1

What are the types of inguinal lymph nodes

Sub-ingual
Superficial

2

How are the sub-ingual lymph nodes divided

Deep
Superficial

3

Location of sub-ingual lymph nodes

Below level of termination of great sephanous vein

4

Location of superficial lymph nodes

Above level of termination of great sephanous vein

5

Supply of superficial lymph nodes

Receive lymph from:
Penis
Scrotum
Perineum
Buttock
Abdominal wall

6

Location of superficial sub-ingual nodes

Both sides of great sephanous vein

7

Supply of superficial sub-ingual nodes

Receive lymph from:
Superficial lymphatic vessels of lower leg
- medial superficial lymphatic vessels associated with GSV
- lateral superficial lymphatic vessels associated with SSV

8

Location of deep sub-ingual nodes

Medial side of femoral vein

9

Supply of deep sub-ingual nodes

Receive lymph from:
Deep lymphatic trunks of thigh
- anterior tibial trunk associated with anterior tibial artery
- posterior tibial trunk associated with posterior tibial artery
- perineal trunk associated with perineal artery

10

Location to popliteal lymph nodes

Fat reserves of popliteal fossa

11

Supply of popliteal lymph nodes

Receive lymph from:
Lateral superficial lymph vessels

12

Course of efferent vessels of popliteal lymph nodes

Most pass alongside femoral vessels and empty into deep sub-ingual nodes

Some pass alongside GSV and empty into sub-ingual nodes

13

What is lymphadenopathy

Abnormality in size, number or consistency of lymphatic nodes

14

Usual cause of lymphadenopathy

Infection
Malignancy
Autoimmune condition

15

What should be examined in suspected lower limb lymphadenopathy

Lower limb
Penis
Scrotum
Buttocks
Abdominal wall

16

Why do the testicles rarely cause inguinal lymph node enlargement

They drain directly into paraaortic nodes

17

Location of inguinal lymph nodes
