Through which opening does the spinal cord pass from the brainstem into the spinal column?

Explanation:
The passage from brainstem to spinal cord goes through the foramen magnum. This large opening at the base of the skull in the occipital bone allows the medulla oblongata to continue downward as the spinal cord, and also transmits surrounding protective membranes and vessels. The other openings have different roles: foramen ovale transmits the mandibular nerve, jugular foramen transmits cranial nerves IX–XI and the internal jugular vein, and the carotid canal transmits the internal carotid artery.
