• Quadriceps tendon

Q3. Which terminal branch of the tibial nerve supplies abductor digiti minimi?

• Medial plantar nerve
• Sural nerve
• Lateral plantar nerve
• Deep fibular nerve

Q4. Which artery is most directly associated with the neurovascular supply of the lateral plantar region containing this muscle?

• Descending genicular artery
• Anterior tibial recurrent artery
• Lateral plantar artery
• Dorsalis pedis artery only

Q5. How is abductor digiti minimi related to the plantar aponeurosis?

• It passes through the ankle extensor retinaculum
• It lies entirely on the dorsum
• It lies superficial to the skin
• It lies deep to the plantar aponeurosis

Q7. What is the relationship of abductor digiti minimi to flexor digitorum brevis in the superficial sole?

• It lies medial to abductor hallucis
• It lies lateral to flexor digitorum brevis
• It lies within flexor digitorum longus
• It lies dorsal to the metatarsals

Q8. Why can abductor digiti minimi contribute to lateral longitudinal arch support?

• It forms the plantar calcaneonavicular ligament
• It is the primary static ligament of the medial arch
• Its longitudinal course along the lateral sole can assist dynamic support
• It directly locks the ankle mortise

Q9. Which structure is near the distal attachment of abductor digiti minimi?

• Head of the talus

• Fifth metatarsophalangeal joint
• Medial malleolus

Q10. What distinguishes abductor digiti minimi from flexor digiti minimi brevis?

• It originates from the tibial shaft
• It is a first-layer muscle arising proximally from the calcaneal region
• It is a dorsal muscle supplied by the deep fibular nerve
• It inserts on the great toe
