Front 12

Inferior orbital fissure

Back 12

At the junction of the lateral wall and floor

Front 13

Suture

Back 13

And in movable joint in most cases in an adult skull that holds most skull bone together. Sutures in the skulls of infants and children, however, often are movable and function as an important growth center in the developing skull

Front 14

Coronal suture

Back 14

Unites the frontal bone and both parietal bones

Front 15

Sagittal suture

Back 15

Unite the two parietal bones on the superior midline of the skull. The saggital suture is so named because in the infant, before the bones of the skull are firmly united, the suture and the fontanels associated with it resemble an arrow

Front 16

Lambdoid suture

Back 16

Unite the two parietal bones to the occipital bone. This suture is so named because of its resemblance to the capital Greek letter lambda, sutural bones may occur within the sagittal and lambdoid sutures.

Front 17

Squamous sutures

Back 17

Unites the parietal and temporal bones on the lateral aspect of the skull

Front 18

Paranasal sinuses

Back 18

Cavities within certain cranial and facial bones near the nasal cavity. they are most evident in a sagittal section of the school. They are lined with mucous membranes that are continuous with the lining of the nasal cavities. secretions produced by the mucous membrane of the paranasal sinuses drain into the lateral wall of the nasal cavity.

Front 19

Which bones make up the sinus cavity?

Back 19

Frontal

Sphenoid

Ethmoid

Maxillae

Front 20

Anterior fontanelle

Back 20

The largest fontanelle, it is located at the midline among the two parietal bones and the frontal bone, and is roughly shaped like a daimond. And usually closes 18 to 24 months after birth.

Front 21

Posterior fontanelle

Back 21

Is located at the midline among the two parietal bones and the occipital bone. Because it is much smaller than the anterior fontanelle, it generally closes about two months after birth.

Front 22

Paired anterolateral fontanels

Back 22

Located laterally amongst the frontal, parietal, temporal, and sphenoid bones, are small and irregular in shape. Normally, they close about 3 months after birth

Front 23

Paired posterolateral fontanels

Back 23

Located laterally among the parietal, occispital, and temporal bones, are irregularly shaped. They begin to close one to two months after birth, but closure is generally not complete until 12 months.
