Document Summary

There"s a point where the radius rolls into the radial fossa which stops/limits the flexion. At full flexion the coronoid process fits into the coronoid fossa. Posterior side only has 1 fossa (rather large): olecranon fossa: portion of proximal ulna (called the olecranon process) fits into the olecranon fossa. At full extension of the elbow, olecranon process sits in the olecranon fossa, so you can extend any more. Funny bone is actually your medial epicondyle (nerve runs over it and when you hit it all the muscles it innervates tingle. Just down from the heads of each we have the tuberosities. Radial tuberosity (bicipital tuberosity) - where the bicep attaches. Ulnar tuberosity (attachment for the triceps muscle (brachialis) The triceps is more powerful then the biceps. Both the ulna and radius have a styloid process. Looking at this image from the medial to lateral. We know this because there"s 2 fossa that are anterior.
