The first cervical vertebra (C1), supporting the base of the skull and permitting flexion and extension at the craniocervical junction.
Supports the weight of the skull and permits nodding (flexion/extension) movements at the atlanto-occipital joint.
Superior cervical spine (C1 vertebra) at the craniocervical junction beneath the occipital bone.
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.
