Final answer:
The surgery involves the removal of vertebrae to access the spinal cord, which is a bundle of nerve tissue protected by the vertebral column.
Step-by-step explanation:
Surgery involving the spinal cord often requires the removal of vertebrae to allow for clear visibility and access to the spinal cord. The spinal cord is a thin, tubular bundle of nervous tissue that is protected by the vertebrae and plays a Crucial role in connecting the brain with the peripheral nervous system. It extends from the brainstem down the back to the pelvis.
The vertebral column, or spinal column, is composed of 26 bones that include the 24 vertebrae, as well as the sacrum, and the coccyx. Each vertebra has a large central hole for the spinal cord to pass through, while the spinal nerves exit through notches on each side of the vertebrae. The role of the vertebral column is to protect the spinal cord and to support various body structures.
