Final answer:
FALSE. The foramen magnum marks the border between the medulla oblongata and the cranial cavity, not the spinal cord.
Step-by-step explanation:
The foramen magnum is a large opening at the base of the skull through which the spinal cord passes, connecting the brain to the spinal canal. In Latin, "foramen magnum" translates to "large hole" or "great foramen." This opening is a critical anatomical structure as it allows communication between the brain and the spinal cord.
The foramen magnum marks the border between the medulla oblongata and the cranial cavity, not the spinal cord. The foramen magnum is a large opening in the base of the skull through which the spinal cord emerges and the vertebral arteries enter the cranium.
