Inguinal lymph node

Lymphatics from glans penis, prostatic urethra, spongy urethra and superficial inguinal nodes drains into deep inguinal lymph nodes.

Principal nodes involved in the lymphatic drainage of cervix are the obturator, common iliac, external iliac, internal iliac and the nodes of parametrium. Lymphatics from cervix do not drain into the deep iuguinal lymph nodes.

A. i.e. Glans penis

A. i.e. Glands of cloquet; C. i.e. Deep injuinal lymph nodes 

–   Glans penis & clitoris drain in deep inguinal lymph nodes of Cloquet or Rosenmuller

Superficial inguinal lymph nodes drain anterior abdominal wall below umbilicus, perineum, anal canal (gluteal region) but not clitoris & toes and fingers.

Superficial Inguinal Lymph Nodes

• The horizontal group
• The medial members of the group receive superficial lymph vessels from the anterior abdominal wall below the level of the umbilicus and from the perineum. The lymph vessels from the urethra, the external genitalia of both sexes (but not the testes), and the lower half of the anal canal are drained by this route.
• The lateral members of the group receive superficial lymph vessels from the back below the level of the iliac crests.
• The vertical group lies along the terminal part of the great saphenous vein and receives most of the superficial lymph vessels of the lower limb.

The efferent lymph vessels from the superficial inguinal nodes pass through the saphenous opening in the deep fascia and join the deep inguinal nodes.

Deep Inguinal Lymph Nodes

The deep nodes are located beneath the deep fascia and lie along the medial side of the femoral vein; the efferent vessels from these nodes enter the abdomen by passing through the femoral canal to lymph nodes along the external iliac artery Lymphatic Drainage of the Penis

From most of the penis, lymph drains into the superficial inguinal lymph nodes.

Vessels from the glans penis drain into the deep inguinal lymph nodes.

Vessels from the glans penis drain into the deep inguinal lymph nodes (gland of Cloquet)

From rest of the penis, lymph drains into the superficial inguinal lymph nodes.

Ans. is ‘c’ i.e., Superficial inguinal nodes

Lymphatics of Vulva drain primarily into superficial inguinal lymph nodes and subsequently to deep inguinal and external iliac ndes. Lymphatics of Clitoris primarily drain into deep inguinal nodes.
