Detailed 3D anatomical illustration of the inguinal ligament and conjoint tendon (falx inguinalis) of the lower abdominal wall and groin region. Show the inguinal ligament stretching from the anterior superior iliac spine (ASIS) to the pubic tubercle, and the conjoint tendon formed by the fusion of the internal oblique and transversus abdominis aponeuroses inserting into the pubic crest and pectineal line. Include surrounding muscles: external oblique, internal oblique, transversus abdominis, and rectus abdominis. Show the inguinal canal, deep and superficial inguinal rings, lacunar ligament, and iliopubic tract. Label all key structures clearly. Use realistic 3D rendering with semi-transparent muscle layers to reveal deep structures, warm anatomical color scheme with muscles in red-pink, tendons/ligaments in white-cream, bones in ivory.
