Articulates with head of radius
On lateral side of humerus
More rounded

Question 5

Articulation with the trochlear notch of the ulna
On medial side of humerus
Not the rounded one

Question 6

Coronoid process

Answer 6

Recieves coronoid process of the ulna during full flexion of the elbow
On anterior side of humerus

Question 7

Olecranon fossa

Answer 7

For olecranon process of ulna during extension of elbow

On posterior side

Question 8

Radial fossa

Answer 8

Accommodates the edge of the head of radius when elbow is fully flexed

Question 9

What is the stabilizing bone of the forearm?

Answer 9

Ulna

Question 10

What are the landmarks of the ulna

Answer 10

At the proximal end
	Anteriorly-coronoid process	
	Posteriorly-olecranon process
Inferior to coronoid-tuberosity of ulna
Lateral to coronoid-radial notch(for head of radius)
Distal end-ulnar styloid process

Both forms the wall of the trochlear notch

Question 11

Answer 11

Cylindrical head
Radial tuberosity
Radial styloid process, larger than ulna and farther down

Question 19

Brachial fascia

Answer 19

Covers arm like sleeve continuous superiorly with deltoid, pectoral, axillary and infraspinous fascia

Question 20

Medial and lateral intermuscular septa

Answer 20

Answer 21

In forearm, seperated y the interosseous membrane connecting the radius and the ulna

Question 22

Extensor retinaculum

Flexor retinaculum

Answer 22

• transverse bangs which holds the extensor tendons in position
• continuation of antebrachial fascia
