A triangular bone at the base of the vertebral column formed by fused sacral vertebrae, transmitting axial weight to the pelvic girdle.
Transmits axial body weight from the lumbar spine into the pelvic girdle and encloses the sacral spinal nerves.
Posterior pelvic wall at the base of the vertebral column, wedged between the right and left hip bones.
Jump directly to connected anatomical structures to compare their locations, functions, and 3D relationships.
Skeletal muscles attach across bones and joints; when muscles contract, they pull on bony landmarks to produce movement and maintain posture.
Cartilage, ligaments, and joint capsules connect bones to one another, stabilize joints, and distribute mechanical loads across the skeleton.
The cranial vault and vertebral column form a protective bony enclosure around the brain and spinal cord.
