Diagram of spine and nerves. The vertebrae which stack like spools of thread support the back and protect the spinal cord. Between every two vertebral bones two nerves exit the spinal canal. The spinal cord is an extension of the central nervous system cns which consists of the brain and spinal cord. Anatomically the spinal cord runs from the top of the highest neck bone the c1 vertebra to.
Lower back issues can put pressure on the lumbar spine nerves and create. For most spinal segments the nerve roots run through the bony canal and at each level a pair of nerve roots exits from the spine. If there is a ruptured disc it will pinch the nerve. Many of the peripheral nerves are named after the part of the spine where they join the spinal cord.
The spine anatomy is a complex structure. There are cervical thoracic and lumbar nerves. Similarly a damaged facet joint can also press on a nerve. Many of the nerves of the peripheral nervous system or pns branch out from the spinal cord and travel to various.
C6 nerve root at c5 c6 segment. Cervical spine nerve roots. The nerves exit right behind the disc and directly in front of the facet joint. The spinal cord begins at the base of the brain and extends into the pelvis.
In the neck the nerve root is named for the lower segment that it runs between eg. The spinal cord begins at the bottom of the brain stem at the area called the medulla oblongata and ends in the lower back as it tapers to form a cone called the conus medullaris.
