are considered to be part of the<unk> :
  Clavicle - the only bone that directly articulates with the trunk
  Scapula
  Humerus
  Radius<unk> na
  Carpal bones
  Metacarpals
  Phalanges
