Overview
Regions of the upper limb The upper limb is divided into 4 main parts – shoulder, arm, forearm and hand. The shoulder contains two important regions: the deltoid region and the axillary (armpit) region. The arm and forearm contain two regions each that correspond to their anterior and posterior surfaces. Found between the arm and forearm are the anterior and posterior cubital regions. Below the forearm is the carpal region, which connects the forearm with the hand. Lastly, the hand consists of the palm anteriorly, and dorsum of hand posteriorly. The hand can be subdivided into the metacarpal region and the digits. The digits are numbered 1-5 from from the thumb to the little finger.
