"Describe Erb-Duchenne palsy: typical cause
nerves affected and clinical presentation.","Cause: traction injury to C5-
C6 (upper trunk). Affected: axillary, musculocutaneous, suprascapular.
Presentation: 'waiter's tip' — arm adducted, medially rotated, elbow
extended; loss of shoulder abduction and elbow flexion."
"Describe Klumpke palsy: nerve roots affected and main clinical signs."
"Injury to C8-T1 (lower trunk) — weakness or paralysis of intrinsic hand
muscles, leading to claw hand; possible Horner's syndrome if
sympathetic chain involved."
"List four terminal branches of the posterior cord of the brachial plexus."
"Axillary nerve, Radial nerve, Upper subscapular, Lower subscapular,
Thoracodorsal (note: more than four exist; these are key branches)."
"Which nerve provides the main motor supply to the anterior
compartment of the arm and name its primary muscles?"
"Musculocutaneous nerve — supplies coracobrachialis, biceps brachii,
brachialis (flexors of the elbow)."
,"Explain the classic clinical test for musculocutaneous nerve function."
"Ask patient to flex elbow against resistance (biceps) and test lateral
forearm sensation (lateral cutaneous nerve of forearm) — weakness and
sensory loss indicate lesion."
"Describe the anatomical course and two major functions of the radial
nerve in the arm."
"Courses in radial groove of humerus, supplies triceps (elbow extension),
forearm extensors (wrist/digit extension), and cutaneous innervation to
posterior arm/forearm and dorsum of hand."
"What is the typical presentation and cause of a radial nerve palsy at the
spiral groove?"
"Cause: mid-shaft humeral fracture. Presentation: wrist drop (loss of
wrist/digit extension), weakened elbow extension if proximal, sensory
loss over posterior forearm/dorsum of hand."
"Which artery is the main blood supply of the upper limb and name its
major named segments from axilla to cubital fossa."
"Axillary artery (continuation of subclavian) → becomes brachial artery at
inferior border of teres major; brachial divides into radial and ulnar
arteries at cubital fossa."
"List the three parts of the axillary artery and one branch from each part."
"Part 1 (proximal to pectoralis minor): superior thoracic artery. Part 2
(posterior to pectoralis minor): thoracoacromial trunk, lateral thoracic
artery. Part 3 (distal): subscapular, anterior and posterior circumflex
humeral arteries."
,"Describe the typical site and clinical importance of the subscapular
artery."
"Branch of third part of axillary artery; gives circumflex scapular and
thoracodorsal arteries — important in scapular anastomoses and
latissimus dorsi blood supply used in flaps."
"Name the major anastomoses around the scapula."
"Transverse cervical/dorsal scapular with suprascapular and circumflex
scapular arteries (collateral supply between subclavian and axillary
arteries)."
"Identify the boundaries and contents of the axilla."
"Boundaries: apex (clavicle/1st rib/scapula), base (axillary fascia/skin),
anterior wall (pectoralis major/minor), posterior wall (subscapularis/teres
major/latissimus), medial (thoracic wall), lateral (intertubercular sulcus).
Contents: axillary artery/vein, brachial plexus cords, axillary lymph nodes,
fat."
"Which lymph nodes receive lymph from the lateral quadrants of the
breast and superficial upper limb?"
"Axillary (pectoral, central, apical) lymph nodes, particularly the pectoral
group for lateral breast and superficial upper limb via cephalic vein
drainage area."
, "Trace the cephalic vein from origin to termination."
"Originates from lateral dorsal venous network of hand → courses in
lateral forearm/arm → runs in deltopectoral groove → drains into axillary
vein (via deltopectoral triangle)."
"Explain the importance of the median cubital vein clinically."
"Superficial communicating vein between cephalic and basilic in cubital
fossa; common site for venepuncture/IV access due to stability and
accessibility."
"Name the muscles forming the anterior compartment of the forearm
(superficial layer) and one action for each."
"Pronator teres (pronation, elbow flexion), Flexor carpi radialis (wrist
flexion & radial deviation), Palmaris longus (tenses palmar aponeurosis),
Flexor carpi ulnaris (wrist flexion & ulnar deviation), Flexor digitorum
superficialis (PIP flexion)."
"Which nerve usually innervates the majority of the anterior forearm and
what are key exceptions?"
"Median nerve innervates most anterior forearm muscles; exceptions:
Flexor carpi ulnaris and medial half of flexor digitorum profundus are
innervated by ulnar nerve."
