Elbow joint Flashcards
identify on your skeleton where the following regions of the inferior humerus are
medial epicondyle, lateral epicondyle, capitulum, radial fossa, coronoid fossa, olecranon fossa, groove for ulnar nerve.
identify on your skeleton
the radial tuberosity, the neck of the radius and the articular area of the proximal radius
identify on your skeleton
corocoid process, radial notch, sublime tubercle, the olecranon.
what does the quadrate ligament do
connects the radius to the ulna
what does the annular ligament do
provides the radius stability when it is spinning
what does the interosseous membrane do
provides stability
