 So now we shall continue and show more of these structures as well as the dorsum of foot in the next cadaver. This is another cadaver, this cadaver is supine and this is the right leg. And we will continue with the demonstration of the anterior compartment of the leg. This is the middle surface of the tibia, this is the anterior part of the tibia. And covering this was the drool fascia and this fascia that you see here is remnant of the drool fascia and this is the anterior intermuscular septum which is going and attaching to the anterior border of the fibula. So, between the anterior intermuscular septum and the anterior border of the tibia, this is the anterior compartment of the leg. So, this strong powerful muscle and the tendon that we see here, this is the tibialis anterior. Just we are going from medial to lateral. Then the next one that we see here, this is extensor halosus longus. The next tendon that we see, this is the composite tendon of the extensor digitoral longus to the lateral four digits. And finally, the lateral most that we see here, this is the fibularis tertius. So, these are the four tendons which are crossing the ankle joint under the extensor red neck. Tibialis anterior paralysis can lead to foot drop. That brings me to the important nerve. Running between the tibialis anterior as I mentioned in the previous dissection and the extensor halosus longus is this nerve here. This is the deep fibular nerve which is another terminal division of the common fibular nerve. It comes from the lateral to the anterior compartment and it supplies all the muscles of the anterior compartment. And then it continues down between the tibialis anterior and the extensor halosus longus. When it reaches the ankle joint, it goes under the extensor halosus longus and it continues further down. And we can see that going under the extensor halosus longus, this nerve. And it goes under the extensor red neck column and it comes to the foot. Doorsome of the foot, it supplies these muscles that we can see here. Part of it we can see here. This is the extensor halosus brevis and the lateral four slips are the extensor digitoral brevis. And it supplies these deep muscles on the dorsum of the foot. And after that the deep fibular nerve continues and it becomes cutaneous and supplies this interdigital cleft only. So, this is the only portion of the skin of the dorsum of the foot which is supplied by the deep fibular. The rest of the dorsum of the foot skin is supplied by the superficial fibular which I mentioned earlier. Now, let us take a look at the artery accompanying the deep fibular nerve. And this is the anterior artery with its accompanying venae cometantes. And we can see the venae cometantes on either side. This also runs between the tibialis anterior and the extensor halosus longus. And as it comes lower down, it goes under the extensor halosus longus. And it goes under the extensor red neck column as we can see here. And here after it crosses, it becomes known as a dorsalis pedis. So, we can see both these arteries and the nerve very clearly here. This is the place where the deep fibular nerve can get entrapped under the extensor red neck column which has been removed and it can produce what is known as the ski boot syndrome which will lead to weakness of the extensor halosus bravis and the extensor digital bravis and also numbness tingling and peristusia in the first interdigital cleft. So, this is about the distribution of the anterior tibial artery and the deep fibular nerve and the muscles of the anterior compartment. So, thank you very much for watching.
