Document Summary

Contains neural circuits that control some of your quickest reactions to environmental changes. The spinal cord is continuous with the brain and together they constitute the central nervous system. This is how we respond to the environment; which will control a lot of your motor activity. Once it is received it is going to relay in to the appropriate nerves. Spinal meninges- three protective connective tissue coverings that. Very well protected but not as protected as our brain circle the spinal cord. Between dura mater and the wall of vertebral canal. Denticular ligament- triangular shaped membranous extensions of the pia mater that suspend the spinal cord in the middle of its dural sheath. Extension of pia mater that holds and anchors the layers to the spinal cord. The spinal cord is also protected by a cushion of fat and connective tissue located in the epidural space; a space between the dura mater and the wall of the vertebral canal.
