Question 1

What is this: the lateral portion of the scapular region, where the scapular joins with the clavicle and the humerus and where the region is covered by the rounded mass of the deltoid muscle

Answer 1

shoulder

Question 2

What muscles make up the rotator cuff?

Answer 2

subscapularis
infraspinatus
teres minor
supraspinatus

Question 3

What is unusual about the coracoacromial ligament?

Answer 3

it goes from one part of the scapular to another!

Question 4

What are these symptoms of:
Shoulder pain and tenderness, especially when reaching overhead,                           	reaching to the back, lifting, sleeping on affected side
  Shoulder weakness
  Loss of shoulder range of motion
  Inclination to keep shoulder inactive

Answer 4

rotator cuff injury

Question 5

What are the causes of rotator cuff injury?

Answer 5

Tendinitis (often due to overuse or overload)

Bursitis (irritation, inflammation, and attrition of supraspinatus tendon and wall of subacromial bursa

Question 6

What are risk factors of rotator cuff injury?

Answer 6

age (over 40)
being an athlete
construction worker
poor posture and weak shoulder muscles

Question 7

How do you fix a rotator cuff via surgery?

Answer 7

surgical acromioplasty
subacromial bursectomy
rotator cuff reconstruction

Question 8

What is this:

tendons become entrapped under the acromian; compression, injury, rotator cuff tendonitis

Answer 8

rotator cuff impingement syndrome

Question 9

A rotator cuff injury with attrition (wearing away by friction or rubbing) of the supraspinatus tendon, results in (blank)

Answer 9

degenerative tendonitis

Question 10

Where is there a potential space at the axillary area?

Answer 10

between the rib and the serratus anterior

Question 11

Where is the serratus anterior attached to the scapula?

Answer 11

at the medial border

Question 12

How can you tell someone has serratus anterior paralysis?

Answer 12

you have winged (protruding) scapula on affected side

Question 13

Injuries to the (blank) will affect the important function of the serratus anterior muscle. The muscle can no longer protract the scapula or abduct the arm completely.

Answer 13

long thoracic nerve

Question 14

How do you damage the LT nerve?

Answer 14

it runs vertical and superficial so it can be stabbed, or crushed or screwed up surgery (construction workers get it a lot)

Question 15

Where is the basilic vein?
where is the cephalic vein?
Why are these important?

Answer 15

near the pinky side of the forearm (ulnar)
near the thumb side of the forearm (radial) and lies between the groove of the deltoid and pectoralis major
This is where you draw blood and inject things into.

Question 16

Why do they call the cephalic vein the cephalic vein?

Answer 16

because it runs high up towards the encephaly (brain)

Question 17

What does the cephalic vein run through?

Answer 17

it runs through the costocoracoid membrane (investing fasciae for pectoralis major and minor) and joins with axillary vein

Question 18

What are the lymph nodes in the arm (wrist towards upper arm)?

Answer 18

cubital nodes-> lateral axillary nodes-> deltopectoral nodes

Question 19

Are the lymph nodes in the hand?

Answer 19

no

Question 20

lymphatics surround the (blank) vein and the (blank) nerve

Answer 20

axillary vein

long thoracic

Question 21

Lymphatic drainage on the left side is through the (blank)

Answer 21

thoracic duct

Question 22

What makes this happen:
sternocleidomastoid pulls medial end of clavicle up, gravity pulls lateral end of clavicle down. Pectoralis major pulls humerus medially and underneath the fractured ends of the clavicle.

Answer 22

fracture of the clavicle

Question 23

What is this:
Fracture results from fall on the point of the shoulder. Three (3) rotator cuff muscles
remain attached to the torn-off greater tubercle. The subscapularis, that remains
attached to the lesser tubercle of the humerus, pulls the limb into medial rotation.

Answer 23

avulsion fracture of the greater tubercle of the humerus

Question 24

(blank) attach to greater and lesser tubercle of the humerus. Intertubercular groove is the attachment site for (blank)

Answer 24

Rotator cuff tendons

biceps brachii tendon

Question 25

What should you be worried about if you have shaft fracture?

Answer 25

the radial nerve :(

Question 26

What should you be worried about if you have fracture at the distal end of the humerus?

Answer 26

median nerve

Question 27

the (blank) nerve is vulnerable near the medial epicondyle so you should be worried about this nerve if you had a fracture here.

Answer 27

ulnar

Question 28

What kind of fracture is this:

lateral pull of deltoid, upward pull of bicep

Answer 28

transverse fracture of shaft of humerus

Question 29

What is the chief extensor of the forearm?

Answer 29

triceps brachii

Question 30

The triceps brachii is distally
attached to the (blank)
of the ulna

Answer 30

olecranon

Question 31

Fracture-separation of the (blank) is common in children

because of frequent falls

Answer 31

distal radial epiphysis

Question 32

If you have a fall on your hand, which forearm bone will be affected?
The injury will then be transmitted to whichforearm bone once you get close to the elbow?

Answer 32

radius

ulna

Question 33

A complete transverse fracture of the distal 2 cm of the radius is called a (blank).
It is the most common fracture of the forearm, particularly in adults over 50 and in women with osteoporosis

Answer 33

Colles fracture

Question 34

What is scapula Steal syndrome?

Answer 34

where blood is stolen from scapula to supply the brachial artery

Question 35

If there is a subclavian artery occulsion proximal to origin of vertebral artery: the subclavian artery steals arterial blood from the (blank),causing symptoms (dizziness, unsteadiness, vertigo, visual changes, ischemia of upper limb, difference in right and left radial pulse, intermittend claudication [attacks of lameness and pain] in upper limb)

Answer 35

basilar artery
