The sagittal suture is the longest suture in the skull and runs from the frontal bone, between the parietal bones, to the lambdoid suture. The lambdoid suture is the suture that forms between the parietal and occipital bones. There are no major sutures in the facial bones. 

The lacrimal bone is located in the orbit, nearest the nasal cavity. The sphenoid bone is located behind the eyes. The mandible makes up the lower jaw. Finally, the occipital bone is located in the posterior aspect of the skull.

The stapes, or stirrup, is the ossicle closest to the skull. It is the last bone in the "chain" of ossicles. The incus, also known as the anvil, is the middle bone. The malleus, or hammer, is the most distal bone from the skull.

The nasal conchae are curved shelves of bone found within the nasal cavity; they filter, humidify, and heat inhaled air. The maxillary sinuses are paired cavities found on either side of the nose. The ethmoid sinuses are small irregular cavities found between the eyes. The nasal septum is the structure that divides the nasal cavity into two halves. 

The hard palate is the bony palate that separates the two cavities; it is made of the palatine bone and the maxilla. The soft palate helps prevent food and drink from entering the nasal cavity. Teeth allow for the tearing and grinding of food into smaller pieces for easier digestion. The mandible is the lower jaw bone.

The sella turcica is part of the sphenoid bone, and houses the pituitary gland.

A fontanelle (or fontanel) is a normal feature of the infant skull. It comprises of soft membranous gaps (sutures) between the cranial bones that make up the infant's skull. These gaps allow for rapid stretching and growth as the developing brain grows faster than the surrounding bone can. There are 4 fontanels: the posterior, anterior, sphenoidal, mastoid. They close at different rates, however they are all closed by approximately 18-20 months of age. 

The human skull consists of the following bones: frontal, occipital, sphenoid, ethmoid, and paired parietal and temporal bones. The parietal and temporal bones are paired, while the others are not. The frontal bone is in the front of the skull, the occipital is in the back, the parietal and temporal bones are on the left and right sides with the parietal bones superior to the temporal bones.  

All of these are "holes" or foramina (plural of foramen) of the skull except the greater sciatic foramen which is located in the pelvis. Foramina allow for the passage of veins, nerves, and even muscles through bones. However, the hip is one of the few areas a muscle passes through a bone. The greater sciatic foramen allows for the passage of the piriformis muscle which takes up most of foramen. There are also several nerves such as the sciatic nerve and veins such as the gluteal vein.

The occipital bone is the bone responsible for forming the back of the skull and parts of the base of the skull. The other bones listed form other parts of the skull.
