What are the parts of the frontal bone?
The frontal bone consists of six main parts: the squamous part, nasal part, two orbital plates and two zygomatic plates. The main function of the frontal bone is to create the smooth curvature of the forehead and to provide protection for the frontal lobe of the brain.
What does the frontal bone contain?
The frontal bone has an involvement in the formation of the pterion, a joining of four cranial bones: frontal, sphenoidal, parietal, and temporal. Lastly, the anterior aspect of the frontal bone contains two frontal sinuses, each superior to the orbital roof.
Where is the supraorbital ridge located?
frontal boneThe supraorbital ridge, also known as the supraorbital margin or superciliary arch is the superior margin of the bony orbit. Part of the frontal bone, the supraorbital ridge contains the supraorbital foramen (or notch).
What exits the supraorbital foramen?
1 Supraorbital Nerve. The supraorbital nerve is the direct continuation of the frontal nerve. It leaves the orbit through the supraorbital notch, or the supraorbital foramen.
What is the supraorbital?

What cranial nerve goes through the supraorbital foramen?
Supraorbital nerve block 11.4). The supraorbital (or frontal) nerve is one of the terminal branches of the ophthalmic division of the Vth cranial nerve. It emerges from the orbit accompanied by the artery through the supraorbital foramen in the supraorbital process.
Which bone forms roof of mouth and floor of nasal cavity?

The infraorbital foramen permits the passage of three structures: Infraorbital nerve (a branch of the maxillary division ...
Where is the infraorbital foramen located?
Infraorbital foramen. The infraorbital foramen is located in the maxillary bone. It is the anterior opening of the infraorbital canal, which is the anterior continuation of the infraorbital groove, which course through the floor of the orbit. The canal may reside entirely in the maxillary sinus, suspended from the sinus roof by a mesentery.
What nerve is in the foramen?
