The complex anatomy of the cranium and facial bones can be intimidating. the task of identifying these structures can be simplified. It is important to understand the normal anatomy of the cranium and facial bones to identify pathologic disorders and injuries that may occur within this area.

This course demonstrates the normal anatomy of the cranium , facial bones , temporomandibular join , paranasal sinuses , and the orbit .

O B J E C T I V E S

• Differentiate between the three cranial fossae.

• Identify the location and unique structures of each

cranial and facial bone.

• Identify the structures of the external, middle, and

inner ear, and describe their functions.

• Identify the cranial sutures.

• Describe the six fontanels in the infant cranium.

• Describe the structures that constitute the

temporomandibular joint.

• Identify the location of each paranasal sinus and the

meatus into which it drains.

• Identify the bones that form the orbit and their

associated openings.

• Describe the structures that constitute the globe of

the eye.

• List the muscles of the eye, and describe their

functions and locations.
