Compare and contrast the femoral and obturator nerve composition and distribution.
The vertebral column, also called the backbone or spine, is a part of the axial skeleton system. This column houses the spinal canal or cavity which contains the spinal cord. Hence, the vertebral column along with the spinal cavity is responsible for protection of the spinal cord. The vertebral column consists of a segmented series of bones called vertebrae, each of which is separated by intervertebral discs. In totality, there are thirty three vertebrae that make up the vertebral column. Depending on these vertebrae, the vertebral column is divided into five divisions:
- Cervical spine: which consists of seven cervical vertebrae, and represented as C1–C7.
- Thoracic spine: which consists of twelve thoracic vertebrae, and represented as T1–T12.
- Lumbar spine: which consists of five lumbar vertebrae, and represented as L1–L5.
- Sacrum: which consists of five sacrum vertebrae (S1–S5) which are fused together.
- Coccyx: which consists of four fused vertebrae.
The nerves of the nervous system which connect to the spinal cord through the vertebral column are called spinal nerves. Similar to the anatomy of the spine, the spinal nerves can be grouped as Cervical nerves, Thoracic nerves, Lumbar nerves, Sacral nerves, and coccygeal nerves.
