The occcipital bone makes up the posteroinferior aspect of the cranium.

Question 6

The sphenoid bone is an unpaired butterfly shaped bone that forms the posterior aspects of the eye sockets and internal cranial structures.

Question 7

Question 14

Identify these bones and describe their position:

Answer 14

The paired zygomatic bones (left and right) form the cheekbones and join the temporal and maxillary bones.

Question 15

Identify these bones and describe their position:

Answer 15

The paired palatine bones (left and right) form the posterior part of the hard palate.

Question 16

Identify these bones:

Answer 16

Paired inferior nasal conchae (left and right) are small bones found in the nasal cavity.

Question 17

Identify this bone:

Answer 17

Question 20

What keeps the brain from freely moving around the cranial cavity?

Answer 20

A membrane anchors it to the Crista galli on the Ethmoid Bone.

Question 21

Which bones is the nasal septum comprised of?

Answer 21

The nasal septum is comprised partly of the ethmoid bone, a small bone called the vomer and the nasal cartilage. There are three extensions of bone into the cavity on each side, referred to as the nasal conchae.

Question 22

Answer 22

Vomer Conchae (2) Nasal (2) Maxilla (2) Mandible Palatine (2) Zygomatic (2) Lacrimal (2)
