There are two joints at the base of the skull:
- a condyloid joint between the occipital bone of the skull and the first (C1) vertebra, the atlas.
- a pivot joint located between the C1 and C2 cervical vertebrae (atlas and axis).
occipital bone
occiput
Occipital bone
The bone is called the occipital bone which forms most of the skulls posterior wall and base. It articulates with anteriorly with the paried parietal and temporal bones via the lambdoid and occipitomastoid stures. It also joins the sphenoid bone in the cranial floor.
sphenoid-A compound bone with winglike processes, situated at the base of the skull.
*american Heritage Dictionary
The sphenoid bone is one of the skull bones and is located relatively deep within the skull. It is only very slightly visible from an exterior view of the skull. Looking side on to a skull it is right between the temporal bone and the zygomatic bone, in other words it is the small section beneath the Pterion. It is also visible when looking into the orbit (with the eye removed) as the bone with the superior orbital fissure through it.
The Sella turcica is found on the surface of the sphenoid bone, at the base of the skull. It's where we find the pituitary gland.
The temporal bone is located in the skull, and the skull consists of flat bones so yes, it is a flat bone
