THE ANTERIOR AND THE ATERAL COMPARTMENT OF THE LEG
1. The fascia crura covers the muscles of the leg. On the lateral side of the leg, it is continuous withthe anterior intermuscular septum the posterior intermuscular septum all of the above are correct Very good! No, the best answer is C.
2. The deep transverse fascia of the leg passes betweenthe superficial and the deep muscles on the back of the leg the superficial and the deep muscles on the back of the leg and the peroneal muscles Fine! No, the answer is A.
3. Within the anterior muscular compartment of the leg, you find which of the following muscles?the tibialis anterior muscle the extensor digitorum longus muscle the peroneus tertius muscle all of the above Marvelous! Partly, the best answer is D. The peroneus tertius muscle is a part of the extensor digitorum longus muscle and might be described as its fifth tendon. Another muscle which you find within the anterior muscular compartment of the leg is the extensor hallucis longus muscle.
4. The tibialis anterior muscle is attached tothe medial cuneiform and the adjoining parts of the base of the first metatarsal bone the lateral cuneiform bone and the adjoining parts of the base of the first metatarsal bone Very good. No, the answer is A.
5. The tibialis anterior muscledorsiflex the foot on the leg inverts the foot on the leg all of the above Fine! No, C is correct.
6. The extensor hallucis longus muscle attaches tothe dorsal aspect of the base of the first phalanx (proximal) of the great toe the dorsal aspect of the base of the distal phalanx of the great toe Marvelous! No, the correct answer is B.
7. Within the lateral group of the muscles of the leg arethe invertors of the foot the evertors of the foot Hooray! No, the correct answer is B.
8. The lateral group of muscles of the leg consists of the peroneus longus and the peroneus brevis muscle. They pass onto the foot behindthe lateral malleolus the medial malleolus Yes. No, A is correct.
9. The peroneus longus muscle is attached tothe lateral aspect of the base of the first metatarsal bone the medial cuneiform bone all of the above Certainly. No, they are both attached so C is the answer.
10. The peroneus brevis muscle is attached tothe tubercle on the base of the fifth metatarsal bone the lateral cuneiform bone Excellent! No, the answer is A.
11. The anterior tibial artery is a terminal branch of the popliteal artery. It arises from the main trunk at the lower border of the popliteus muscle and within the popliteal fossa. It enters the front of the legfirst between two heads of the tibialis posterior muscle and through the upper part of the interosseus membrane medial to the neck of the fibula all of the above are correct Exactly. No, C is the answer I need.
12. Within the anterior muscular compartment of the leg, the anterior tibial artery relations arein its upper two-thirds, this artery descends upon the interosseus membrane in the lower third, it descends upon the tibia and the ankle joint the deep peroneal nerve is on its lateral side all of the above are correct. You are right. Partly, but all are correct and D is the answer. The anterior tibial artery within its upper two-thirds is flanked by the muscles, namely the tibialis anterior and the extensor digitorum longus in its upper third and in its middle third between the tibialis anterior and the extensor hallucis longus. The lower third of the anterior tibial artery is covered by skin and fasciae, and the extensor retinacula.
13. The peroneal artery originates fromthe popliteal artery the posterior tibial artery the anterior tibial artery Marvelous! No, B is the answer. The peroneal artery originates from the posterior tibial artery about 2.5 cm below the lower border of the popliteus muscle and passes obliquely towards the fibula.
14. The peroneal artery descends downwards ina groove between the tibialis posterior and the flexor hallucis longus muscles within the tissue of the flexor hallucis longus muscle all of the above are correct Of course. Partly, but the correct answer is C.
15. The cutaneous branches of the common peroneal nerve arethe lateral cutaneous nerve of the calf the sural communicating branch both Exactly! No, the best answer is C.
16. Deep to the peroneus longus muscle, the common peroneal nerve divides into two branches (nerves)the deep peroneal (anterior tibial) nerve the superficial peroneal (musculocutaneous) nerve both Good answer. No, the answer is C.
17. The following muscles of the anterior compartment of the leg are supplied by the deep peroneal nervethe tibialis anterior muscle and the peroneus tertius the tibialis anterior muscle and the extensor hallucis longus all of the above muscles and the extensor digitorum longus muscle Very good. Too bad, C is correct.
18. The extensor digitorum brevis muscle is supplied bythe lateral terminal branch of the deep peroneal nerve the medial terminal branch of the deep peroneal nerve Hooray! No, A is correct.
19. The superficial peroneal nerve at the lower third of the calf and superficial to the fascia crura divides into two branches the medial and the lateral. The lateral branch divides into the dorsal digital branches which supply the contiguous sides ofthe second, third and fourth toe the third, fourth and fifth toe Very good. No, the answer is B.
