Abstract:
The spinal column is separated into the 7 cervical vertebra, the 12 thoracic vertebra, the 5 lumbar vertebra, the 5 sacral vertebra and the 4 coccygeal vertebra. The cervical, thoracic and lumbar vertebra are named as the movable vertebra and the sacral and coccygeal vertebra are named as the fixed vertebra. The lumbar spine includes five large vertebra situated between the rela-tively immobile rib cage and the pelvis. A typical lumbar vertebra has 2 main structures which are vertebral body and vertebral arch. The vertebral body is the anterior portion of a vertebra and the vertebral arch is the posterior portion of it and surrounds the vertebral foramen. In contrast to thoracic vertebra, lumbar vertebra has a wide disc space, sagittally oriented facets, and suf-ficient space between its lamina to permit a considerable range of motion. This report will explains some important normal anatomic features of the lumbar spine and sacrum including with their musclatures and neurovascular structures.
