More amazing than WTF. The ulnar artery, and tendons of the hand.

brenzdude · 2012-11-05T03:45:03+00:00

That is an extremely clean and great dissection. Amazing. Reminds me of the Body Worlds exhibit. I definitely had to construct my own palmar arch to get full credit last year in gross anatomy lab because my cadaver, uh...wasn't born with one.

thebigguru · 2012-11-05T01:19:39+00:00

Man I want chicken now...

evilcow320 · 2012-11-05T02:20:20+00:00

This is awesome I wanna see one of the whole body.

ilovehpb · 2012-11-05T00:54:03+00:00

Somehow, I don't understand how this NSFL. It's your body. I think it's weird how people find it weird to see what is just under our skin.

subtype · 2012-11-05T03:46:40+00:00

Dunno if it's just me, but the muscle at the base of the thumb looks delicious; kinda like a chicken drumstick.

fingersandtoes · 2012-11-05T03:34:55+00:00

I agree that this is definitely not NSFL! It's our bodies, and they are just amazing.

I don't think it's particularly accurate to label this as "ulnar artery" though, just saying. The ulnar artery is exactly where you'd expect it be-- mostly located in the forearm running along the ulna. This is the superficial palmar arch and the digital arteries, more so.

SentWest · 2012-11-05T01:44:38+00:00

TIL why the chick on the program about being addicted to heroin I was watching the other day had track marks in her palm. She apparently blew out everything else, and I was wondering what the hell she was going for on that side of the hand.

TripelNova · 2012-11-05T04:11:36+00:00

Now just imagine sticking a fork in there and giving it a spaghetti twist.

BondGirl20 · 2012-11-05T03:09:33+00:00

how is human anatomy NSFL?

We look like chicken

AntisocialBehavior · 2012-11-05T03:54:48+00:00

You can see a branch of the radial artery too making the superficial palmar arch artery! There is so much good anatomy to be learned from this dissection (which is amazing work)

fapping_bum · 2012-11-05T00:34:53+00:00

I don't think this is wtf and it definitely doesn't need a NSFL tag.

Bob_Saget_Enthusiast · 2012-11-05T03:49:14+00:00

So if it's amazing and not WTF, then why did you post it here?

bigglesxyz · 2012-11-05T05:41:37+00:00

I know this sounds really like psychotic, but I always wanted to do this to a hand when I was younger. Just like cut open an arm and just pull on stuff and see how it works.

heyopickle · 2012-11-05T05:49:17+00:00

Tastes like chicken

ayman85 · 2012-11-05T06:36:48+00:00

I work in an orthopedic surgical operating room and we had a patient come in who was attacked with a machete. He put his hands up to try and block the attack, and ended up getting his hands pretty badly cut up. While we were performing the surgery, the surgeon would pull on the tendons and we could see the fingers move with every pull. One of the coolest/disturbing things I have ever seen.

The human hand is amazing. I had surgery on mine two years ago which I decided to watch. When they pulled back my skin I was actually in awe of how complex it is.

kinsey3 · 2012-11-05T07:07:09+00:00

demain_jeparterai · 2012-11-05T07:12:19+00:00

In case any of you are interested in the other structures and don't feel like looking it up...

The thumb muscles you see are called the "thenar" muscles. Although it's difficult to discern, there are three of them. Abductor pollicis brevis, Flexor pollicis brevis, and Opponens pollicis. These muscles are innervated by the median recurrent nerve.
The muscles on the pinky side are called the "hypothenar" muscles. There are also three of these. Abductor digiti minimi, Flexor digiti minimi, and Opponens digiti minimi. These muscles are innervated by the ulnar nerve.
As noted, the red arching structure comes from the ulnar artery and is called the Superficial Palmar Arch. It is actually an anastomoses (or fusion, I suppose) of ulnar artery and radial artery, with primary contribution from ulnar artery. You can't tell in this picture, but there is another arch deep to this one called the Deep Palmar Arch, which is primarily radial artery. The red arteries that are branching off the superficial arch are officially called Common Palmar Digital Arteries. They branch further into Proper Palmer Digital Arteries.
The white tendons you see stretching out to each of the fingers are the tendons of Flexor Digitorum Superficialis. This is one of the muscles that runs in your Carpel Tunnel (it is actually a tunnel). The other muscles are Flexor Digitorum Profundus and Flexor Pollicis Longus (and Median Nerve)

The hand is really cool, I hope you guys find this information interesting!

ddime · 2012-11-05T07:24:19+00:00

I learned the functions of the Ulnar the hard way :( http://i.imgur.com/ZksfZ.png That was a few days after surgery to repair the nerve/artery (which apparently involved inserting a piece of sponge/conduit to bridge the nerve back together. I had apparently cut/mangled a solid chunk).I could barely unclaw my fingers then. Now, a few years later, the inner side of my hand always feels slightly asleep, with that super burning tingly feeling if touched, I also cannot cross any of my fingers.

speeder111 · 2012-11-05T07:26:04+00:00

I once went to a lab and got to handle some detached body parts. There was a hand like this, and it was one of my favorite pieces. You could actually still pull the tendons to make the fingers react! Best field trip ever, once you got used to the smell.
