PART 1️⃣ | Anatomy Analysis, Lymphatic System.
🟢Superficial Inguinal Lymph Nodes
💥Location:
Situated in the subcutaneous tissue of the upper inner thigh, inferior to the inguinal ligament.
💥Structure: Comprised of about 10 nodes, often divided into superomedial, superolateral, and inferior groups.
💥Drainage Areas: These nodes receive lymph from the abdominal wall (below the umbilicus), buttocks, external ge***alia, a**l ca**l (below the pectinate line), lower va**na, and lower limbs.
💥Clinical Significance: They commonly swell in response to infections or malignancies in the areas they drain, such as skin infections in the legs or ge***al infections.
🟢Deep Inguinal Lymph Nodes
💥Location: Situated deep to the fascia lata, medial to the femoral vein, and deep to the femoral sheath.
💥Structure: Consists of generally 1–3 nodes, with the highest node (often found in the femoral ca**l) known as Cloquet’s (or Rosenmuller’s) node.
💥Drainage Areas: These receive lymph from the superficial inguinal nodes, as well as directly from the deep tissues of the lower limb, g***s p***s, and g***s cl****is.
💥Final Pathway: Deep inguinal nodes drain into the external iliac lymph nodes
