Intermediate Posterior Tibial Artery Quiz

Q1. At approximately what level does the posterior tibial artery begin?

• Head of the talus
• Inguinal ligament
• Adductor hiatus
• Lower border of popliteus

Q2. Which fascial structure separates the deep posterior compartment containing the artery from the superficial posterior compartment?

• Iliotibial tract
• Plantar aponeurosis
• Transverse intermuscular septum
• Interosseous membrane alone

Q3. Which muscle lies anterior to much of the posterior tibial artery in the leg?

• Tibialis posterior
• Rectus femoris
• Fibularis longus
• Gastrocnemius

Q4. Which muscles are major deep posterior compartment structures supplied by branches of the posterior tibial artery?

• Sartorius, gracilis, and rectus femoris
• Tibialis posterior, flexor digitorum longus, and flexor hallucis longus
• Tibialis anterior, extensor hallucis longus, and extensor digitorum longus
• Gluteus medius, minimus, and maximus

Q5. Which branch contributes to the arterial network around the medial ankle?

• Superior gluteal branches
• Dorsal metacarpal branches
• Lateral circumflex femoral branches
• Medial malleolar branches

Q6. Which branches of the posterior tibial artery supply the heel?

• External pudendal branches
• Calcaneal branches
• Perforating femoral branches
• Genicular branches

Q7. What is the usual relationship of the posterior tibial artery to the tibial nerve behind the medial malleolus?

• The nerve does not enter this region
• The artery lies inside the tibial nerve
• The artery lies anterior to the tibial nerve
• The artery is always superficial to the flexor retinaculum

Q8. Which tendon lies immediately anterior to the posterior tibial artery in the classic tarsal tunnel sequence?

• Achilles tendon
