- bicipital groove
- *it contains the long head of the biceps brachia muscle
(humerus) What would happen if we do not have a radial fossa?

(humerus) What does the radial fossa allow us to do?
allows head of the radius to move into the fossa when forearm is flexed

- -allows olecranon to extend into this depression on forearm extension
- *posterior side
(ulna) olecranon process (2)
-fits onto the olecranon fossa upon extension
-forms the point of the elbow
(ulna) What does the trcohlea notch do?
hooks around the trochlea of the humeurs during flexion and extension
(ulna) Where does the coronoid process articulate?
fits onto the coronoid process on the humeus upon elbow flexion
(ulna) which 2 structures hook together to form trochlea notch?
olecranon process and coronoid process
(ulna) What is the ulnar notch?
slight depression whre ulna articulates with distal end of the radius
(radius) what is the radial notch?
- is concave sructure where it articulates with the capitulum of the humerus
- *it is a concave structure
(radius) What is the radial tuberosity?
