|
What types of movement are allowed at the elbow joint? |
flexion/extension and the humero-radial and humero-ulna joint pronation/supination at the proximal radio-ulnar joint |
|
What feature allows some people to hyper extend their arm? |
Some people have an olecranon foramen instead of an olecranon fossa. This allows part of the olecranon to enter the foramen, allowing hyperextension. |
|
ANTERIOR |
A: transverse humeral ligament B: long head of biceps brachii C: short head of biceps brachii D: coracobrachialis E: tendon of biceps brachii F: bicipital aponeurosis |
|
What are the three flexor muscles of the arm? Which of the three is considered to be an accessory flexor? |
Brachialis, biceps brachii and brachioradialis. Brachioradialis is an accessory flexor - it helps flexion when the forearm is mid-pronated. |
|
ANTERIOR |
A: brachialis muscle B: bicipital aponeurosis (cut) C: tuberosity of ulna D: radial tuberosity E: brachioradialis |
|
Which muscle(s) allow extension of the elbow? |
triceps brachii: long, lateral and medial head |
|
|
A: attachment of long head of triceps to infraglenoid tubercle of scapula B: shaft of humerus C: lateral head D: medial head E: long head (cut) F: triceps tendon G: attachment at olecranon process of ulna |
|
Where is the common extensor origin and common flexor origin, respectively. |
Common extensor origin - lateral epicondyle Common flexor origin - medial epicondyle |
|
What attaches to the medial and lateral epicondyles, respectively |
Lateral epicondyle - superficial extensor muscles Medial epicondyle - superficial flexor muscles |
|
What is the correct term for tennis elbow, and what causes it? |
lateral epicondylitis resisting/limiting wrist extension (eccentric) |
|
What is the correct term for golfer's elbow, and what causes it?
|
medial epicondylitis resisting/limiting wrist flexion (eccentric) |
|
What is the common treatment for epicondylitis? |
Rest and injection of corticosteroids if severe |
|
superficial/intermediate layers |
A: common flexor tendon B: pronator teres C: flexor carpi radialis D: palmaris longus E: flexor carpi ulnaris |
|
superficial |
A: anconeus B: extensor carpi ulnaris C: extensor digiti minimi D: extensor digitorum |
|
superficial |
A: common extensor tendon B: extensor carpi radialis longus C: extensor carpi radialis brevis D: extensor retinaculum |
|
What do the following words correspond to; A: opponens B: carpi C: digitorum D: pollicis E: digiti minimi |
A: rotates bone along longitudinal axis B: wrist C: fingers D: thumb E: little finger |
|
What do the following words correspond to;
A: indicis B: profundus C: palmaris D: brevis E: teres |
A: index finger B: deep C: palm D: shorter than something E: rounded or cylindrical |
|

anterior/flexor compartment posterior/extensor compartment |
|
|
A: interosseous membrane B: skin C: shaft of ulna D: shaft of radius E: antebrachial fascia |
|
Which nerve innervates the muscles of the superficial and intermediate muscle layers of the anterior compartment? |
