Topics of the lesson: Surface landmarks, borders of regions, general descriptions of regions. Scapular region: bone base, layers, supraspinous fossa and infraspinous fossa; fascial-cellular formations and their relationship with neighboring regions; blood supply and innervation. Deltoid region: layers; fascial-cellular formations; vessels, nerves, synovial bags. Subclavian region: layers, fascial-cellular formations, blood supply and innervation. Axillary region: borders; the walls of the axillary fossa; neurovascular formations; lymph nodes and ways of lymph outflow; triangular and quadrilateral foramen; connection of the axillary fossa with the cellular space of neighboring regions. Shoulder joint: articular capsule, its weak points, ligament apparatus; blood supply and innervation of the joint; position of the humeral head at dislocations; arterial collateral regions of the shoulder joint.
