The radial artery terminates at the level of the wrist by dividing into a superficial palmar branch and a deep palmar branch.
Lateraly and and just distally to the pisiform bone the ulnar artery is also diving into a superficial palmar branch and a deep palmar branch.
Before giving their superficial and deep palmar branches, the ulnar and radial arteries gives off a palmar carpal branch which will anastomose to form the palmar carpal arch. This arch is also joined by the posterior interosseous artery.
The superficial palmar arch is realized mostly by the superficial palmar branch of the ulnar artery which is anastomosing with the superficial palmar branch of the radial artery.
We have the following branches from the superficial palmar arterial arch.
Three common palmar digital arteries for the second, third and fourth intermetacarpal spaces. Each of the common palmar digital arteries divides into proper palmar digital arteries which supply their
adjacent sides.
The superficial palmar arch is also giving One proper digital artery that runs along the medial side of
the little finger which it supplies.
The deep palmar arch is formed mainly from the deep palmar branch of radial artery, with the ulnar artery contributing via its deep palmar branch, by an anastomosis.
The deep palmar branch of radial artery winds round the wrist thus arriving at the base of the first intermetacarpal space on the back of the hand. Here it pierces the base of the first intermetacarpal space finaly arriving in the palm where firstly passes between the two heads of adductor policis.
The deep palmar branch of ulnar artery descends between the pisiform and hook of hamate and then passes undercover of opponens digiti minimi , finaly arriving at the base of the 4th intermetacarpal space where it unites with the deep palmar branch of radial artery thus the deep palmar arterial arch being formed.
The deep palmar arch gives of the following branches.
Princeps policis artery which splits into proper digital arteries of thumb.
Radialis indicis artery for the lateral side of index.
And three palmar metacarpal arteries which terminates into the three common palmar digital arteries.
At the base of the intermetacarpal spaces the deep palmar arch gives of perforating branches.

You are so underrated. Youre easily one of thr best and most effective teachers of anatomy. You have such a natural talent of simplifying complicated diagrams so they're understandable and easy to memorise. Thank you very much for making these videos, you've helped me more than any anatomy teacher has.
Wait a second - you can write using both left and right hand? Damn
This is, by far, the most effective video I've found for vessels of superior extremity. Thank you, sir.
Jesus loves you .
Jesus bless you

oh my god...with both hand?i cant believe my eyes you are definitely a gift
Anterior interosseous branch joins the ulnar and radial branches to form the palmar carpal branch and not posterior interosseous. I hope you double check that, thanks for the amazing video.
No he's very right.The anterior interosseous artery wich is a branch of the common interosseous artery running on the front of the forearm,at upper part of the pronator quadratus it pierces the membrane and descends on the dorsal aspect of the hand where it's joined by the posterior interosseous artery to anastomose with dorsal carpal arch.He's right.
@@jakomjaduong6288 in the video he accidentally said that the "posterior" interosseus aretery anastomoses with "palmar" carpal arch. That's the issue.
Yesss. I was confused for a moment.
@@theunknownexplorer1944 what he actually meant is the median artery, which is a small branch of the anterior interosseous artery.
thank you, this is the most simplified video for arches
Thankfully you're the best teacher
Thanks. Because of your instructive videos, I could make an excellent mark in anatomy. Thanks enough
I'm very pleased to hear that! Thank you too 🙏
Thank you so so much I really appreciate your working ❤️❤️ you helped me so much ❤️
honestly, I haven't seen this much amazing anat video.
please make more
I saw you last updated it in March.

@@AnatomyKnowledge yes i saw it in the suggestions after i commented. thank u very much!! : )
Very superb explanation sir , SO so much ty sir
Can you please let me know if you have uploaded videos on nerves too...?
Yes! You cand find all the nerves for the upper limb on this channel!
@@AnatomyKnowledge Thank you so much for replying and yeah..your videos are really helping me out with my studies . I was all depressed and sad because I couldn't understand things.
Keep going👏🏻
The number of phalanges of the 5th finger is 3 not 4
Hope you check it !
Can u please tell us the book you are using? Thanks

can zoom in a bit? cannot tell the names
Bro casually writes with both hands wow
If you add subtitle till be more useful sir
Thank you🙂🙂

You see... VENTRAL ... 5th finger???phalanx
Did you mean to say the superficial palmar arch gives a proper digital branch for the LATERAL side of digiti minimi? In the video you said it runs medially, but you drew it on the left side of the pinky in the ventral view so wouldn’t that be lateral?
