The major nerves that arise from the sacral region of the spine are the sciatic nerve, which is the largest nerve in the body, and the posterior femoral cutaneous nerve. These nerves provide sensory and motor innervation to the lower extremities.
The four main nerve plexuses are the cervical plexus, brachial plexus, lumbar plexus, and sacral plexus. These plexuses are intricate networks of nerves that arise from the spinal cord and supply various regions of the body with sensory and motor functions.
The cervical spinal nerves form the cervical plexus, the brachial spinal nerves form the brachial plexus, the lumbar and sacral spinal nerves form the lumbosacral plexus, and the sacral spinal nerves form the sacral plexus.
The brachial plexus is formed by the spinal nerves C5-T1, while the lumbosacral plexus is formed by the spinal nerves L1-S4. These plexuses are networks of nerves that supply motor and sensory innervation to the upper and lower limbs, respectively.

The branchial plexus is a network of nerves that innervates the muscles of the shoulder, arm, and hand. It allows for the movement and sensation of these parts of the body.
