Muscles - Upper Limb Sheet. Every upper limb structure on one sheet - muscles, bones, nerves, and vessels, each in its own table with its own columns.
Muscle	Origin	Insertion	Action	Innervation	Blood supply
Abductor digiti minimi (hand)	Pisiform and the tendon of flexor carpi ulnaris	Medial base of the proximal phalanx of the little finger	Abducts the little finger	Deep branch of the ulnar nerve (C8, T1)	Deep palmar arch / ulnar artery
Abductor pollicis brevis	Flexor retinaculum, scaphoid, and trapezium	Lateral base of the proximal phalanx of the thumb	Abducts the thumb at the carpometacarpal and MCP joints	Recurrent branch of the median nerve (C8, T1)	Superficial palmar branch of the radial artery
Abductor pollicis longus	Posterior surfaces of the ulna, radius, and interosseous membrane	Base of the 1st metacarpal	Abducts and extends the thumb at the carpometacarpal joint	Posterior interosseous nerve (C7, C8)	Posterior interosseous artery

Bones - Upper Limb Sheet. Every upper limb structure on one sheet - muscles, bones, nerves, and vessels, each in its own table with its own columns.
Bone	Bone type	Key landmarks	Articulations
Clavicle	Long (atypical - no medullary cavity)	Sternal (medial) end; Acromial (lateral) end; Conoid tubercle; Trapezoid line; Subclavian groove	Sternum (sternoclavicular joint); Acromion of scapula (acromioclavicular joint)
Humerus	Long	Head; Anatomical and surgical necks; Greater and lesser tubercles; Intertubercular (bicipital) groove; Deltoid tuberosity; Radial (spiral) groove; Medial and lateral epicondyles; Capitulum; Trochlea; Olecranon, coronoid, and radial fossae	Scapula (glenohumeral joint); Radius and ulna (elbow joint)
Lunate	Short (carpal)	Concave distal surface; Convex proximal surface	Radius; Scaphoid; Triquetrum; Capitate; Hamate

Nerves - Upper Limb Sheet. Every upper limb structure on one sheet - muscles, bones, nerves, and vessels, each in its own table with its own columns.
Nerve	Roots	Course	Motor	Sensory
Axillary nerve	C5, C6 (posterior cord)	Passes through the quadrangular space with the posterior circumflex humeral artery, winding around the surgical neck of the humerus	Deltoid and teres minor	Skin over the inferior deltoid ('regimental badge' area) via the superior lateral cutaneous nerve of the arm
Long thoracic nerve	C5, C6, C7 (roots of the brachial plexus)	Descends on the external surface of serratus anterior along the mid-axillary line	Serratus anterior	No cutaneous sensory territory - this nerve is purely motor.
Median nerve	C6, C7, C8, T1 (lateral and medial cords)	Descends through the arm lateral then medial to the brachial artery, passes between the two heads of pronator teres, and travels through the carpal tunnel into the hand	Most anterior forearm flexors (except FCU and medial FDP), thenar muscles, and lateral two lumbricals	Palmar lateral 3½ digits and their nail beds; lateral palm

Vessels - Upper Limb Sheet. Every upper limb structure on one sheet - muscles, bones, nerves, and vessels, each in its own table with its own columns.
Vessel	Type	Origin	Branches / tributaries	Course	Supplies	Drains
Axillary artery¹	Muscular artery	Subclavian artery	Superior thoracic; Thoracoacromial; Lateral thoracic; Subscapular; Anterior and posterior circumflex humeral arteries	Runs from the outer border of the first rib through the axilla, becoming the brachial artery at the inferior border of teres major	Shoulder region, axilla, and proximal upper limb	not recorded
Brachial artery¹	Muscular artery	Axillary artery	Deep brachial (profunda brachii) artery; Superior and inferior ulnar collateral arteries; Radial and ulnar arteries (terminal)	Descends medially in the arm, crosses the cubital fossa medial to the biceps tendon, and bifurcates at the level of the radial neck	The arm and (via terminal branches) the forearm and hand	not recorded
Radial artery¹	Muscular artery	Brachial artery (in the cubital fossa)	Palmar and dorsal carpal branches; Superficial palmar branch; Princeps pollicis artery	Descends along the lateral forearm, crosses the floor of the anatomical snuffbox, and passes between the heads of the first dorsal interosseous into the palm	Lateral forearm, wrist, and hand (mainly the deep palmar arch)	not recorded
