Unveiling the Hand's Anatomy in Virtual Reality

So if you cut too deep right away, you'll see that you'll be cutting through some of those structures on this next layer down, this little bump right there, which you won't always see, looks like absolutely nothing.

But if we go another layer down over here, you'll realize that that little bump is, in fact, a branch coming off of the radial artery. So we don't want to go through there, which is what we will do if you cut too deep.

The last thing I want to point out is this structure right here. This is the palmar aponeurosis. It's a very superficial structure. The next layer down, this palmar aponeurosis right here, has been cut. And in so doing, you can see this next layer down here. This is the flexor retinaculum.

And when we look at the hand a little bit further distal, you will see some of these other branches of nerves and arteries, and they're passing deep to this palmar aponeurosis.
