The spinal cord is divided into four main regions: cervical, thoracic, lumbar, and sacral. Each region contains a specific number of spinal nerves: eight cervical, twelve thoracic, five lumbar, five sacral, and one coccygeal pair. This division corresponds to the vertebral column, with the cervical region located at the neck, the thoracic region in the upper back, the lumbar region in the lower back, and the sacral region at the base of the spine. Each segment of the spinal cord is responsible for transmitting signals to and from different parts of the body.
