1

The elbow joint includes these two articulations

A hinge joint and a plane joint

2

The hinge joint of the elbow is between the

Trochlea of the humerus and the trochlear notch of the ulna

3

The plane joint of the elbow is between the

Capitulum of the humerus and a shallow depression (fovea) on the head of the radius

4

A thick band of dense connective tissue, located in the medial wall of the capsule

The ulnar collateral ligament

5

The posterior part of the ulnar collateral ligament is attached to the

Medial epicondyle of the humerus and to the olecranon process of the ulna

6

A fibrous band extending between the lateral epicondyle of the humerus and the anular ligament of the radius; strengthens the lateral wall of the joint capsule

Radial collateral ligament

7

The synovial membrane that forms the inner lining of the elbow capsule projects into the joint cavity between the radius and ulna and partially divides the joint into

Humerus-ulnar and humerus-radial portions

8

What type of movements are the only type that can occur at the elbow between the humerus and ulna

Hinge-type movements - flexion and extension

9

The head of the radius is free

Rotate in the anular ligament
