Hey,

I'm a bit confused about the styloid process of the ulna. I thought it was the bony bump that this guy points to in the video.

However, one of the comments said that that is the ulnar head. The commenter states that the styloid process of the ulna is deep during pronation, but is present during supination. I don't understand. 😕

Thanks a million

you are correct. the styloid process of the ulna is the most medial and distal bone marking. the head is referring to the entire articular surface. you cannot see the "head", referring to the surface anatomy the guy in the video was talking about
