Multiple Choice
You are playing football and sustain an injury to the elbow. A player on the opposite team applied a pressure to the lateral aspect of the arm. What ligament was likely injured?
Radial Collateral Ligament
Ulnar Collateral Ligament
Annular Ligament of the radius
3
Anterior Fibers: resist extension and vaLgus stress
Posterior Fibers- limits flexion
Transverse fibers: limits valgus/increases stability
vaLgus- LATERAL force - injury to medial aspect
varus- Medical force- injury to later aspect
*this comes back in the knee
4
Multiple Choice
A person comes in with arm pain and is found to have a blood clot in the radial collateral artery, because of anastomoses, blood supply is not lost to that area because of which artery?

M: Lateral border of pronator teres
S: line between epicondyles
L: lateral border of pronator teres
M: Medial border of brachioradialis

Terminal of brachial artery, start of radial/ulnar arteries, Biceps brachii tendon, and median nerve
End of brachial a. start of radial/ulnar aa. brachioradialis tendon, median n.
end of brachial a. start of radial/ulnar aa., biceps brachii tendon, musculocutaneous n.
end of brachial a. start of radial/ulnar aa. biceps brachii tendon ad median n.

Multiple Choice
You want to draw blood for a patient, upon inspection of the cubital fossa, you note the a large, perpendicular vessel on the medical aspect of the arm, which vessel is this?
Basilic v.
Cephalic v.
median cubital vein
ulnar vein
13

Multiple Choice
Which of the following is found in the posterior compartment of the arm
Brachialis m
musculocutaneous n
radial n.
biceps brachii
m
15
Primary movement of the posterior compartment ?? BONUS QUESTION
Hello :)
Posterior Comparment of the arm
: Triceps brachii (3 heads)
Radial n.
16
Multiple Choice
What provides the innervation of the entire anterior compartment of the arm?
radial n
musculocutaneous n
ulnar n
median n
17
Anterior Compartment of the arm: Biceps brachii, (LH and SH), brachialis m, brachial artery, musculocutaneous n
18
Fill in the Blanks
What is the blood supply of Latissimus dorsi?
Type answer...
19
branch of post intercostal
a., & lumbar a.
20
Fill in the Blanks
What are the 2 branches of the subscapular a?
Type answer...
21
Thoracodorsal a and Circumflex Scapular a
22
Fill in the Blanks
What are the actions of Iliocostalis cervicis?
Type answer...
23
Bilaterally: extends spine
For this type of question on the practical its ok if you don't know exactly what muscle it is since they all do very similar actions, so use the question to your advantage
Also don't forget to include uni/bilateral & OC/CC actions
24
Fill in the Blanks
What is the innervation of Pectoralis minor?
Type answer...
25
Make sure you write nerve root levels for innervation
26
Fill in the Blanks
What are the actions of Serratus anterior?
Type answer...
27
28
Fill in the Blanks
What is the innervation of Supraspinatus?
Type answer...
29
30
Fill in the Blanks
What is the distal attachment of the Deltoid?
Type answer...
31
32
Fill in the Blanks
What attaches to the posterior aspect of the conoid tubercle of the clavicle?
Type answer...
33
Don't forget about the ligaments
34
Fill in the Blanks
What are the actions of the lower Trapezius?
Type answer...
35
Make sure you write what body part is doing the action ie Scapular rotation or flexes the shoulder
36
Fill in the Blanks
What is the function of the ligaments in green?
Type answer...
37
Don't forget they can tag models
38
Multiple Choice
What tendon attaches to the Radial Tuberosity?
biceps brachii
Brachialis
Triceps Brachii
Coracobrachialis
39
40
Multiple Choice
What is the most medial muscle of the suboccipital triangle?
Rectus capitus posterior minor
Rectus capitus posterior major
Obliquus capitus inferior
Obliquus capitus superior
41
42
Multiple Choice
Which of the following is an action of the long head of the Triceps brachii?
Humerus adduction
Shoulder flexion
Shoulder extension
Humerus abduction
43
Long head attaches to the infraglenoid tubercle of scapula, therefore it adducts the shoulder
44
Multiple Choice
After a traumatic fall a patient is unable to abduct, externally rotate, and flex the shoulder. Which injury is MOST LIKELY to cause these deficits?
C5 & C6 root avulsion
laceration of posterior cord
Axillary n compression
Inferior trunk impingement
45
Abduct- supraspinatus, deltoid
Ext rot- Infraspinatus, T minor, deltoid
Flex- deltoid, coracobrachialis, biceps
post cord & axillary n- wouldn't explain complete shoulder flexion deficit
inferior trunk- wouldn't explain any of the deficits
46
Multiple Choice
A patient has difficulty fully abducting his shoulder and extending his elbow. Additionally he has lost sensation to his lateral shoulder, posterior arm & forearm and dorsal aspect of the hand & digits 1-3 . What structure is MOST LIKELY injured?
Axillary n
Radial n
Posterior cord
Medial cord
47
Lateral shoulder sensation = axillary
Posterior arm sensation = radial
48
Multiple Choice
A patient presents with loss of sensation to the lateral forearm and weakness of the Pec major, Coracobrachialis, Biceps, Brachialis and some of the wrist flexors, however the rotator cuff muscles have full strength. Where is the lesion?
Lateral cord
Superior trunk
C5 & C6 roots
Muculocutaneous n
49
Start with sensation loss then look at weakness.
Superior trunk & C5/6- RC intact
Musc Cut- won't explain Pec weakness
