The lowerend of the incision divides the lower fibres of the anconeus transversely at theirattachment to the posterior border of the ulna, because the muscle extends for aconsiderable distance down the forearm. The incision, therefore, falls accuratelyalong the interval between the muscles supplied by branches of the musculo-spiral. T^T^?k^^ Triceps liF /jj Anconeus m.
