Lunate bone

Lunate Bone The Lunate or Lunar bone (lat. os lunatum) is a flat, wide bone that is located in the lateral (side) part of the cranial vault. Located in front and downward from the temporal fossa of the pyramid of the temporal bone, next to the pyramids of the temporal bones. It participates in the formation of the frontal and parietal fossa.

It has an eyelet for the attachment of muscles that push the tongue, and an oval opening near the edge of the skull for the passage of nerves and blood vessels to the brain stem. In front it ends with the frontal tubercle (mactugra), and behind it, freely passing through a small lens of the occipital bone, it enters the body of the sphenoid bone in the form of the sphenoid sinus.

The transverse and auricular branches of the maxillary nerve pass through the lunate bone, which connect with the auricular bone nerves, at the end of the branch they complete the merger with another branch
