 I want to go over the muscles of the lower extremity with you. Specifically, I'm going to focus in on the muscles of the lower leg. Let's start from here. This is your tibia bone. So that would be your shin bone. That's your tibia. And we're going to start here and then go around the leg to the other side so that you can keep up and try to study these in order as you go around the leg. So if we're starting here at the tibia bone, this first one is obviously on the front. This is on the anterior side of the leg. So when you see this one, this one will be easy. This one is called tibialis anterior. Right next to the tibia on the front, tibialis anterior. As we come around, you see this next one right next to tibialis anterior. This one goes all the way to these tendons on the anterior side, top of the foot. This one is called extensor digitorum longus. This one is extensor digitorum longus because it literally extends the toes. The next muscle coming around then, next to extensor digitorum longus, is going to be on the side with the fibula bone. You see the malleolus here of the fibula, the lateral malleolus. This muscle then is named for that bone. So this one is called fibularis. There's another name for this muscle though called peronius. So you'll hear people will pull their peronius muscle. The next muscle coming around here is going to be the soleus. This is soleus muscle. And then on the very posterior side of the leg, you have your calf muscle. This one is gastronemius. It's spelled gastrocnemius, but it's pronounced gastronemius. You see that it has two heads to that muscle. Now all of this here that will be connecting these muscles to the heel bone here, this is our achilles tendon. The achilles tendon attaches to the calcaneus bone, the heel bone. So the other name for this is the calcaneus tendon, calcaneal tendon. This is the calcaneal tendon. If we come around to this side, we see again gastronemius and a piece of the soleus again. This muscle here next is going to be halusis. This one is halusis. And then we're back to the tibia bone again on the anterior side. Here's a chance to quiz yourself. This is again the tibia, and as I go around, you can name these out loud or you can take a chance to write them down. Again, here's the tibia. So name or write down the muscles as I touch them.
