The spinal cord passes through which of the following?

The spinal cord passes through the vertebral foramen, which is the large opening in each vertebra that aligns to form the spinal canal. This structure is specifically designed to protect the spinal cord as it runs down the vertebral column. The vertebral foramina are essential because they create a continuous channel through which the spinal cord can extend from the base of the skull down to the lower back.

In contrast, the intervertebral foramen represents the openings between the vertebrae where the spinal nerves exit the spinal column. The spinal canal is a larger space that encompasses the vertebral foramen but refers to the passage containing the spinal cord and related structures. The anterior sacral foramen refers to openings in the sacrum, primarily for the exit of sacral nerves, and is not involved in the passage of the spinal cord itself. Understanding these anatomical distinctions is crucial for recognizing the protective pathways and structures surrounding the spinal cord.
