Abductor digiti minimi (hand)
Pisiform, with attachment to the flexor carpi ulnaris tendon
Ulnar side of the fifth proximal phalanx at its base
Moves the fifth finger away from the ring finger
Deep ulnar nerve branch, mainly C8–T1
Muscular branches of the ulnar artery
Abductor pollicis brevis
Flexor retinaculum and the scaphoid and trapezium tubercles
Radial side of the thumb's proximal phalanx at its base
Produces palmar abduction of the thumb
Recurrent median nerve branch, mainly C8–T1
Radial artery, through its superficial palmar branch
Abductor pollicis longus
Back of the radius and ulna, with the intervening interosseous membrane
Radial side of the first metacarpal base; additional tendon slips vary
Abducts and helps extend the thumb at the carpometacarpal joint
Posterior interosseous nerve, commonly described with C7-C8 contributions
Branches 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.
Bone
Bone type
Key landmarks
Articulations
Clavicle
An atypical long bone, with a small or poorly defined marrow cavity
Medial sternal end; lateral acromial end; inferior conoid tubercle and trapezoid line; groove for subclavius
Manubrium at the sternoclavicular joint; scapular acromion at the acromioclavicular joint
Humerus
A long bone with an expanded end at each joint
Proximal 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 fossae
Head with the scapular glenoid; capitulum with the radial head; trochlea with the ulnar trochlear notch
Lunate
A short bone of the carpus
Rounded proximal surface for the radius; hollowed distal surface for the capitate; a separate hamate facet may be present
Radius, 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.
Nerve
Root value
Course
Motor
Sensory
Axillary nerve
Usually C5-C6, carried through the posterior cord
Leaves the axilla through the quadrangular space beside the posterior circumflex humeral vessels; branches wrap around the surgical neck
Deltoid and teres minor muscles
Skin near the inferior lateral deltoid through the superior lateral cutaneous nerve of the arm
Brachial plexus
Usual 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 vary
Roots between anterior and middle scalenes; trunks in the lower posterior triangle; divisions behind the clavicle; cords named around the second part of the axillary artery
Most shoulder and upper-limb muscles, including many scapular stabilizers. Trapezius receives its main motor supply through the accessory nerve
Most 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 nerve
Usually anterior rami C5-C7, branching near the roots of the brachial plexus
Passes from the lower neck beneath the clavicle and down the lateral chest wall on superficial serratus anterior
Serratus anterior muscle
No defined cutaneous territory; its branches serve the muscle rather than a patch of skin

Supplies
Drains to
Axillary artery 1
Continuation of the subclavian artery beyond the lateral edge of rib 1
Across the axilla, passing deep to pectoralis minor; becomes brachial below teres major
Usual pattern: superior thoracic; thoracoacromial and lateral thoracic; subscapular and the two circumflex humeral arteries. Shared origins and other variants occur
Axillary tissues, shoulder and nearby thoracic wall; its continuation supplies the rest of the limb
not recorded
Brachial artery 1
Axillary artery continuing past the inferior border of teres major
Down the anterior-medial arm into the cubital fossa; usually divides near the radial neck, although a higher division can occur
Profunda brachii, superior and inferior ulnar collateral arteries, muscular branches, then the terminal radial and ulnar arteries
Arm tissues directly and through its branches; forearm and hand through the radial and ulnar continuations
not recorded
Radial artery 1
Usually branches from the brachial artery in the cubital fossa
Along the lateral forearm, over the snuffbox floor and between the heads of the first dorsal interosseous into the palm
Radial recurrent, carpal and superficial palmar branches; first dorsal metacarpal, princeps pollicis and radialis indicis vessels, with continuation into the deep arch
Parts of the forearm and wrist, deep palm, thumb and adjacent hand territories through communicating arterial networks
not recorded

Function
Axillary lymph nodes 2,3,4
Within axillary fat, around regional vessels and toward the axillary apex
Pectoral, subscapular, humeral, central and apical groups; surgical levels I-III use a different grouping
not recorded
not recorded
not recorded
Apical efferent vessels form the subclavian trunk; it may join a major lymphatic duct or enter the veins directly near the neck root
Expose incoming lymph to immune cells and help filter material from regional tissues
