The central, large figure is a detailed depiction of the human skeleton, with muscles, blood vessels, and some internal organs illustrated in red and black lines against a white body outline. The figure's skull has a distinctive, large, smiling face. To the lower left, a large, macabre skull detail with wide-open eyes and a grin is shown. To the right, a smaller figure highlights the spine and back anatomy. Tibetan script surrounds the figures, likely labeling specific points or channels relevant to diagnosis and treatment, such as acupuncture points.
