THE SOLE OF THE FOOT 1. The plantar aponeurosis is attached to the calcaneal tuberosity and divides into five processes, one for each toe. Each process splits opposite the metatarsophalangeal joint into superficial and the deep stratum which the superficial stratum is attached to the skin of the transverse sulcus which separates the toes from the sole the deep stratum divides into two slips which flank the flexors tendons of the toes both neither Of course. No, the answer is C. 2. The muscles of the sole of the foot may be divided into four layers. The first layer consists of abductor digiti minimi muscle abductor hallucis muscle flexor digitorum brevis all of the above Hooray! No, D is correct. 3. The second layer of the muscles of the sole of the foot consists of the flexor digitorum accessorius (quadratus plantae) muscle, four lumbrical muscles, the tendon of flexor digitorum longus muscle and the tendon of the flexor hallucis longus muscle the adductor hallucis muscle Very good. No, A is the answer. The adductor hallucis muscle belongs to the third layer of the muscles of the sole of the foot. 4. The third layer of the muscles of the sole of the foot consists of the adductor hallucis muscle, flexor hallucis brevis muscle and flexor digiti minimi muscle the fourth interosseous muscle Right. No, A is the answer. The interossei muscles belong to the fourth layer. 5. The fourth layer of the muscles of the sole of the foot consists of the dorsal interossei muscles and the plantar interossei muscle the lumbrical muscles Correct. No, the answer is A. As it was stated before the lumbrical muscles belong to the second layer. 6. The interossei muscles of the foot are arranged relative to the third toe the second toe Yes. No, B is correct. 7. The lateral plantar nerve supplies all muscles of the first layer second layer fourth layer Bravo! Too bad, C is the answer. All the interossei muscles of the foot are supplied by the lateral plantar nerve. 8. Medial and the lateral plantar nerve as well as the medial and the lateral plantar artery are located on the sole of the foot between the first and the second layer the second and the third layer the third and the fourth layer Excellent! Wrong, the answer is A. 9. The plantar arch and the deep branch of the lateral plantar nerve are located on the sole of the foot between the second and third layer third and fourth layer fourth layer and the metatarsal bones Good. Wrong, B is correct. 10. In which layer of the muscles of the sole of the foot do you find the tendon of tibialis posterior muscle and the tendon of the peroneus longus muscle the second layer the third layer the fourth layer Marvelous! No, C is correct. 11. The medial plantar nerve is the largest of the two divisions of the tibial nerve. Its origin is under cover of the flexor retinaculum. From its origin it passes deep to the abductor hallucis and appears between this muscle and the flexor digitorum brevis adductor hallucis, the oblique head abductor digiti minimi Fine. No, A is the answer. 12. The skin of the great toe is supplied by the proper digital nerve of the great toe the first plantar digital nerve both of the above Very good. No, C is the answer. The proper digital nerve of the great toe supplies the medial aspect of the skin of the first toe while the first plantar digital nerve supplies the lateral aspect of it as well as the medial aspect of the second toe. 13. The muscular branches of the medial plantar nerve supply the abductor hallucis muscle the abductor hallucis, the flexor digitorum brevis muscle the above muscles and the flexor hallucis brevis muscle all of the above and the first lumbrical muscle Great! Too bad, the answer is D. 14. The lateral plantar nerve splits into two branches, the superficial and the deep branch. Which of these two branches supplies the second, third and the fourth lumbrical muscle? the deep branch the superficial branch Hooray! No, A is correct. 15. The skin on the lateral aspect of the fifth toe is supplied by the deep branch of the lateral plantar nerve superficial branch of the lateral plantar nerve medial plantar nerve Right. No. The correct answer is B. 16. The interossei muscles of the foot are supplied by the medial plantar nerve deep branch of the lateral plantar nerve superficial branch of the lateral plantar nerve Great! No, B is correct. 17. Distribution of the lateral plantar nerve can be compared with which of the nerves supplying the hand the radial nerve the median nerve the ulnar nerve Fine. Sorry, C is the answer. 18. The plantar arch extends from the base of the fifth metatarsal bone to the proximal part of the first intermetatarsal space base of the fifth metatarsal bone to the proximal part of the second intermetatarsal space Hooray! No, the correct answer is A. 19. The branches of the plantar arch are three perforating branches four plantar metatarsal arteries all of the above Of course. Sorry, you are wrong. C is correct. Three perforating branches ascend through the proximal ends of the second, third and fourth interosseus spaces and anastomose with the dorsal metatarsal arteries. Each plantar metatarsal artery divides into two plantar digital arteries which supply the sides of adjacent toes.
