Upper Extremity

uper_extremity1.gif

In human anatomy, the upper limb (also upper extremity) refers to the region distal to the deltoid (Shoulder). In formal usage, the term "arm" only refers to the structures from the shoulder to the elbow, explicitly excluding the forearm, and thus "upper limb" and "arm" are not synonymous. However, in casual usage, the terms are often used interchangeably. The term "upper arm" is redundant in anatomy, but in informal usage is used to distinguish between the two terms.

The upper limb 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.
