This anatomical illustration displays a complete adult human skeleton in a relaxed, slightly asymmetrical stance, emphasizing structural relationships between major bone groups. Blue shading specifically marks the rib cage (including costal cartilages), sacrum, and pelvic girdle to aid identification of key supportive and protective structures. The clean line art and neutral background make it suitable for educational or clinical use.
