If he did have webs as part of his super hero powers, the webs would probably come out of his butt and not his wrist.
OK, that's a mental image I really didn't want. My day is ruined now.

Like the story said, the movies didn't want to get into the development of them, so took the simpler explanation of "he's part spider, duh!" I did however, like the scene where the camera zoomed in on the barbs on his palms that let him grasp buildings, etc.
But I believe there have been versions of the character that had organic webbing, but it's been a while for me so I don't know what the latest ideas are.
