Foramen magnum
A large open in which the spinal cord passes through. (Latin translation is "big hole")
External auditory meatus
Ear passage (meatus means passageway)
Occipital bone
Forms the back and base of the skull and is the cradle for the brain. It articulates with C1 (atlas), the parietal bones and temporal bones.

Parietal bones
These bones articulates with the temporal, occipital, and frontal bones.
Parietal bones
These bones make up the superior portion of the sides and back of the cranium 2/3 of the roof of the skull.
Frontal eminences
These of the prominences on the upper part of the four head. They can vary in size, maybe asymmetrical and may be continuous.
Temporal bone
This bone creates the inferior portion of the sides and the base of the skull and articulate with the parietal and occipital bone.
Frontal bone
This bone forms the four head and anterior portion of the roof of the skull
Glabella
This is a small smooth elevation which lies between the supercilliary arches, located immediately above the root of the nose.
External auditory meatus
This is the most accurate location of the ear and it's protected by a small flap of skin called the tragus
Squama
This is the vertical portion of the temporal bone, it is the anterior and superior portion of the bone.
Supercilliary arches
Visa located above the eyebrow arches
Occipital, parietal, Temporal, frontal.
