Study Notes
Plexuses and Spinal Nerves
- The lumbosacral plexus is located in the lumbar and sacral regions of the vertebral column.
- The lumbosacral plexus is formed by the spinal nerves L1-S4.
- The brachial plexus and lumbosacral plexus have functions related to the transmission of motor and sensory information.
- The lumbar region has 5 pairs of spinal nerves (L1-L5).
- The sacral spinal nerves correspond to the sacrum region of the vertebral column.
- The cervical and lumbar regions give rise to the brachial plexus and lumbosacral plexus, respectively.
