Skeletal system: Radius and ulna

Question	Answer
Where is the ulna in comparison to the radius	On the inside, in anatomical position
What t who bones does the Ulna articulate with	Proximally the ulna articulates with the trochlea of the humerus, Distally the ulna articulates with the radius
In this proximal region of the ulna which area is shaded yellow Image: Mobile upload (image/jpeg)	Trochlea notch
In this proximal region of the ulna which area is shaded green Image: Mobile upload (image/jpeg)	Olecranon process
In this proximal region of the ulna which area is shaded blue Image: Mobile upload (image/jpeg)	Radial notch
In this proximal region of the ulna which area is shaded red Image: Mobile upload (image/jpeg)	Coronoid process
Where does the radius articulate	Elbow joint – Partly formed by an articulation between the head of the radius, and the capitulum of the humerus. Proximal radioulnar joint – An articulation between the radial head, and the radial notch of the ulna. Wrist joint – An articulation between the distal end of the radius and the carpal bones. Distal radioulnar joint – An articulation between the ulnar notch and the head of the ulna.
