Cranial and Facial Bones
There are total 206 bones in human body. Out of these bones, 22 are of the human skull. This is a combination of cranial and facial bones. Our facial skeleton does not include teeth and the cartilage that gives shape to our nose. The human skull is full of small holes. These holes are known as foramina. The largest foramina of the skull are at the base of the skull, in the occipital bone. Most of the people confuse braincase and skull cap with each other but both of them are different. Cranial bones give protection to our brain. Facial bones do the work of forming the mechanical framework of the face and also provide attachment for some muscles for facial expressions.

- We use our temporomandibular joint to open or close our mouth.
- The human skull looks different on the basis of gender and racial heritage.
- The facial skeleton protects the sense organs of smell, sight, and taste.
- 8 cranial bones include 1 Ethmoid bone, 1 Frontal bone, 1 Occipital bone, 1 Sphenoid bone, 2 Parietal bones, and 2 Temporal bones.
- 14 facial bones include 1 Mandible, 1 Vomer, 2 Inferior Nasal Conchae, 2 Lacrimal bones, 2 Maxillae, 2 Nasal bones, 2 Palatine bones, and 2 Zygomatic bones.
- The Ethmoid and the Palatine bones are the only skull bones that you cannot feel by touching your head or face.
- The non-movable interlocking joints that join skull bones together are known as Sutures.
- Sutural bones are very small bones that develop within sutures.
- The mucus-lined cavities inside cranial and facial bones that surround the nasal cavity are known as sinuses.
- The Occipital bone forms the base of the skull.
- A thin and roughly triangular plate of bone on the floor of the nasal cavity is known as Vomer.
- Mandible, also known as the lower jaw bone is the largest and strongest facial bone.
