1

where do the lymphatic ducts drain into

right and left subclavian veins

2

what are the names of the two main lymphatic ducts

right lymphatic duct and thoracic duct

3

what ducts are the main draining vessels of the head and neck

jugular trunks

4

where are the lymph nodes

between the lymph capillaries and the lymph vessels

5

what lymph node may be enlarged in tonsilitis

jugulodigastric (neck, posterior belly of digastric crossing the IVJ

6

what do the upper deep cervical lymph nodes receive lymph from

superficial lymph node groups

tongue and tonsils

feeds to lower deep nodes and jugular trunk

7

where is juguloomohyoid node

part of lower deep cervical nodes

drains anterior 2/3rds of tongue

8

where are the lower deep cervical nodes

back of neck and scalp

9

what do the lower deep cervical nodes drain

superficial pectoral region
tongue
superficial deep cervical glands

feeds to jugular trunk

10

what is the drainage of the anterior 2/3rd of tongue

juguloomohyoid node

11

what node is just below the external auditory meatus

jugulodigastric node

12

what is the general lymph drainage of the face

most lymph goes from superficial nodes in the face into deep cervical nodes in the neck (superior then inferior)

13

what do the submental nodes drain (then to submandibular)

floor of the mouth beneath the tongue tip, incisor and gum, central lower lip, chin skin

14

what do the buccal nodes drain (then to submandibular nodes)

lower eyelid, cheek, buccinator, facial vein

15

what do the submandibular nodes drain (then to deep cervical nodes)

nose, cheek, lower lip, frontal/max/ethmoidal sinuses
upper/lower teeth, ant 2/3 of tongue

16

What do the parotid nodes drain (to superior deep cervical)

eyelid, nose, external acoustic meatus, tympanic cavity
parts of nasal pharynx

17

what do the mastoid aka post auricular nodes drain (superior deep cervical)

strip of scalp above auricle, posterior external auditory meatus

18

what do the occipital nodes drain (to deep cervical)

back of the scalp

19

what do the superficial cervical nodes drain

skin over jaw angle, parotid apex and lobule of ear

20

what do the retropharyngeal nodes drain

pharynx, auditory tube, soft palate, hard palate, nose

21

what do the paratracheal nodes drain

neighbouring structures
thyroid

22

where are the deep lymph nodes

surround the larynx, trachea and pharynx, oesophagus

23

what do the retropharyngeal nodes drain

nasal cavities/nasal pharynx, auditory tube

24

what is the first node in drainage of the nasopharynx

node of rouviere

25

what node enlargement is associated with poor prognosis in thyroid cancer

delphian node
aka pretracheal node on the cricothryoid membrane

26

what is the drainage of the thyroid

pretracheal/ paratracheal/ prelaryngeal to deep cervical nodes

27

what is the lymph drainage from the lips

submandibular lymph nodes
submental lymph nodes

28

what is the lymph drainage of the back of the tongue

superior deep cervical lymph nodes including jugulodigastric

29

what is the lymph drainage of the side of the tongue

inferior deep cervical nodes + juguloomohyoid and submandibular nodes

30

what is the lymph drainage of the tip of the tongue

submental

31

why might tongue lesions present on both sides of the neck

significant drainage on both sides and crosses over the tongue

32

what tumour makes up 90% of all oral cancers

squamous cell carcinoma

floor of mouth and tongue

33

what is the prognosis of squamous cell carcinomas in the tongue strongly dependant on

whether there are detectable metastases in cervical lymph nodes

contralateral lymph node metastases suggests poor prognosis

34

what is virchow's node

enlarged left supraclavicular node

abdominal/stomach tumour

35

what tonsils make up waldeyer's ring

pharyngeal tonsil
palatine tonsil
lingual tonsil

36

what is waldeyers ring

an interrupted circle of protective lymph tissue

upper ends of alimentary respiratory tracts

37

what are tonsils

lymphoid nodules invaginated epithelium which increases contact with digested organisms

facilitates immunity

38

where is the pharyngeal tonsil

back of nasopharynx

39

where is the palatine tonsil

back of oropharynx

40

where is the lingual tonsil

bottom of tongue

41

what is the N in TMN staging based on

lymph node sidedness , number and size

42

what is the sentinel node

hypothetical first lymph node draining a cancer

43

how can you ID the sentinel node

imaging
test by histopathology

44

what is lymphoscintigraphy

senetinel lymph node mapping

45

what is another possible means of tumour spread in the head and neck

perineural

trigeminal, facial and hypoglossal nerves are important routes

46

what fossa is an important cross roads for perineural and perivascular spread

pterygopalatine fossa

communicates with the orbit, oral cavity, nasal cavity and middle cranial fossa

47

where is lymph drainage of the brain

lymphatics run alongside dural sinuses and goes to deep cervical nodes
