Lymphatics of the leg

Question 1

What are the two groups of lymphs in the leg

Answer 1

Superficial lymph nodes

Deep lymph nodes

Question 2

Describe the course of the superficial lymph nodes

Answer 2

Lateral vessels- Arise from lateral surface of foot, follow small saphenous vein, enter popliteal nodes

Medial vessels- originate from doral foot, travel up anterior and posterior leg, then pass with great saphenous vein. Terminates in thigh draining sub inguinal nodes

Question 3

What are the inguinal nodes?

Answer 3

Found in the upper aspect of the femoral triangle, numbered 1-20. Subdivided into 3 groups: superficil subinguinal, superfifical sub inguinal, deep sub inguinal

Question 4

Describe the superfifical inguinal nodes

Answer 4

These form a line directly below the inguinal ligament and receive lymph from the penis, scrotum, perineum, buttock and abdominal wall

Question 5

Describe the superificial sub inguinal nodes

Answer 5

Located on each side of the proximal section of the great saphenous vein. Receive afferent input primarily from the superfifical lymphatic vessels of the lower leg

Question 6

Describe the deep sub-inguinal nodes

Answer 6

Most commonly found on the medial aspect of the femoral vein

Question 7

Describe the popliteal nodes?

Answer 7

Most commonly found in fat reserves in the popliteal fossa. Recieve lymph from the lateral superficial vessels

Efferent vesses of the popliteal nodes pass almost enitrely alongside the femoral vessels to empty into the deep inguinal nodes.
