Study Notes
Spinal Roots and Nerves
- Each spinal root is composed of multiple rootlets, with a total of 8-10 rootlets in each spinal root.
- The spinal cord gives rise to 31 pairs of spinal nerves.
- The cervical region of the spinal cord supplies the upper limbs.
- The conus medullaris, the tapered inferior end of the spinal cord, ends at the level of the first or second lumbar vertebra.
- Spinal nerves are mixed nerves, carrying both motor and sensory information.
- The total number of spinal nerves that the spinal cord gives rise to is 31 pairs.
Spinal Cord Regions
- The sacral region of the spinal cord lacks dorsal roots.
- The cauda equina originates from the lumbar region of the spinal cord.
Spinal Cord Structure
