Q

Biceps brachii

Origin
Insertion
Innervation
Action

A

Origin - long head: supraglenoid tubercle of scapula
Short head: coracoid process of scapula

Insertion - common tendon on radial tuberosity and bicipital aponeurosis

Innervation - musculocutaneous

Action - flexes and supinate forearm at elbow; flexes arm at glenohumeral joint

Q

Triceps brachii

Origin
Insertion
Innervation
Action

A

Origin: long head- infraglenoid tubercle of scapula
Lateral head- lateral and posterior surface of humerus, superior to radial groove for radial nerve
Medial head- posterior surface of humerus, inferior to radial groove

Insertion: via a broad, strong tendon onto the olecranon process of ulna

Innervation: radial nerve

Action: extension of forearm; long head may assist in extension of arm

17
Q
  1. Where does the axillary artery change name to the brachial artery?
  2. Travels ___ to coracobrachialis and short head of biceps
  3. Lies __ of cubital fossa
  4. ___ to biciptial aponeurosis
A
  1. Distal to the inferior border of teres major muscle
  2. Medial
  3. In center
  4. Deep
18
Q

Brachial artery terminates and divides into __ and __

Where?

A

Radial and ulnar arteries

1 cm inferior to bend of the elbow within the cubital fossa

19
Q

3 major branches of the brachial artery

A

Deep brachial (profunda brachii), superior ulnar collateral, and inferior ulnar collateral

20
Q

Deep brachial artery divides to what two arteries?

A

Middle collateral artery and radial collateral artery

21
Q

Where would you place a tourniquet?

A

Distal to the inferior ulnar collateral artery

22
Q
  1. What do deep veins of the arm do?
  2. __ and __ join to form 2 brachial veins
  3. The 2 brachial veins ascend on each side of the ____ and anastomose freely with one another
  4. Terminate where?
A
  1. Drain blood from deep tissue of both flexor and extensor compartments of the arm
  2. Radial and ulnar vein
  3. Brachial artery
  4. Terminate in the axillary vein (so 2 brachial veins + basilic vein = axillary vein)
23
Q
  1. Why is the musculocutaneous nerve rarely injured?
  2. If it is injured, where would it usually be?
  3. What would happen?
A
  1. Is it deep to the biceps brachii
  2. High up in the arm (usually by weapon)
  3. The flexor compartment of the arm would be paralyzed, could also lose sensation on the lateral surface of the forearm (because thats innervated by lateral cutaneous nerve which used to be musculocutaneous)
24
Q

What 2 nerves do not innervate any muscles of the arm?

Fracture of what could injure median nerve?

Fracture of what could injure ulnar nerve?

Which of these nerves is the funny bone?

A

Median and ulnar nerve (only forearm)

Supracondylar fracture

Medial epicondyle

Ulnar= funny bone

25
Q

Fractures where could injure the radial nerve?

Where would you see the affect of radial nerve injury?

A

Fracture of the distal portion of the shaft of the humerus

Injury to radial nerve will not affect the arm, but will affect the forearm and hand
