Question 12

Zygomatic process

Answer 12

Process extends from the frontal, temporal, and maxilla bones. These are also known as cheekbones

Question 13

Palatine process

Answer 13

Process rests on the hard palate

Question 14

Temporal process

Answer 14

Process extends from the temporal bone to the zygomatic bone

Question 15

Frontal process

Answer 15

Process extends from the frontal bone to the zygomatic bone

Question 16

Coronoid process

Answer 16

Process is the anterior portion of the ramus

Question 17

Condyloid process

Answer 17

Process is the posterior portion of the ramus

Question 18

Alveolar process

Answer 18

Process contains sockets that hold the roots of the teeth

Question 19

Sutures

Answer 19

The intermaxillary suture joins the two maxillary bones from the nasal cavity inferiorly to between the maxillary central incisors. The medial palatine suture joins the two maxillary bones at the middle of the hard palate

Question 20

Nasion

Answer 20

The point on the skull corresponding to the middle of the nasofrontal suture at the bridge of the nose

Question 21

Maxillary tuberosity

Answer 21

Large rounded process located posterior to the third molar area. You can feel your maxillary tuberosity with your tongue behind your upper molars

Question 22

Middle and inferior turbinates

Answer 22

Bones shaped like a top inside the nasal cavity which increase the interior surface of the nose

Question 23

Glenoid fossa

Answer 23

A depression in the temporal bone which articulates with the condyle of the mandible

Question 24

External auditory meatus

Answer 24

The passage to the external opening of the ear canal

Question 25

Sigmoid notch

Answer 25

Separates the condyle from the coronoid on the ramus

Question 26

Ramus

Answer 26

Upright portion of the mandible

Question 27

Mylohyoid ridge

Answer 27

Located on the lingual surface of the mandible

Question 28

Oblique ridge

Answer 28

Located on the facial surface of the mandible

Question 29

Mandibular notch

Answer 29

Located anterior to the angle of the mandible

Question 30

Angle of the mandible

Answer 30

The point of the mandible where the ramus ascends

Question 31

Mandibular symphysis

Answer 31

Midline of the body of the mandible (centre of the chin)

Question 32

Border of the mandible

Answer 32

The under surface of the jawbone

Question 33

Retromolar area

Answer 33

The area posterior to the molars on the mandible. Find this area with your tongue behind your lower molars

Question 34

Hyoid bone

Answer 34

Not one of the bones of the face or skull, yet important to mouth structures. It is suspended from the styloid process of the temporal bone and functions as a primary support for the tongue and associated muscles. Shaped like a horseshoe with bilateral projections called the Greater and Lesser Horns. Commonly known as the “Adam’s Apple”
