so now we're going to look at the bones of our forearm and so these two bones this is the ulna and this one here is the radius they're easily distinguishable from each other because the ulna has this kind of scoop structure on it some people say it looks like an ice cream scoop some people say it looks like a wrench but that is the ulna with the radius kind of ends in this kind of knob like structure there so now let's take a look at the structures on this when i look at the almond here first i'm going to bring back the humerus to show how they correlate with each other so on the ulna here we have this sorry this structure here and that is called the oliprinon process so let me go ahead and zoom in here so this process right there is a leprenon process this is your coronoid process if you look at the humerus again this fossa here was called the oliperinon fossa this fossa here was called the corner faucet and so that's where those structures go into each other so the oligodon fossa here goes into the olympian process or they're looking unprocessed goes into the liquid on fossa the corn head process goes into the cornrow fossa the scoop part here is called the trochlear notch so this part on the universe is called the trochlea and the trochlear notch goes into that this little notch right here is called the radial notch because that's where the head of the radius will rest ahead of the radius let's rest right there in the radial notch now at the other end of the ulna we see it sticks out a little bit and that little point there is called the styloid process of the ulna that's looking at the ulna there let's go ahead and move on to the radius so i said already that the radius has this little knob like structure and that knob like structure there is called the head of the radius so that is the head of the radius this right here this little rough structure right there that is called the radial tuberosity so that is where our biceps brachii attaches to the radius so that is the radial tuberosity and then at the other end here you're going to see another little pointy process there and that is the styler process of the radius lastly let's go ahead and move on to the bones of our wrist and hand so these bones that make up our wrist bones those are the carpals these bones that make up the middle of our hand essentially the palms of our hand there those are the metacarpals and then these three bones here on each of these fingers and we only have two on our thumbs those are the phalanges of the hand so three on each finger except for the thumb so once again these are the phalanges of the hand so cardboards metacarpals phalanges and
