Flashcards in General Arm/Forearm Questions Deck (28):
1

Erb-Duchenne paralysis

Medial rotation of the arm (lateral pectoral and suprascapularis nerve affected, pectoralis major and infra/supraspinatus), lateral aspect of forearm may be affected (musculocutaneous, lateral antebrachial cutaneous nerve) and well as the muscles innervated by the musculocutaneous nn (coracobrachialis, biceps brachii, brachialis).

2

Winged Scapula, which parts of the brachial plexus injured

C5,C6,C7- wings to heaven. roots of the brachial plexus

3

Flexor digitorum profundus flexes which part of the fingers?
Flexor digitorum superficialis?

DISTAL interphalangeal
DIP. DIG.
Superficialis-- proximal interphalangeal

4

Anterior wall of the axilla

Pectoralis Minor

5

Median nerve innervation

Pronator teres, pronator quadratus, and skin over the anterior aspect of the thumb
flexors (flexor carpi ulnaris, palmaris longus, flexor carpi radii, flexor digitorum superficialis, flexor digtorum profunus, flexor pollicis longus)

6

Radial Nerve Injury

Fracture at midshaft of humerus, wrist job due to lack of extension of the arm/forearm

7

Contents of the cupital fossa from medial to lateral

Median nerve, brachial artery, biceps brachii tendon, radial nerve

8

Injury to Median Nerve

Ape hand (thumb permanently extended)

9

Damage to the ulnar nerve

Claw hand and flattening to the hypothenar eminence

10

What lies superficial to the flexor retinaculum

ulnar nerve, ulnar artery, palmaris longus tendon, and palmar cutaneous branch of the median nerve

11

If brachial artery were ligated at its origin, what would supply blood to the profunda brachii?

posterior humeral circumflex

12

what two fingers does the medial nerve supply?

median--flexor, anterior compartment, lateral two lumbercals--index and middle fingers

13

What muscles can supinate the forearm?

biceps brachii (musculocutaneous) (anterior compartment)
supinator (radial) (posterior compartment)

14

Funny bone syndrome

Ulnar nerve-- posterior and dorsal surface of medial third of the hand and the medial one and one half fingers.

15

What runs with the radial nerve distal to the cubital fossa?

Deep brachial artery

16

Nerves and their relationship to Humeral injuries

surgical neck--axillary
Radial grove-radius
Distal end- median
medial epicondyle--ulnar nerve (biceps brachii runs to the olecranon)

17

Glenohumeral Joint

Transverse ligaments support biceps brachii long head
Coracoacromial bursa---Bursitis (trouble abduction)
Subscapular bursa

18

Shoulder Seperation

Disruption of the acrolioclavicular joint and the coracoacromial ligament--can also develop bursitis and cause pain with shoulder abduction

19

Two Aspects of the Coracoclavicular Ligaments

Coniod and Trapezoid

20

Which ligament of the elbow is seen on the lateral side

Radial collateral (and anular)

21

which ligament of the elbow is seen on the medial side

ulnar ligament

22

blood supply to trapezius

transverse cervicle

23

Latissimus dorsi artery and nerve

thoracodorsal artery and nerve

24

Origins of the Biceps brachii

long head--supraglenoid tubercle
short head--coracoid process

25

Infraglenoid and supraglenoid tubercles of scapula (muscles_

Supraglenoid-- long head of biceps brachii
Infraglenoid --long head of triceps brachii

26

Flexor digitorum Superficialis

Anterior interosseous nerve and artery
PIP (proximal interphalangeal joints)
wrist, and metacarophalangeal

27

Median nerve problems in hand

cannot flex the PIP of the 1-3rd digits, and the DIP of the 4th and 5th

28

Ulnar Nerve Problems in Hand and wrist

Cannot flex the 4th and 5th digits (DIP)
