My medium or visual is an acrylic painting of the hip joint, a synovial joint. I choose the hip rather than the knee because of the ball and socket type joint. The head of the femur articulates with the cup-shaped acetabulum. The joint cavity is enclosed by a fibrous capsule lined with a connective. It produces a fluid called synovial fluid that lubricates the cartilage covered opposing the bone’s surface. The fibrous capsule comprises internal circular fibers and external longitudinal fibers, strengthened by ligaments and muscles protected.
