Answer 1

• Right side of head and neck
• Right upper limb
• Upper right quadrant

Question 2

• Lower trunk
• Lower limbs (both)

Question 4

Where does lymph from the left drainage area flow and where does it empty?

Answer 4

Left side -
Flows into: Thoracic duct, transports lymph up to left lymphatic duct
Empties into: left subclavian vein

Question 5

What does the horizontal superficial ring of nodes surround?

Answer 5

It surrounds the transition area between the head and neck.

Question 6

What does the horizontal deep ring of nodes surround?

Answer 6

It surrounds the visceral structures of the neck.

Question 7

To which lymph nodes does the Left Deep Cervical chain drain?

Answer 7

It drains into the thoracic duct, which drains into the junction of the subclavian and internal jugular vein.

Question 8

To which lymph nodes does the Right Deep Cervical chain drain into?

Answer 8

It drains into the Common Right Lymphatic duct, which then drains into the junction of the subclavian and internal jugular vein.

Question 9

Which lymph nodes make up the Superficial horizontal ring?

Answer 9

Submental (4)
Submandibular (7)
Superficial Parotid (4)
Deep Parotid (4)
Retroauricular (2)
Occipital (1)

Question 10

Which lymph nodes make up the Deep horizontal ring?

Answer 10

Retropharyngeal (3)

The below lymph nodes are for the nose, ear, pharnyx, larynx, and trachea.  (I don't believe that we have to remember them.)
Paratracheal (2)
Pre-tracheal 
Pre-laryngeal

Question 11

To which lymph node do the lower lip and chin drain?

Answer 11

Submental lymph node

Question 12

To which lymph node do the upper lip and cheek drain?

Answer 12

Submandibular lymph node

Question 13

To which lymph node do the eyelids, temples, prominence of cheek, and auricle of the ear drain?

Answer 13

Superficial parotid lymph node

Question 14

To which lymph nodes does the scalp drain?

Answer 14

Retroauricular and occipital.

Question 15

To which lymph node does the tip of the tongue drain?

Answer 15

Submental lymph node

Question 16

To which lymph node does the lateral part of the anterior 2/3rd of the tongue drain?

Answer 16

Submandibular lymph node

Question 17

To which lymph node does the medial part of the anterior 2/3rd of the tongue drain?

Answer 17

It drains directly into the deep cervical nodes (Common right lymphatic and thoracic ducts).

Question 18

To which lymph node does lymph from the Posterior 1/3rd of the tongue drain?

Answer 18

It drains into the retropharyngeal lymph node. The retropharyngeal lymph node is part of the deep horizontal ring.

For this lecture, this is one of only two instances that something drains into the Retropharyneal lymph node (Palatal gingiva also drains into it).

Question 19

To which lymph node does maxillary teeth drain into?

Answer 19

Submandibular lymph node

Question 20

To which lymph node does mandibular teeth drain?

Answer 20

Deep cervical nodes (common right lymphatic duct and thoracic duct)

Question 21

To which lymph node does lymph from the anterior floor of the mouth drain?

Answer 21

Submental lymph node

Question 22

To which lymph node do the mandibular lingual gingiva and floor of mouth drain?

Answer 22

The submandibular node and the deep cervical nodes (right common lymphatic and thoracic duct)

Question 23

To which lymph node do the vestibular gingiva of the maxilla and mandibular drain?

Answer 23

Submandibular lymph node

Question 24

To which lymph nodes does lymph from the palatal gingiva drain?

Answer 24

Submandibular and Retropharyngeal lymph nodes

(This is one of only two regions that drains into a deep horizontal ring node [retropharyngeal]. The other is the Posterior 1/3rd of the tongue).

Question 25

Question 27

Which regions/structures drain into the Superficial Parotid lymph node?

Answer 27
