Vertebra e through which the
Spinal Cord passes. It is a process of the dorsal
Human Body Cavity . This canal is enclosed within the
Intervertebral Foramen of the
Vertebrae . In the intervertebral spaces, the canal is protected by the
Ligamentum Flavum posteriorly and the
Posterior Longitudinal Ligament anteriorly.
The outermost layer of the
Meninges , the
Dura Mater , divides the spinal canal into
Epidural and
Subdural regions. The subdural space is filled with cerebrospinal fluid and contains the structures of the
Spinal Cord enclosed by several additional membranes. The epidural space contains loose fatty tissue, and a network of large, thin-walled blood vessels called the .
