Upper limb

Question 1

Brachial plexus

Answer 1

draw it out

Question 2

structures passing through the clavipectoral fascia

Answer 2

CALL
Cephalic vein A -thoracoAcrominal artery Lymphatics Lateral pectoral nerve

Question 3

Quadrangular space + contents

Answer 3

Boundaries
Superior: teres minor (inferior margin)
Inferior: teres major (superior margin)
Medially: long head triceps brachii (lateral margin)
Laterally: Surgical neck of the humerus
Anteriorly: subscapularis

Contents:
Axillary nerve and posterior circumflex humeral vessels (artery and vein)

Question 4

Triangular space

Answer 4

Boundaries
Inferior: superior border of teres major
Lateral: long head of triceps
Superior: teres minor (or subscapularis)
Contents: Scapular circumflex vessels
Unlike the quadrangular space or the triangular interval, NO major nerve passes through the triangular space

Question 5

Triangular interval

Boundaries
Superior: teres major
Medial: long head of triceps brachii
Lateral: humerus (some sources say lateral head of triceps)
Contents

Radial nerve passes through on its way to the posterior compartment of the arm. Profunda brachii also passes from anterior to posterior.

Answer 5

Boundaries
Superior: teres major
Medial: long head of triceps brachii
Lateral: humerus (some sources say lateral head of triceps)
Contents

Radial nerve passes through on its way to the posterior compartment of the arm. Profunda brachii also passes from anterior to posterior.

Question 6

Axillary artery branches

Answer 6

SEND THE LORD A PRAYER STAT

1st part of axillary artery gives off (1) the superior thoracic artery

2nd part gives off (2) the thoraco-acromial trunk and lateral thoracic artery
3rd part gives off (3) sub-scapular artery and anterior/posterior humeral circumflex artery.

Question 7

Anatomical snuff box boundaries and contents

Answer 7

radial: abductor pollicis longus and the extensor policis brevis that form one boundary on the radial or thumb side, and the extensor pollices longus forms the other boundary on the ulnar side.

Contents: radial artery, cephalic vein (begin in roof) and cutaneous branches of the radial nerve

Question 8

Bony features
Corocoid process of scapula
Coronoid process of ulna
Radial notch of ulna
Coronoid process of mandible

Question 9

Ligaments of sternoclavicular joint

Answer 9

anterior and posterior sternoclavicular ligament + interclavicular ligament - strength to joint
only x1 fibrocartilaginous joint
costoclavicular joint stabilise on limiting elevation acting as an anchor
supplied by C3,C4
Innervated by ateral pectoral nerve, axillary nerve and lateral supraclavicular nerve

Question 10

Brachial artery

Answer 10

Continuation of axillary artery
Median nerve lies lateral to it in upper arm before crossing over in the antecubital fossa . Passes anterior to medial epicondylar area at the elbow joint

Question 11

Cubital Fossa boundaries and contents (medial to lateral)

Answer 11

skin / epicondylar spaces
pronater tere s medially and brachioradialis laterally
- medial to laterla
- median nerve&raquo_space; brachial artery (vein medial)&raquo_space; biceps tendon&raquo_space; radial nerve (superficial part)

Question 12

Carpal tunnel Boundaries and contents

Answer 12

Roof - flexor retinaculum spans between the hook of hamate and pisiform (medially) to the scaphoid and trapezium (laterally) to form the roof of the carpal tunnel
PL (superficial) FCU (medial, inserts into tendon) and FCR (radial, own sheath) outside of canal
Guyon’s canal for ulnar artery and nerve

Question 13

Confusing names of bones
Coronoid fossa of the humerus
Coronoid process of the ulna
Trochlear of the humerus T
Trochlea notch (or fossa) of the ulna
Radial notch - ulna
Radial tuberosity on the radius
