Which structure forms the lateral boundary of Hesselbach's triangle?

• A Linea semilunaris
• B Inferior epigastric vessels ✓
• C Conjoint tendon
• D Lacunar ligament

Explanation

Hesselbach's triangle is bounded medially by the lateral border of the rectus abdominis, superolaterally by the inferior epigastric vessels, and inferiorly by the inguinal ligament. A direct hernia passes through this triangle medial to the inferior epigastric vessels, while an indirect hernia enters the canal lateral to them through the deep ring. The linea semilunaris marks the lateral edge of the rectus sheath and plays no role here.
