Seven bones contribute to the orbits. They are the frontal, sphenoid, zygomatic, maxilla, palatine, lacrimal, and ethmoid bones. The vomer is not a contributor to the orbits.

Which of the following bones does NOT form a part of the orbits of the eyes?

Inferior aspect of the skull, mandible removed

Bones of the Skull

The role of the cranium is to enclose and protect the brain. The facial skeleton, which comprises the rest of the skull, does things such as anchor facial muscles and secure the teeth.

provide openings for food and air passage

The role of the cranium is to __________.

The frontal sinuses are located lateral to the glabella.

The frontal sinuses are located __________.

Except for the mandible joint, all skull bones are connected by interlocking joints called sutures.

A joint between skull bones is called a __________.

The midline central projection of the ethmoid is the crista galli.

The crista galli is a projection from which bone?

The lacrimal fossa is a passageway for tears to enter the nasal cavity. It contains a mucous membrane passageway that includes the lacrimal sac.

What would you find located in the lacrimal fossa?

The sella turcica of the sphenoid bone surrounds the pituitary gland.

Which of the following bones would most likely be involved in surgery to remove a tumor on the pituitary gland?

The temporal bone contains the mandibular fossa that receives the condyle of the mandible and forms the temporomandibular joint.

Which of the following cranial bones receives the condyle of the mandible?

How do the relative proportions of the cranium and face of a fetus compare with those of an adult skull?

The cranial base is part of the cranial floor, whereas calvaria is another term used for the cranial vault, or roof.

The cranial cavity is the space occupied by the brain inside the cranium, whereas calvaria is another term used for the cranial vault, or roof.

The anterior cranial fossa is part of the cranial floor, whereas calvaria is another term used for the cranial vault, or roof.

The calvaria of the skull is another name for the __________.

The vomer is a facial bone. The rest are cranial bones.

The maxillary bones (maxillae) form the central part of the facial skeleton. The only facial bone that does not articulate with the maxillae is the mandible.

The only bone of the facial skeleton that does NOT articulate with the maxillae is the __________.

Dentists inject lidocaine into the mandibular foramen to prevent pain in the lower teeth.

Where would a dentist inject lidocaine to prevent pain in the lower teeth?

The mandible is the only bone in the skull that is not connected to other bones by sutures and is therefore the only mobile bone in the skull.

Sutures connect all the bones of the skull EXCEPT the __________.

Name the cranial and facial bones and compare and contrast the functions of the cranial and facial skeletons.
