Sulcus bicipitalis lateralis

Arm cross-section

Border dorsally	back group of arm muscles
Border ventrally	Front group of arm muscles
Content	V. cephalica

It is a soft groove on the lateral side of the arm that separates the muscles of the anterior and posterior regio brachialis groups. It is conditioned by drawing the fascia brachii into the depth of the intermuscular septum – septum intermusculare brachii laterale. Together with the sulcus bicipitalis medialis, two septa and the humerus, it defines two osteofacial spaces – regio brachii anterior and regio brachii posterior. The vena cephalica passes through here.
