The Neurocranium!

Surrounding & protecting our brain. For Mnemonics & Key points read below!

*Overview⁣⁣  
⁣⁣  
The 8 bones of the Neurocranium form a major portion of the skull. ⁣⁣

We have two temporal bones, two parietal bones, a single occipital bone, sphenoid bone, ethmoid bone and the frontal bone.

*Key Points⁣⁣  
⁣⁣  
Occipital Bone - forms the base of skull at the rear of cranium. Connects with the first vertebra of the spinal cord and contains foramen magnum (opening of skull through which spinal cord passes as it enters vertebral column).
⁣⁣  
Temporal Bones - on the base and sides of the skull. Two processes originate: Zygomatic process (articulates with zygomatic bone of cheek) & the styloid process (several tongue muscles attach here) ⁣⁣  
⁣⁣  
Parietal Bones - make up the roof and sides of the skull.
⁣⁣  
Sphenoid Bone - middle of skull towards the front and forms the rear of the orbit. Butterfly shaped due to the wing-like processes. Interacts with numerous facial bones, ligaments & muscles. ⁣⁣  
⁣⁣ 
Ethmoid Bone - at the roof of the nose and between the orbits. Small bone separating the nasal cavity from the brain.  
⁣⁣
Frontal Bone - forms the front of the skull and divided into 3 parts: Squamous, Orbital & Nasal. ⁣⁣
