Lecture 11: Completion

Question 1

Median nerve route

Answer 1

Crosses anterior cubital fossa medial to brachial artery
Passes between heads of pronator teres
Travels b/w flexor digitorum superficialis and profundus

Question 2

Ulnar nerve route

Answer 2

From posterior compartment of brachium
Through sulcus in medial epicondyle
Into antebrachium between two heads of flexor carpi ulnaris
Extends between flexor carpi ulnaris and flexor digitorum profundus

Question 3

Radial nerve route

Answer 3

Runs in radial groove and extends down lateral side of humerus
Pierces lateral intermuscular septum and enters antebrachium between brachioradialis and brachialis
Passes in front of lateral epicondyle, enters cubital fossa
Divides into superficial and deep branches

Question 4

Ulnar artery joined by ____ nerve in middle third of forearm

Answer 4

Ulnar nerve

Question 5

Ulnar artery lies where in middle third of forearm

Answer 5

Underneath flexor carpi ulnaris

Question 6

Ulnar artery location in distal third of forearm

Answer 6

Superficial/lateral to tendon of flexor carpi ulnaris

Adjacent/lateral to ulnar nerve

Question 7

Ulnar artery in relation to flexor retinaculum

Answer 7

Passes flexor retinaculum superficially

Question 8

Branches of ulnar artery

Answer 8

Anterior ulnar rec-inferior ulnar collateral
Posterior ulnar rec-superior ulnar collateral
Common interosseous-ant/post interosseous
Deep branch joins palmar arch
Curves laterally to form superficial palmar arch

Question 9

Radial artery

Answer 9

Proximally lies deep to brachioradialis
Distally becomes superficial between brachioradialis and flexor carpi radialis
Winds dorsally through anatomical snuff box
Pierces first dorsal interosseous muscle

Question 10

Branches of radial artery

Answer 10

Radial recurrent
Dorsal carpal artery
Dorsal metacarpal and digital arteries
First dorsal metacarpal

Question 11

After passing through the first dorsal interosseous muscle, the radial artery gives off

Answer 11

The princeps pollicis artery to the thumb

Forms complete arch across palm, joins ulnar artery on medial side

Question 12

Medial collateral ligament

Answer 12

Medial epicondyle to coronoid and olecranon process

Slack ligament results in valgus deformity

Question 13

Lateral collateral ligament

Answer 13

Lateral epicondyle to annular ligament and olecranon process

Slack ligament results in varus deformity

Question 14

Annular ligament

Answer 14

Attached to ulna

Forms sling around neck of radius

Question 15

Close-packed position

Answer 15

Extension

Question 16

Axes of carrying angle/elbow joint

Answer 16

Longitudinal axis of humerus

Long axis through trochlea

Question 17

Deviation of antebrachium

Answer 17

5 degree lateral deviation in men

10-15 degree lateral deviation in women

Question 18

Increase in deviation is called

Answer 18

Cubitus valgus

Question 19

Decrease in deviation is called

Answer 19

Cubitus varus

Question 20

Ulnar nerve runs posterior to

Answer 20

Medial epicondyle

Question 21

Bicipital aponeurosis to median cubital vein and brachial artery

Answer 21

Brachial artery runs beneath bicipital aponeurosis

MCV extends diagonally across bicipital aponeurosis

Question 22

Median nerve to brachial artery

Answer 22

Medial to brachial artery in cubital fossa/lower half brachium
Lateral to brachial artery in upper half of brachium
