Answer 9

Interosseous Membrane

Question 10

Carpals that articulate with radius

Answer 10

Scahpoid, Lunate

Question 11

Boxer’s fracture

Answer 11

Occurs when a punch focuses the force of impact on last digits rather than 2 and 3, which are supported by the two carpals and the rest of the arm.

Question 12

How does carpal tunnel syndrome occur?

Answer 12

Repetitive hand movements cause the tendons of the sulcus carpi (located under flexor retinaculum) to become inflamed, putting pressure on the median nerve.

Question 13

Only saddle joint

labrum means

Answer 14

lip (of fibrocartilage)

Answer 17

Glenoid cavity

Answer 19

Biceps braciii, Pectoralis major, Coracobrachialis

Question 20

Extends arm at shoulder

Answer 20

Latissimus dorsi

Question 21
