Spinal Cord ◼ Part of the CNS along with brain ◼ Contained within vertebral canal ◼ Extends from cranium to 1st-2 nd lumbar vertebrae ◼ Lumbar roots & sacral nerves for a “horse-like tail” called cauda equina ◼ 2 plexuses ◼ Brachial, lumbosacral
Nerves Each vertebrae has a nerve that exits either below or above it a 31 pairs of spinal nerves a8 cervical nerves 12 thoracic nerves a5 lumbar a5 sacral 1 coccygeal
