The backbone or spine of the human skeleton that is made up of 26 bones called vertebrae; divided into five sections.
The series of bones and discs linked together to form a flexible column running from the base of the skull to the pelvis.
Firm, flexible, bony column that is the longitudinal axis and chief supporting structure of the human body, extending from the base of the skull to the coccyx. It consists of 26 separate bony parts: 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, a sacrum (composed of 5 fused sacral vertebrae), and a coccyx (composed of 4 fused coccygeal vertebrae). Intervertebral discs separate the vertebrae, which serve for the attachment of muscles. The vertebral column normally has several curves, most visible from a lateral view: a cervical curve, convex ventrally; a thoracic curves, concave ventrally; a lumbar curve, convex ventrally; and a pelvic curve, concave ventrally. Also called rachis; spinal column; spine.
Collective name for the cervical, thoracic, lumbar and sacral bones of the dorsal spine.
The portion of the axial skeleton consisting of vertebrae (7 cervical, 12 thoracic, 5 lumbar, the sacrum, and the coccyx) joined together by intervertebral disks and fibrous tissue. It forms the main supporting axis of the body, encloses and protects the spinal cord, and attaches the appendicular skeleton and muscles for moving the various body parts.
The vertebral column, also known as the spinal column or spine, comprises a series of interconnected vertebrae held together by ligaments. It serves as a supportive axis for the body and safeguards the spinal cord. The vertebral column is composed of seven cervical vertebrae located in the neck, followed by twelve thoracic vertebrae that articulate with the ribs, five lumbar vertebrae situated in the lower back, the sacrum, and the coccyx.
