Overview
Pathophysiology
Anotomy
- The spinal cord extends from the foramen magnum down to the level of the first and second lumbar vertebrae.[1][2]
- At L2 level spinal cord transforms into spinal roots and forms a cone-shaped structure called conus medullaris.
- The cord is protected by the vertebral column, which is mobile and allows for movement of the spine.
- It is enclosed by the dura mater and the vessels supplying it.
- The cord floats in the cerebrospinal fluid which acts as a buffer to movement and early degrees of compression.
- The cord substance contains a gray area centrally and is surrounded by white matter communication tracts, both ascending and descending.
