Verified step by step guidance

Understand the anatomy of the spinal cord: The spinal cord is a cylindrical structure that serves as a communication pathway between the brain and the rest of the body. It is protected by the vertebral column and extends from the brainstem to a specific vertebral level.

Identify the starting point of the spinal cord: The spinal cord begins at the foramen magnum, which is the large opening at the base of the skull where the brainstem transitions into the spinal cord.

Determine the ending point of the spinal cord: The spinal cord does not extend the entire length of the vertebral column. In adults, it typically ends at the level of the L1-L2 vertebrae, forming the conus medullaris.

Recognize the significance of the conus medullaris: Below the conus medullaris, the spinal cord transitions into a bundle of nerve roots called the cauda equina, which continues within the vertebral canal.

Match the correct vertebral level: Based on the anatomical information, the spinal cord extends from the foramen magnum to the L1-L2 vertebral level, which is the correct answer to the question.
