 So next, since we're already in the arms, then I identify the biceps and the triceps. And the triceps are visible just on the surface. So this is one of the head groups of the triceps. The biceps, however, are underneath this muscle here. So this is going to require cutting across the midline of this muscle and reflecting the muscle back. So again, just for emphasis, the tricep is already revealed. And the other head groups of that tricep are visible here. And so for the biceps, we are going to need to remove this top muscle. So in order to do that, we're going to create some incisions. And it's actually to get a better angle of this. I'm going to rotate the cat over to the dorsal side. And make the incision where I see these two muscle groups. So I can see that there's this muscle group here. And then the triceps kind of go underneath that. So what I want to do is just separate, go along this line, and create an opening for that. So that's just enough of an opening. So that now what I can do is take my probe and actually find where is this muscle on the underneath side. So I've been able to find kind of the access point in between the triceps and the muscle that lays over top. That we're going to need to get around. So you can see how the probe has gone through to the other side. And that lets me know where the boundary is between this muscle here and the muscle that we're trying to bisect. So I'll kind of use that hole as my marker. And now again cutting away from my body just follow that line. And so now I've made an exit point. So now I can insert the probe here, reach over, and it should come out over on the other side and indeed it will. So I'm actually just going to leave that probe inserted there to really help show where this muscle separation is. So you can see I've made the cut. And so now what I'm going to do, I'm going to again just leave the probe there because it's serving as an excellent marker. And I'm just going to make a cut to bisect this muscle. So I already know what the underneath part is because that's where my probe is running. And I can just make my cut all the way over to this side there. So I've been able to bisect that muscle and I'll clean it up just a little bit with the connective tissue. Alright so we have bisected this muscle and if we reflect it back then we can see now the biceps are revealed. Alright so the biceps are a deep muscle so you'll have to get to them by cutting the muscle that is superficial to them. In order to, like I said, you can see the triceps here. And so this is a sufficient reveal on this muscle. Alternatively, to see the entire group this very, very thin superficial muscle can be removed. But I'm not going to because there's enough of a reveal on the tricep there. So we have the triceps, the triceps brachii, the biceps brachii. And then we have here our pectoralis major pectoralis minor.
