description

The spinal column consists of vertebral bodies which together form 7 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 4 coccygeal vertebrae (see Transparency 1). A typical vertebra consists of two basic parts: the ventral vertebral body and the dorsal vertebral arch. Between the vertebral bodies are the intervertebral disks, which give the spinal column its flexibility. Together, the vertebral bodies and the intervertebral disks form a strong column supporting the head and trunk, while the vertebral arch protects the spinal cord. When the spinal column is viewed from the side, four flexures are visible: the thoracic and the sacrococcygeal flexures are concave ventrally, while the cervical and lumbar flexures are convex ventrally.In a supine position, L 3 is the highest point and L 5 the lowest point of the lumbar flexure.
