And it also then serves as a instrument of sensation because it moves our head and our eyes around so that we can scan the environment. It's got internal sensors in it, which allow us to detect the carbon dioxide levels in our blood. It's got lots of lymph nodes in it, which are important in fighting infection. It's got the larynx, which does this amazing thing called speech and song.

Those are some of the multifunctions of the neck.

Well, this is one of the very interesting things about the neck and really one of the cruel things about the neck too is that we have at least two different pipes that are going down there. One is the windpipe and the other is the esophagus, that is the food pathway.

the cruel thing about these two pipes is that they cross and consequently sometimes in rare occasions the food can go down the wrong tube and it start head toward the lungs and that's a bad news and it will uh result in us choking so there's an extreme vulnerability associated with this crisscross of the tubes that is the windpipe and the esophagus the food tube the

There's at least one other set of cords that are really important, and that's the spinal cord. So the spinal cord goes up through the spine between the backbone and the brain, and any damage to that can very quickly result in death.

That's a really good question. Yes, our neck is one of the most complicated joint systems in the whole body. So we have seven bones there in our, you know, backbones, vertebrae in our neck, but they articulate it about 37 different places. So there's very complex joints in there which allow us to rotate quite a bit.

It's true that there are some important arteries that run up in there, but they tend to be housed in pretty big spaces, and also they are relatively stretchy. So even though you turn your head to the left and right, these critical vessels don't get stretched all that much.
