Answer 18

Cutaneous branch of the deep fibular nerve

Question 19

• Supplies structures of the anterior compartment of the leg
• Smaller terminal branch of the popliteal artery
• passes through an opening in the proximal portion of the interosseous membrane
• Vessels leaves the anterior compartment of the leg & becomes superifical & continues on the dorsum of the foot becoming the dorsal pedis artery

Answer 19

Anterior Tibial artery
