a.

Foramen

Canal

c.

Sulcus

d.

Fissure

Feedback

A

A foramen is a short windowlike opening in bone.

B

A canal is a tubelike opening in bone.

C

A sulcus is a shallow depression or groove on bony surface and NOT an opening in bone.

D

A fissure is a narrow cleftlike opening in bone.

a.

Hyoid bone

b.

Mandible

c.

Palatine

d.

Vomer

Feedback

A

Even though the hyoid bone is movable and has no bony articulations, it is a bone located in the neck and NOT the skull.

B

The mandible is the only skull bone that moves; it moves at the temporomandibular joint. Within this joint, the mandibular condyle moves within the articular fossa of the temporal bone.

C

The palatine bone may be a skull bone, but it does NOT move.

D

The vomer may be a skull bone, but it does NOT move.

a.

Anterior view

b.

Inferior view

c.

Lateral view

d.

Superior view

Feedback

A

It is difficult to see the squamosal suture on the lateral skull surface from an anterior view.

B

It is difficult to see the squamosal suture on the lateral skull surface from an inferior view.

C

The squamosal suture is the suture between the parietal bones and temporal bones on each side of the skull. This suture is BEST viewed from the lateral view.

D

It is difficult to see the squamosal suture on the lateral skull surface from a superior view.

a.

Cribriform plate

b.

Infraorbital foramen

c.

Inferior orbital fissure

d.

Superior orbital fissure

Feedback

A

The cribriform plate is a passageway for olfactory nerves from the nasal cavity to the brain.

B

The infraorbital foramen is located inferior to the orbit on the facial surface of the maxilla.

C

The inferior orbital fissure connects the orbit with both the infratemporal and pterygopalatine fossae and NOT the cranial cavity.

D

The superior orbital fissure is a slitlike opening between the lesser and greater wings of the sphenoid bone and serves as a passageway for blood vessels and nerves from the cranial cavity into the orbit, thus connecting the two.

a.

External auditory meatus

b.

Jugular notch

c.

Foramen spinosum

d.

Stylomastoid foramen

Feedback

A

The external acoustic meatus is the short external canal that leads to the tympanic cavity.

B

The jugular notch, formed by the articulation of temporal and occipital bones, is associated with the jugular vein and the ninth, tenth, and eleventh cranial nerves.

C

The foramen spinosum is more posterior and is associated with the middle meningeal artery.

D

The seventh cranial nerve enters the temporal bone through the internal acoustic meatus, travels within the temporal bone, and exits through the stylomastoid foramen onto the face.

a.

Hypoglossal canal

b.

Foramen ovale

c.

Foramen spinosum

d.

Stylomastoid foramen

Feedback

A

The hypoglossal canal can be viewed from both inferior and superior aspects of the skull.

B

The foramen ovale can be viewed from both inferior and superior aspects of the skull.

C

The foramen spinosum can be viewed from both inferior and superior aspects of the skull.

D

The stylomastoid foramen is NOT visible from a superior view of the skull and can ONLY be observed from an inferior view of the skull. It is located between the mastoid process and the styloid process on the inferior surface of the petrous part of the temporal bone.

a.

Internal acoustic meatus

b.

Foramen rotundum

c.

Foramen spinosum

d.

Hypoglossal canal

Feedback

A

The internal acoustic meatus is located on the superior internal surface of the temporal bone and is associated with both the seventh and eighth cranial nerves.

B

The foramen rotundum is located within the sphenoid bone and is associated with the maxillary nerve or second division of the fifth cranial nerve.

C

The foramen spinosum is located within the sphenoid bone and is associated with the middle meningeal artery.

D

The twelfth cranial nerve passes through the hypoglossal canal, an opening in the skull that is located in the occipital bone on each side of the foramen magnum.

a.

Serves as an attachment for the muscles of mastication

b.

Serves as an attachment for muscles involved in swallowing

c.

Serves as a landmark observed on maxillary posterior periapical radiographs

d.

Serves as a landmark observed on mandibular posterior periapical radiographs

Feedback

A

The pterygoid process is an attachment for both the lateral and medial pterygoid muscles, which are two muscles of mastication.

B

The pterygoid process does NOT provide attachment for the muscles involved in swallowing.

C

The pterygoid process is NOT a landmark usually observed on maxillary periapical radiographs.

D

The pterygoid process is NOT a landmark observed on mandibular periapical radiographs.

a.

Crista galli of the ethmoid bone

b.

Frontal sinuses of the frontal bone

c.

Cribriform plate of the ethmoid bone

d.

Perpendicular plate of the ethmoid bone

Feedback

A

The crista galli is the vertical projection of the ethmoid bone into the cranial cavity. It is an area of attachment for the meninges.

B

The frontal sinuses of the frontal bone do NOT have openings for passage of the olfactory nerves to the brain.

C

The cribriform plate is the superior horizontal part of the ethmoid bone that is perforated for passage of olfactory nerves for the sense of smell.

D

The perpendicular plate of the ethmoid bone forms part of the nasal septum.

a.

Perpendicular plate of the ethmoid bone

b.

Inferior nasal conchae

c.

Lacrimal bones

d.

Nasal bones
