Answer 16

the dorsum (top), sides, and undersurface of the tongue

Question 17

The internal jugular vein, which corresponds to the common carotid artery, empties into___

Answer 17

Question 18

How many pairs of cranial nerves are connected to the brain?

Answer 18

twelve pairs

Question 19

Mandibular Division of the Trigeminal Nerve:

Answer 19

1. The buccal nerve
   Supplies branches to the buccal mucous membrane and mucoperiosteum of the mandibular molar teeth.
2. The lingual nerve
   Supplies the anterior two thirds of the tongue and gives off branches to supply the lingual mucous membrane and mucoperiosteum.
3. The inferior alveolar nerve
   Further subdivides into the mylohyoid nerve, mental nerve, incisive nerve, and small dental nerves that supply the molar and premolar teeth, alveolar process, and periosteum.

Question 20

The trigeminal nerve (V) is the primary source of innervation for the oral cavity
The trigeminal nerve subdivides into three main branches:

Answer 20

1. Maxillary
2. Mandibular
3. Ophthalmic

Question 21

What Roman numeral represents the trigeminal nerve?

Answer 21

V

Question 22

is the primary source of innervation for the oral cavity

Answer 22

The trigeminal nerve (V)

Question 23

Maxillary Division of the Trigeminal Nerve divides into:

Answer 23

1. Nasopalatine nerve
   Supplies the maxillary anterior teeth
2. Greater palatine nerve
   Supplies the mucoperiosteum
3. Anterior superior alveolar nerve
   Supplies the central, lateral, cuspid teeth, gingiva and periodontal membranes.
4. Middle superior alveolar nerve
   Supplies the maxillary 1st and 2nd premolars, and the MB (mesiobuccal) root of the maxillary 1st molars
5. Posterior superior alveolar nerve
   Supplies the roots of the maxillary 1st molars, 2nd and 3rd molars

Question 24

The major sites of lymph nodes include:

Answer 24

Cervical (in the neck). The dental professional must palpate deep around the sternocleidomastoid muscle to feel the deep cervical lymph nodes.

Axillary (under the arms)

Inguinal (in the lower abdomen)

Question 25

The lymph nodes of the head are classified as

Answer 25

superficial (near the surface) or deep

Question 26

Lymphadenopathy

Answer 26

When a patient has an infection or cancer in a particular region, the lymph nodes in that region will respond by increasing in size and becoming very firm.
Lymphadenopathy results from an increase in both the size of each lymphocyte and the overall cell count in the lymphoid tissue
With an increase in the size and number of lymphocytes, the body is better able to fight the disease.

Question 27

Cells are the body’s main defense

Answer 27

Lymphocyte

Question 28

The paranasal sinuses are air-containing spaces within the skull that communicate with the nasal cavity
The functions of the sinuses include:

Answer 28

1. Producing mucus
2. Making the bones of the skull lighter
3. Providing resonance that helps produce sound
   The sinuses are named for the bones in which they are located

Question 29

Kind and Characteristics of Paranasal Sinuses

Answer 29

The maxillary sinuses are the largest of the paranasal sinuses.

The frontal sinuses are located within the forehead, just above both eyes.

The ethmoid sinuses are irregularly shaped air cells separated from the orbital cavity by a very thin layer of bone.

The sphenoid sinuses are located close to the optic nerves, where an infection may damage vision.

Question 30

During what type of dental examination are lymph nodes palpated?

Answer 30

Extraoral examination

Question 31

The name of inflammation of the sinus

Answer 31

sinusitis
