Muscles

Muscles - Upper Limb Sheet. Every upper limb structure on one sheet - muscles, bones, nerves, vessels and the rest, each type in its own table with its own columns.
MuscleOriginInsertionActionInnervationBlood supply
Abductor digiti minimi (hand)Pisiform, with attachment to the flexor carpi ulnaris tendonUlnar side of the fifth proximal phalanx at its baseMoves the fifth finger away from the ring fingerDeep ulnar nerve branch, mainly C8–T1Muscular branches of the ulnar artery
Abductor pollicis brevisFlexor retinaculum and the scaphoid and trapezium tuberclesRadial side of the thumb's proximal phalanx at its baseProduces palmar abduction of the thumbRecurrent median nerve branch, mainly C8–T1Radial artery, through its superficial palmar branch
Abductor pollicis longusBack of the radius and ulna, with the intervening interosseous membraneRadial side of the first metacarpal base; additional tendon slips varyAbducts and helps extend the thumb at the carpometacarpal jointPosterior interosseous nerve, commonly described with C7-C8 contributionsBranches of the posterior interosseous artery

Bones

Bones - Upper Limb Sheet. Every upper limb structure on one sheet - muscles, bones, nerves, vessels and the rest, each type in its own table with its own columns.
BoneBone typeKey landmarksArticulations
ClavicleAn atypical long bone, with a small or poorly defined marrow cavityMedial sternal end; lateral acromial end; inferior conoid tubercle and trapezoid line; groove for subclaviusManubrium at the sternoclavicular joint; scapular acromion at the acromioclavicular joint
HumerusA long bone with an expanded end at each jointProximal head and anatomical neck; greater and lesser tubercles with the bicipital groove between them; surgical neck; deltoid tuberosity and radial groove on the shaft; distal epicondyles, capitulum, trochlea and radial, coronoid and olecranon fossaeHead with the scapular glenoid; capitulum with the radial head; trochlea with the ulnar trochlear notch
LunateA short bone of the carpusRounded proximal surface for the radius; hollowed distal surface for the capitate; a separate hamate facet may be presentRadius, scaphoid, triquetrum and capitate; also the hamate when a medial distal facet is present

Nerves

Nerves - Upper Limb Sheet. Every upper limb structure on one sheet - muscles, bones, nerves, vessels and the rest, each type in its own table with its own columns.
NerveRoot valueCourseMotorSensory
Axillary nerveUsually C5-C6, carried through the posterior cordLeaves the axilla through the quadrangular space beside the posterior circumflex humeral vessels; branches wrap around the surgical neckDeltoid and teres minor musclesSkin near the inferior lateral deltoid through the superior lateral cutaneous nerve of the arm
Brachial plexusUsual maps: C5 - dorsal scapular; C5-C6 - suprascapular, subclavius, upper/lower subscapular and axillary; C5-C7 - lateral pectoral, musculocutaneous and long thoracic; C6-C8 - thoracodorsal; C8-T1 - medial pectoral, medial arm/forearm cutaneous and ulnar; C5-T1 - radial; median chiefly C6-T1 with variable C5. Segmental maps varyRoots between anterior and middle scalenes; trunks in the lower posterior triangle; divisions behind the clavicle; cords named around the second part of the axillary arteryMost shoulder and upper-limb muscles, including many scapular stabilizers. Trapezius receives its main motor supply through the accessory nerveMost upper-limb skin; the shoulder tip also receives C3-C4 supraclavicular nerves, and the axilla/adjacent medial arm receives intercostobrachial supply, usually T2
Long thoracic nerveUsually anterior rami C5-C7, branching near the roots of the brachial plexusPasses from the lower neck beneath the clavicle and down the lateral chest wall on superficial serratus anteriorSerratus anterior muscleNo defined cutaneous territory; its branches serve the muscle rather than a patch of skin

Vessels

Vessels - Upper Limb Sheet. Every upper limb structure on one sheet - muscles, bones, nerves, vessels and the rest, each type in its own table with its own columns.
VesselOriginCourseBranchesSuppliesDrains to
Axillary artery 1Continuation of the subclavian artery beyond the lateral edge of rib 1Across the axilla, passing deep to pectoralis minor; becomes brachial below teres majorUsual pattern: superior thoracic; thoracoacromial and lateral thoracic; subscapular and the two circumflex humeral arteries. Shared origins and other variants occurAxillary tissues, shoulder and nearby thoracic wall; its continuation supplies the rest of the limbnot recorded
Brachial artery 1Axillary artery continuing past the inferior border of teres majorDown the anterior-medial arm into the cubital fossa; usually divides near the radial neck, although a higher division can occurProfunda brachii, superior and inferior ulnar collateral arteries, muscular branches, then the terminal radial and ulnar arteriesArm tissues directly and through its branches; forearm and hand through the radial and ulnar continuationsnot recorded
Radial artery 1Usually branches from the brachial artery in the cubital fossaAlong the lateral forearm, over the snuffbox floor and between the heads of the first dorsal interosseous into the palmRadial recurrent, carpal and superficial palmar branches; first dorsal metacarpal, princeps pollicis and radialis indicis vessels, with continuation into the deep archParts of the forearm and wrist, deep palm, thumb and adjacent hand territories through communicating arterial networksnot recorded
