|---|---|
| Roof of the nasal cavity. Contains foramina that allow the olfactory nerves (cranial nerve I) to pass from the nose to the brain. | Cribriform Plate |
| Cavity within in the bone that is lined with mucosa and open to the exterior. It lightens the skull and alters vocal quality | Ethmoidal Sinus (labyrinth) |
| Cavity within in the bone that is lined with mucosa and open to the exterior. It lightens the skull and alters vocal quality | Frontal Sinus |
| Foramen through which the spinal cord passes to connect with the brain. | Foramen Magnum |
| Openings through which the hypoglossal nerves (cranial nerve XII) pass. The hypoglossal nerves carry signals to and from the tongue | Hypoglossal Canal |
| Articular surface between the occipital bone and the atlas vertebra | Occipital Condyle |
| Opening through which a branch of the trigeminal nerve (cranial nerve V) passes. This branch of the trigeminal nerve carries sensory and motor stimuli to the jaw | Foramen Ovale |
| Opening through which a branch of the trigeminal nerve (cranial nerve V) passes. This branch of the trigeminal nerve carries sensory input from the face | Foramen Rotundum |
| Opening through which blood vessels pass that feed membranes surrounding the CNS | Foramen Spinosum |
| Openings through which the optic nerves (cranial nerve II) pass. The optic nerves transmit visual stimuli | Optic Canals |
| Structure that holds the pituitary gland | Sella Turcica |
| Cavity within the bone that is lined with mucosa and open to the exterior. It lightens the skull and alters vocal quality. | Sphenoidal Sinus |
| Opening through which oculomotor, trochlear, trigeminal, and abducens nerves (cranial nerves III, IV, V, and VI) pass. Most of these nerves enable movement of the eyes. | Superior Orbital Fissure |
