Joints

Question 1

What type of joint is it?

Answer 1

Synovial hinge joint (uniaxial)

Question 2

What movement is the elbow joint?

Answer 2

flexion 140-150 degrees

extension 0-5 degrees

Question 3

What movement is the radial-ulnar joint?

Answer 3

Pronation and supination

Question 4

What are surfaces covered in?

Answer 4

articular surfaces are covered in hyaline cartilage

Question 5

Humero ulnar joint

Answer 5

between the trochlea of the distal humerus and the trochlear notch of the ulna

Question 6

Humero radial head

Answer 6

between the proximal radial head and capitulum of distal humerus

Question 7

Superior radio ulnar joint

Answer 7

Between the head of the radius and the radial notch of the ulna
synovial pivot joint
stabilises radial ulna joint
inner surface lined with synovial membrane
fibrous joint

Question 8

What is the elbow capsule?

Answer 8

Attached around the edge of the ulnar articular surfaces including the radial notch

Question 9

Attachments of the ulnar collateral ligament

Answer 9

Medial epicondyle and proximal ulna

Question 10

Attachments of the radial collateral ligament

Answer 10

lateral epicondyle and radial head

Question 11

What is the olecranon Bursa?

Answer 11

Facilitates smooth movement of the skin over the olecranon process during flexion and extension

Question 12

What is the carrying angle?

Answer 12

Medial edge of trochlea projecting distally
15 degrees between arm and forearm into abduction
disappears on full flexion and pronation in full extension

medial border of the brachioradialis
Lateral border of the pronator teres
line drawn between the 2 epicondyles
within this are the biceps tendon, tendon of brachial, brachial artery and median nerve
