Hi guys and gals! I'm just an artist, trying to properly model a human hand. Tell me please what is this what is this bulge on the wrist? It's head of ulna, extension of radius bone, some bone from wrist, or just a ganglion cyst?
Hi dear friend, it's not any other but styloid process of ulna, your picture represents so called "pianist hand" or rheumatoid wrist. Seems this is an answer to your question, good day to you!
