This bone forms the forehead, the roof of the orbital cavity (eye socket), and the root of the nose. A newborn has a frontal bone that consists of two parts, separated by the frontal suture. However, the parts fuse to form a single bone, by the time a child is eight years old.
One bone from each side joins behind the frontal bone to form the sides and the roof of the cranium. There are 2 parietal bones, and each bone is roughly quadrilateral in shape.
There are 2 temporal bones in all, one on each side below the parietal bones. The temporal bones are located lateral to the temporal lobes of the brain, and each bone consists of five parts.
This is a single bone that is present at the back and lower part of the cranium, just behind the parietal and temporal bones. It has an oval aperture, known as the foramen magnum, through which the spinal cord enters the skull. Vertebral arteries, spinal nerves and ligaments that join the skull to the vertebrae, pass through this aperture.
This is a single bone that is situated at the base of the skull in front of the temporal bones and basilar part of the occipital bone. It’s shape resembles that of a butterfly, and it is one of the seven bones that form the orbital cavity or eye socket.
This is a light and spongy bone that is situated in the anterior part of the base of the cranium. It lies between the two orbits, at the roof of the nasal cavity, separating the brain from the nasal cavity. It is one of the seven bones that form the orbital cavity, and consists of three parts.

This is the lower jawbone, and is known as the inferior maxillary bone. It is U-shaped and is the largest and strongest bone of the face. The mandible of a newborn consists of two halves that fuse at the mental symphysis during the first year. Each half of the mandible has a horizontal body and a vertical ramus at the posterior end of the body. The...
The maxilla, or the upper jawbone, holds the teeth of the upper jaw, and forms the walls of the orbital cavity. It also contributes to the roof of the oral cavity, and the lateral walls and floor of the nasal cavity. The mandible is actually two bones that are fused along the palatal fissure. Failure of fusion of the two bones before birth, can lea...
The human skeleton is the internal framework of the human body. It is composed of around 270 bones at birth – this total decreases to around 206 bones by adulthood after some bones get fused together. [1]
