• Anatomy. —The triceps brachii is the principal structure which fills the space between the posterior border of the scapula and the humerus. 
• However, radial paralysis is encountered following injury to the nerve occasioned by its being stretched, as in cases where the triceps brachii is unduly extended in restraining subjects by means of a casting harness. 
• The radial nerve supplies branches to the three heads of the triceps brachii, to the common and lateral extensors of the digit and also to the skin covering the forearm. 
• The triceps brachii is the chief antagonist of the biceps brachii. 
• Thus it is seen, the biceps brachii is a weight bearing structure, as well as one that has to do with swinging the leg.
