Orofacial Anatomy II Final Exam Review
1. Which teeth do not drain into the submandibular lymph nodes? ans
Mandibular incisors & maxillary 3rd molars
2. Where are the palatine tonsils located, between what tissues? ans Round
mass- es between the anterior fauce (formed by palatoglossus muscle) & posterior fauce
(formed by palatopharygeus muscle) on each side
3. - Describe healthy lymph nodes?
- Can you see all of them on an extraoral exam? ans - Usually small, soft, free
or mobile in the surrounding tissue
- Cannot be visualized or felt when palpating their usual location during an extra oral
examination of the head & neck
4. - Afferent vessel goes from where to where?
- Efferent vessel goes from where to where?
- In which direction in lymph nodes ans - Afferent Vesselans Lymphatic vessel
with lymph flowing into lymph node
- Efferent Vesselans Lymphatic vessel with lymph flowing out of the lymph node from
the nodes hilius
5. Lymphatic vessels have - similar to . Which allow for
one-way flow ans - One way valves
- Veins
6. Where is the thymus gland located? ans - In the thorax (chest) & the anterior region
of the base of the neck, inferior to the thyroid gland
- The gland is also superficial & lateral to the trachea & deep to the sternum & origins of the
sternohyoid & sternothyroid muscles
7. - Where are your posterior auricular, anterior auricular & superficial parotid
nodes
1/5
, Orofacial Anatomy II Final Exam Review
- Where do all of these nodes empty into? ans *Posterior Auricular Lymph
Nodes:Located posterior to each auricle & the external acoustic meatus, where the stern-
ocleidomastoid muscle inserts on the mastoid process
*Anterior Auricular Lymph Nodes:* Located immediately anterior to each tragus
*Superficial Parotid Lymph Nodes:* Superficial to each parotid salivary gland
All of these nodes empty into the *deep cervical nodes*
8. Which is bigger the thoracic duct or the right lymphatic duct? ans The
thoracic duct is much larger than the right lymphatic duct because it drains the lymph from
the entire lower half of the body for both the right & left sides
9. Where does the occipital nodes drain into specifically? ans Empty into the
infe- rior deep cervical nodes
