Facial Bone

The function of the facial bone is to protect our brain and other sensitive organs situated in our face like an organ of smell, sight, hearing, taste and equilibrium. The facial bone also provides attachment of muscles that is responsible for movement of the head and controlling our facial expression which may also play a role in understanding in a written language.

Facial Bone Anatomy

The facial bone composes of 14 bones that is:

1 vomer – it can be found in the midsagittal line of the head, and articulates with the sphenoid, the ethmoid, the left and right palatine bones, and the left and right maxillary bones.

2 Maxilla – it also known as the upper jaw. It is also a vital viscerocranium structure of the skull. The two maxillary bones are fused in midline by the intermaxillary suture to form the upper jaw.

1 Mandible – it is the lower jaw or known as jawbone. It is the largest, strongest and lowest bone in the facial bone. It forms the lower jaw and attached our teeth to hold in placed.

2 Nasal Bones – our nose is supported by the nasal bones. 

2 Palatine Bone – The palatine bone is a paired, L-shaped bone that forms part of the nasal cavity.

2 Lacrimal Bones – is a small and fragile bone of the facial bone. It is roughly the size of the little fingernail. It is located at the front part of the medial wall of the orbit.

2 Zygomatic Bones – it is called cheekbone or malar bone. It’s a diamond shaped bone below and lateral to the orbit, or eye socket, at the widest part of the cheek.

2 Inferior nasal conchae – it is one of the three paired nasal conchae in the nose. It extends horizontally along the lateral wall of the nasal cavity and consists of a lamina of spongy bone, curled upon itself like a scroll.
