Inguinal nodes cluster in the groin, draining the lower limb, perineum, and lower abdominal wall.
The inguinal lymph nodes are superficial and deep lymphatic nodes located in the inguinal (groin) region. They are responsible for filtering lymph from the lower limb, external genitalia, perineum, and lower abdominal wall. These nodes are important in clinical examination due to their accessibility and are frequently involved in infections, malignancies, and immune responses.
The inguinal lymph nodes are divided into two main groups:
Inguinal nodes lie in the upper thigh and groin region, inferior to the inguinal ligament and adjacent to the femoral triangle.
Group | Anatomical Location |
---|---|
Superficial (horizontal) | Parallel to the inguinal ligament, just beneath the skin |
Superficial (vertical) | Alongside the great saphenous vein in the upper thigh |
Deep | Medial to the femoral vein, within the femoral triangle |
