Flashcards in Clinical Relevant Lymphatics Deck (23):
1

What does the lymphatic system do

Removes excess fluid form the tissues of the body and returns it to the venous system
Carries fat from GI tract to the venous system
Produces immune cells in defence against infection and cancer

2

What is the important name change

Excess fluid left in tissue is tissue fluid by as soon as taken up by lymphatic system it is called lymph

3

What is the condition which can occur if the lymphatic drainage is not efficient

Elephantiasis

4

What are regional lymph nodes

Group of nodes which first receive lymph form any given structure

5

What do lymph nodes do

Screened for infectious agents and cancer cells by lymphocytes and macrophages
Swells if fights it

6

Where is lymph not produced in soft tissues

Brain

7

What are the two groups of the lymph nodes of the head and neck

Superficial and deep cervical nodes

8

Where does the superficial ring of the regional lymph nodes drain

Drain scalp, face, superficial upper neck

9

What are the superficial nodes

Occipital nodes
Mastoid nodes
Parotid nodes
Buccal nodes


Superficial cervical nodes
Sub mental nodes
Submandibular nodes

10

What are the deep lymph nodes

Deep cervical nodes
Retropharyngeal nodes
Su mental and submandibular nodes

11

What are the tonsils of the head and neck

Palatine tonsil
Palatine associated lymphoid tissue
Pharyngeal tonsil adenoid
Tubal tonsil

12

Where is the palatine tonsil

Oropharynx
Between 2 arches anterior arch caused by mucosa of palatal glossus extending form palate to side of the tongue
Then posterior arch - palatopharyngeus

13

Where is the pharyngeal tonsil adenoid found

Nasopharynx superior margin

14

Where are the tubal tonsils found

Nasopharynx
Surround auditory tube just under mucosa of nasopharynx

15

What is the waldeyer's ring of lymphoid tissue

Circumscribes the nasopharynx and oropharynx some tonsilar tissue in soft palate
Tonsils first line of defence against exogenous aggressors
Generation of B cells in germinal centres of tonsils

16

What drains specifically to the jugulo-digrastic node

Lymph from the palatine tonsil
If enlarged - tonsillitis

17

Where does all soft and hard tissue lymph of the mouth drain to

Sub mental node then submandibular then deep cervical

18

What is drained form the sun metal nodes

Lower anterior teeth
Alveolar bone
Gingiva
Middle of lower lip and chin
Tip of tongue

19

What is the lymphatic drainage of the anterior 2/3rs of the tongue

Middle drains - bilaterally to inferior deep cervical lymph nodes
Sides drains - unilaterally to submandibular nodes
Tip drains - bilaterally to sub mental nodes

20

What is the lymphatic drainage of theosteriro 1/3rd of the tongue

Bilaterally to superior deep cervical lymph nodes

21

What happens to infected lymph nodes

Swollen
Painful
Soft
Smooth
Not fixed
Improves with antibiotics

22

What are the features of cancerous lymph nodes

Swollen
Not painful
Hard
Irregular
Fixed
Don't improve

23

What is the lymphatic system

System of organs - bone marrow, spleen, thymus
Lymphatic vessels + lymph nodes and mucosa associated lymphoid tissue
