Answer 2

Hollow body that encloses maxillary sinus/antrum, shaped like a pyramid lying on it’s side

Question 3

Describe the Mandible

Answer 3

It’s the largest and strongest facial bone.

The mandible forms the lower jaw, and occupies the lower third of the facial skeleton, it’s the bone into which LWR teeth are attached.

Question 4

What is the composition of the mandible?

Answer 4

Composed of two components - Body & Ramus

Question 5

Describe the Body of the Mandible

Answer 5

Body is curved like a horse shoe

Encompases the Alveolar Process which is created by a thick buccal and thin lungual plate of bone.

Question 6

Describe the Ramus of the Mandible

Answer 6

Ramus there are two vertical Rami, projects upwards, one from each posterior end of the body.

Meet the body of the mandible at the angle of the mandible

Question 7

Where is the retromolar fat pad located?

Answer 7

Towards the posterior of the mandiublar arch, after the last molar.

Question 8

Where is the Maxillary Tuberosity located?

Answer 8

Towards the posterior of the maxillary arch, the gum behind the last molar.

Question 9

What is the alveolar process?

Answer 9

The alveolar process contains the socket which teeth are held in by periodontal ligament.

Answer 11

The oral cavity Proper

Question 12

Question 16

Describe the Vestibule

Answer 16

The space between the lips and cheeks, and the teeth and alveolar.

Continuation of mucosa covering the alveolar to the lips and cheek create a culcas called the vestibule.

The sulcas can be interrupted by folds of mucosa called the fernum.

Question 17

How many and where are the Oral Vestibules located?

Answer 17

2^,

Maxillary labial Frenum

Mandibular Labial Frenum

Question 18

What is the Labial Mucosa and Buccal Mucosa

Answer 18

Lines the inside of the mouth.

Consists of epithelium and connective tissue

Question 19

Gingiva can first be divided into 3 sections, name them

Answer 19

Alveolar mucosa

Mucogingival junction

Attached gingiva

Question 20

Answer 20

Alveolar mucosa

Mucogingival junction

Attached gingia

Marginal gingiva

Interdental gingia (papilla)

Sulcus (inside)

Question 21

Describe the Palate

Question 22

Where can you locate Incisive Papilla?

Answer 22

It’s present at the beginning of the hard palate behind the central incisors.

Question 23

What is directly posterior to this papilla?

Answer 23

Directly posterior to this papilla are palatine rugae, which are firm, irregular ridges of tissue.

Question 24
