Arm (Brachial Region)

  • Philip Thorek


The arm in the adult appears to be flattened from side to side because of grouping of the anterior and the posterior arm muscles (Fig. 614). The fullness anteriorly is produced by the fleshy belly of the biceps brachii; this is lost under the deltoid muscle. Over the posterior aspect of the arm the fullness is produced by the triceps brachii muscle; this fades into a flattened distal appearance, produced by the triceps tendon.
