what process is on the inferior lip of the trochlea notch?

Answer 25

coronoid process

Question 33

what is the fibrous sheet that connects lateral margin of ulnar shaft to radius?

Answer 33

interosseous membrane

Question 34

what happens when the elbow flexes?

Answer 34

coronoid process enters coronoid fossa of the humerus

Question 35

what happens when the elbow extends?

Answer 35

olecranon process enters olecranon fossa of the humerus
