Brachium: 07
Flashcards do conjunto (41)
- 1radius head, ulnar headopposites
- 2ulna anterior, posterioranterior base of ulna you have the trochlear notch, and posterior you have the olecranon process
"trochlear notch of the olecranon process" - 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 - 4cords of snuffboxmedial is Extensor Pollicis Longus
Lateral is Extensor Pollicis Brevis - 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! - 6the dorsal tubercle of radiusPOSTERIOR (dorsal....)
pulley for EPB tendon (which is super long)
EBP- extend IP joint thumb
RADIALLY deviate wrist - 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 - 8posterior antebrachium innervation & supplysuperficial
be3rqevjoqwnc - 9tendon of brachioradialis originateslateral supracondylar ridge humerus just above Styloid process
- 10anterior brachium separated from posterior bydeep fascia
a PROPER Conn Tissue
DENSE (rather than loose)
connects with periosteum--- to bone - 11anterior brachiumbiceps
brachialis
coracobrach
MUSCULOCUT N
Brachial A - 12posterior brachium3 heads of triceps- extensors
anconeus and articularis cubiti
brachial profunda
Radial N - 13Radial N cutaneousposterior arm, lower lateral arm, posterior forearm
- 14roots trunks divisions cords terminal nerve branches5 3 2 3 5
- 15radial nerve lateral brachiumswitched in antebrachium because flipped forearm
- 16Anterior brachium diagram- brachial A in front, median N in front muscylocut N in front.back: ulnar N, Radial N (ulnar medial to humerus)
- 17median nerve in brachiumdoes not innervate brachium
- 18coracobrachialis ispierced by musculocut N which becomes lat antebrach cut.
is adductor - 19brachialisworkhorse. flexes elbow no matter what position because it is attached to ulna
- 20short head bicepscoracoid of scapula
- 21bicipital aponeurosisfuses with deep fascia.
ULNA.
its the TENDON that supinates the forearm
TENDON on radius - 22long head bicepsbicipital groove, insert supraglenoid tubercle
- 23triceps medial headworkhorse of elbow extension
sits above spiral groove
brachial profunda, radial N - 24anconeuslateral epicondyle-olecranon
a weak elbow extensor
poor length, cross sectional area - 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) - 26elbow flexionbrachialis, biceps
- 27elbow extension3 head triceps, anconeus
- 28BICEPS CROSSES 2 JOINTSlong head abducts externally rotated arm
- 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 - 30superior, inferior ulnar collateralposterior, anterior to elbow joint, respectively
- 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 - 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 - 33no innervation of brachium?median and ulnar N
- 34in upper brachium, Median nerve travels _____ to brachial artery in the _____ compartment. Ulnar travels_____ to it in the _______ compartment.lateral, anterior
medial, anterior - 35in lower brachium, Median nerve travels _____ to brachial artery in the _____ compartment. Ulnar travels_____ to it in the _______ compartment.medial, anterior
medial, posterior - 36brachium nerve supplyradial N- 3 cutaneous branches innervate arm
lower lateral brach cut
post brach cut
post antebrachial cut
innervates triceps, with brach prof - 37radial N DIVIDES IN FRONT OF LATERAL EPICONDYLEright before it, it innervates brachioradialis and ECRL
- 38radial N DIVIDES IN FRONT OF LATERAL EPICONDYLEsuperficial and deep branches
- 39Radial N loss- high armlose elbow extension, have wrist drop- no wrist extensors (Ext digit, ECRL, EDmin, ECulnaris, E indicis, EPL, EPB, ABDPL)
- 40radial N loss almost elbow armwrist drop but elbow ext ok
- 41terminal superficial branch radial Nthumb/ fingers
