Verified step by step guidance
1
Understand the anatomy of the vertebral foramen: The vertebral foramen is the opening formed by the vertebral arch and the body of the vertebra. It is part of the vertebral canal, which houses the spinal cord and its protective coverings.
Identify the structures typically found within the vertebral foramen: The spinal cord, meninges (protective membranes surrounding the spinal cord), and sometimes the vertebral artery (in the cervical region) are found within the vertebral foramen.
Consider the intervertebral disc: Intervertebral discs are fibrocartilaginous cushions located between the bodies of adjacent vertebrae. They are not located within the vertebral foramen but rather between the vertebrae themselves.
Analyze the options: Compare each option to the structures typically found within the vertebral foramen. The intervertebral disc is not found within the vertebral foramen, as it is located between vertebrae.
Conclude which structure is not found within the vertebral foramen: Based on the analysis, the intervertebral disc is the structure that would not be found within the vertebral foramen.
