Okay so now we're looking at the humorous, your upper arm bone there. Okay so starting at the top of it we have the head of the humorous right here. This is what's articulating with the glenoid cavity of the scapula. Okay then we have a neck. In the humorous cases we technically have two necks. So the neck is kind of where it begins to thin out from the head itself but with the way that the humorous is shaped we have an anatomical neck right at the base of the head here but we also have a surgical neck right here. Okay we've got the greater and lesser tubercles so the greater is kind of higher up on top here. The lesser is kind of a little further down both sticking out projections there. The intertube vehicular socus or groove is in between them. You can see the deltoid tuberosity kind of this roughened part of the humorous. Going down towards the bottom here. So this is kind of where your elbow would be. We have a medial epicondyle. Okay so this is the large projection off to the side. It's your funny bone. It's that part you hit and it hurts like crazy not so funny. Okay and this of course on this side over here would make this our lateral epicondyle. Okay you can see this kind of hole right here. Okay this is the cornoid fossa. And you have two projections here and here on the medial side is the trochliya. On the lateral side is the cappetulum. On the back side another hole here is the alacranin fossa.
