Answer 2

Flexor Carpi Ulnaris

Extensor Carpi Ulnaris

Question 3

Where does the radius articulate with the humerus?

Answer 3

The capitulum, anchored by the annular ring surrounding head of the radius

Question 4

Where does the ulna articulate with the humerus?

Answer 4

Olecranon
Coronoid process
Trochlear Notch
—-This is a stronger articulation than the radius

Question 5

Where does the radius articulate at the wrist?

Answer 5

Scaphoid and lunate carpal bones

Question 6

Which styloid process extends more distally? Radius vs. Ulna

Answer 6

Styloid process of the radius extends more distally

—provides clues for injuries

What is Colles Fracture?

Answer 7

Fx of the styloid process of the radius & proximal displacement

• —palpation would indicate styloid processes at same level
• –scaphoid bone could be damaged too
