Cards in this deck (41)

  1. 1radius head, ulnar headopposites
  2. 2ulna anterior, posterioranterior base of ulna you have the trochlear notch, and posterior you have the olecranon process
    "trochlear notch of the olecranon process"
  3. 3radial tuberosity deltoid tuberosity ulnar tuberosityradial tuberosity- biceps TENDON on radius
    deltoid tuberosity- HUMERUS
    ulnar tuberosity- brachialis muscle, just below trochlear notch of olecranon process of ulna
  4. 4cords of snuffboxmedial is Extensor Pollicis Longus
    Lateral is Extensor Pollicis Brevis
  5. 5brachioradialis- SIDE. innervation is same as posterior superficial compartment, Radial N, so grouped with them. Handshake muscle.radial recurrent artery
    radial nerve
    flexes forearm---- neutral position
    originates laterla supracondylar ridge humerus!
  6. 6the dorsal tubercle of radiusPOSTERIOR (dorsal....)
    pulley for EPB tendon (which is super long)
    EBP- extend IP joint thumb
    RADIALLY deviate wrist
  7. 7extensor pollicis longusO: middle 1.3 of posterior ulna and IO
    I: base of distal phalanx of thumb
    A: extension of thumb at IP jt, radial deviation of wrist
    N: deep branch of radial nerve
    B: posterior interosseous artery
  8. 8posterior antebrachium innervation & supplysuperficial
    be3rqevjoqwnc
  9. 9tendon of brachioradialis originateslateral supracondylar ridge humerus just above Styloid process
  10. 10anterior brachium separated from posterior bydeep fascia
    a PROPER Conn Tissue
    DENSE (rather than loose)
    connects with periosteum--- to bone
  11. 11anterior brachiumbiceps
    brachialis
    coracobrach
    MUSCULOCUT N
    Brachial A
  12. 12posterior brachium3 heads of triceps- extensors
    anconeus and articularis cubiti
    brachial profunda
    Radial N
  13. 13Radial N cutaneousposterior arm, lower lateral arm, posterior forearm
  14. 14roots trunks divisions cords terminal nerve branches5 3 2 3 5
  15. 15radial nerve lateral brachiumswitched in antebrachium because flipped forearm
  16. 16Anterior brachium diagram- brachial A in front, median N in front muscylocut N in front.back: ulnar N, Radial N (ulnar medial to humerus)
  17. 17median nerve in brachiumdoes not innervate brachium
  18. 18coracobrachialis ispierced by musculocut N which becomes lat antebrach cut.
    is adductor
  19. 19brachialisworkhorse. flexes elbow no matter what position because it is attached to ulna
  20. 20short head bicepscoracoid of scapula
  21. 21bicipital aponeurosisfuses with deep fascia.
    ULNA.
    its the TENDON that supinates the forearm
    TENDON on radius
  22. 22long head bicepsbicipital groove, insert supraglenoid tubercle
  23. 23triceps medial headworkhorse of elbow extension
    sits above spiral groove
    brachial profunda, radial N
  24. 24anconeuslateral epicondyle-olecranon
    a weak elbow extensor
    poor length, cross sectional area
  25. 25articularis cubitia subset of the medial head of the triceps
    any time you extend the elbow joint it is active. Pulls on joint capsule to keep it out of the way.
    subset of the WORKHORSE (most posterior part of triceps)
  26. 26elbow flexionbrachialis, biceps
  27. 27elbow extension3 head triceps, anconeus
  28. 28BICEPS CROSSES 2 JOINTSlong head abducts externally rotated arm
  29. 29the brachial A in the arm has 4 main branchesprofunda brachii- which splits into anterior or radial collateral, and posterior or middle collateral
    nutrient
    superior ulnar collateral
    inferior ulnar collateral
  30. 30superior, inferior ulnar collateralposterior, anterior to elbow joint, respectively
  31. 31which comes off brachial artery first? radial or ulnar?anterior/radial collateral, and posterior collateral, which are radial (lateral side of elbow)
    followed by superior and inferior ulnar collateral
  32. 32brachium nerve supply musculocutaneouspierces coraco, emerges lateral anterbrachial cutaneous
    injury to high brachium: lose adduction of shoulder because coracobrachialis, but not ALL- lats, pect major
    lose all elbow flexors (biceps, brachialis)
    lose lateral forearm sensation!!!!
    injury to low brachium nearly at elbow: only sensory loss
  33. 33no innervation of brachium?median and ulnar N
  34. 34in upper brachium, Median nerve travels _____ to brachial artery in the _____ compartment. Ulnar travels_____ to it in the _______ compartment.lateral, anterior
    medial, anterior
  35. 35in lower brachium, Median nerve travels _____ to brachial artery in the _____ compartment. Ulnar travels_____ to it in the _______ compartment.medial, anterior
    medial, posterior
  36. 36brachium nerve supplyradial N- 3 cutaneous branches innervate arm
    lower lateral brach cut
    post brach cut
    post antebrachial cut
    innervates triceps, with brach prof
  37. 37radial N DIVIDES IN FRONT OF LATERAL EPICONDYLEright before it, it innervates brachioradialis and ECRL
  38. 38radial N DIVIDES IN FRONT OF LATERAL EPICONDYLEsuperficial and deep branches
  39. 39Radial N loss- high armlose elbow extension, have wrist drop- no wrist extensors (Ext digit, ECRL, EDmin, ECulnaris, E indicis, EPL, EPB, ABDPL)
  40. 40radial N loss almost elbow armwrist drop but elbow ext ok
  41. 41terminal superficial branch radial Nthumb/ fingers
