Spinal nerves. 7 pairs of cervical, 12 pairs of thoracic, 5 pairs of lumbar, 5 pairs of sacral, and 4 pairs of coccigeal spinal nerves.
The spinal nerve passes through the intervertebral foramen, which is a small opening formed by two adjacent vertebrae in the spine. The spinal nerve carries sensory and motor information between the spinal cord and the rest of the body.
The occipital bone surrounds the structure known as the foramen magnum, which is a large opening at the base of the skull through which the spinal cord passes.
The foramen magnum transmits the spinal cord, accessory nerves, vertebral arteries, and the anterior and posterior spinal arteries. The superior orbital fissure transmits oculomotor, trochlear, ophthalmic division of trigeminal, abducens, and ophthalmic veins. The optic foramen transmits the optic nerve and ophthalmic artery. And the jugular foramen transmits the glossopharyngeal, vagus, and accessory nerves, the internal jugular vein, and the sigmoid sinus.

The mandibular nerve passes through foaramen ovale of the spenoid bone. Blood passes through the foamen ovale of the heart of the fetus.

Sphenoid bone of the skull. It is the most interesting bone in the skull.
The large hole located between the body and the spinous process. The spinal cord passes through this foramen.
The medulla oblongata passes through the foramen magnum, a large opening at the base of the skull. It is the lowest part of the brainstem and helps regulate vital functions such as breathing, heart rate, and blood pressure.
The foramen magnum transmits the spinal cord, accessory nerves, vertebral arteries, and the anterior and posterior spinal arteries. The superior orbital fissure transmits oculomotor, trochlear, ophthalmic division of trigeminal, abducens, and ophthalmic veins. The optic foramen transmits the optic nerve and ophthalmic artery. And the jugular foramen transmits the glossopharyngeal, vagus, and accessory nerves, the internal jugular vein, and the sigmoid sinus.
