The correct word is thecal sac which is located witin the spinal vertebra. It is made up of a mixture of pia-mater-wrapped lumbar, sacral and coccygeal nerve roots and it protects these roots. The nerve roots of the thecal sac float freely in cerebral spinal fluid (CSF) which provides both protection and nutrition for the roots.
