Neurocranium
Neurocranium (note: diagram uses the term "cranial bones" in the more narrow sense.)
Base of skull
Gray's	subject #30 128

The neurocranium is the upper portion of the skull.

It includes the following bones:

• Ethmoid bone
• Frontal bone
• Occipital bone
• Parietal bone
• Sphenoid bone
• Temporal bone

The term "cranium" can be ambiguous, in that it can refer to the neurocranium, or the neurocranium and the Facial skeleton.
