The neck has distinct anatomical boundaries: Superior Boundary: The base of the skull, including the mandible and occipital bone.; Inferior Boundary: The clavicles (collarbones), sternum, and C7 vertebra (seventh cervical vertebra).; Posterior Boundary: The nuchal line of the skull and cervical spine.

The skull base and vault collectively form the neurocranium. The base of the skull is a bony diaphragm composed of a number of bones - from anterior to posterior:

To find the base skull sinus location, look at the occipital sinuses and other cavities. They are in the back of the skull, near where the skull meets the neck. Studies like MRI and CT scans show us where these sinuses are. They help doctors see the sinuses clearly. The occipital sinuses are near the foramen magnum, a key hole for the brainstem.
