Lymphatics of Pelvic Limb

Question 1

Popliteal Lymph Node

Answer 1

• constant
• palpable

Location: popliteal fossa (near biceps femoris m. and semitendinosus m.)

Afferent lymph vessels
-distal parts of the pelvic limb (distal to the limb node)

Efferent lymph vessels

• medial iliac lymph node
• femoral lymph node (if present)

Question 2

Superficial inguinal lymph node

Answer 2

• constant
• palpable

Location:
Female -deep side of inguinal mammary glands
Male -along dorsolateral border of penis

Afferent lymph vessels
Female = abdominal mammary glands, inguinal mammary glands
Male = penis, prepuce, scrotum

Efferent lymph vessels
-medial iliac lymph node

Question 3

Iliofemoral or deep inguinal lymph node

Answer 3

-inconstant

Location: dorsal to origin of deep femoral artery

Afferent lymph vessels

• Efferent lymph vessel from:
  
  • superficial inguinal ln.
  • popliteal ln.
  • femoral ln.

Efferent lymph vessel
-medial iliac lymph node

Question 4

Femoral lymph node

Answer 4

-inconstant

Location: distal part of femoral triangle

Afferent lymph vessels

• popliteal lymph node = efferent lymph vessel
• skin of medial side of pelvic limb

Efferent lymph nodes

• medial iliac lymph node
• iliofemoral lymph node

Question 5

Medial iliac lymph node

Answer 5

• constant
• SINGLE TERMINAL LYMPH NODE of hind limb and pelvic viscera

Location: Between deep circumflex artery and external iliac artery

Afferent lymph vessels

• Efferent lymph vessels from:
  
  • superficial inguinal ln.
  • popliteal ln.
  • femoral ln.
  • iliofemoral ln.

Efferent lymph vessels
-lumbar trunks -> cysterna chily (CH)

Question 6

Constant lymph nodes

Answer 6

• popliteal ln. = palpable
• superficial inguinal ln. = palpable
• medial iliac ln.

Question 7

Inconstant lymph nodes

Answer 7

• iliofemoral or deep inguinal ln.

- femoral ln.

Question 8

Single terminal lymph node?

Answer 8

Medial iliac lymph node
