Which is FALSE regarding the carpal tunnel,
p772,775 Moore p836,840NM
a.
Median nerve and flexor policis longus are superficial
T
b.
Flexor policis longus has it’s own sheath
T
c.
FDS and FDP tendons lie within the same sheath
at the tunnel
T
d.
FCR tendon may pierce the flexor retinaculum
T
e.
FCU lies within the canal of Guyon
F - it holds ulna art and nerve only
f.
tendon of FPL and median nerve lie in superficial
compartment
F
g.
eight flexor tendons share a common sheath
T - They sit in a common flexor sheath
h.
tendon of FPL and median nerve lie in superficial
compartment
F - No.Median n runs superficial and FPL below it
i.
eight flexor tendons share a common sheath
T - The tendons of FDS and FDP sit in a
common flexor sheath
.
j.
FPL in same sheath
F - As what? FPL is in its OWN sheath
k.
median nerve runs superiorly
T - superior to FPL
52.
Midpalmar space NMp829
a.
extends into lumbrical canals distally
T - Prob Yes
b.
is continuous with common carpal space
F – probably false
c.
extends proximally to the origin of FDS
F
d.
lumbrical tunnels
F - It runs above the lumbricals so don’t think so
e.
common synovial sheaths
? - It runs below the common synovial sheath (I think they mean common flexor
sheath) so don’t think so. BUT BLITZ HAS THIS ONE ie would have a fucking
clue
53.
The anatomical snuff box p780
a.
has trapezoid palpable at it’s base
F -No. Scaphoid and trapezium
b.
has EPL on it’s ulna side
T - (EPB and AbdPL on radial side)
c.
contains the posterior interosseus artery
F - No contains the radial artery
d.
lies between EPLand APL
T- yes but EPB is closer of the radial side
e.
is most obvious with the thumb abducted
F - No. Extended and abducted
f.
wrong tendons as boundary option
Anatomical snuff box bound by APL and EPB anteriorly and EPL posteriorly pg
749 Moore
g.
Branches of the radial nerve can be palpated over
the tendons
F – because you can’t actually feel it
h.
The cephalic vein begins in the roof
T - YES accord to LASTS p 68
i.
The bones palpable are the radial styloid, scaphoid,
trapezium and the base of the first metacarpal
T
j.
The tendons of abductor pollicis longus and extensor
pollicis longus form one boundary
F - APL and EPB form one boundary and the EPL forms the other
k.
On one side is extensor pollicis brevis and on the
other are EPL and APB.
F - EPB and APL on one side and EPL on the other
l.
A cutaneous branch of the radial nerve is palpable
in the snuffbox.
F - It lies in the roof but good luck if you can actually palpate it...
m.
Cephalic vein is in the floor
F – in the roof
n.
Radial artery is palpable in it floor
T
o.
Scaphoid, trapezium, 1
st
MC + radial styloid are palpable T
