The spinal cord is a mass of nervous tissue that extends inferiorly from the brain stem through the vertebral canal of the cervical and thoracic regions, ending around the T12 or L1 vertebra. It is a long tube about 18 inches (45 cm) in length and around half an inch (1 cm) in diameter at its widest point.

The spinal meninges are three membranes that surround the spinal cord – the dura mater, arachnoid mater, and pia mater. They contain cerebrospinal fluid, acting to support and protect the spinal cord.
