Ulna digital nerve supply p78 LASTS (Moore page 782, 783, 774)
a.
digital nerve branches lie superficial to the superficial
palmar arch
F - No they lie deep to it.
b.
digital nerve lies dorsal to the digital nerve along
the fingers
T
c.
common digital nerves lie superficial to superficial arch F
d.
palmar nerves only supply palmar surface
F
e.
digital nerves are only sensory.
T
f.
digital nerve lie posterior to digital artery
F - NO. it is NAV palmar to dorsal
13.
Dorsal scapular nerve
a.
Supplies deep part of rhomboids
T - pg 695 Moore (and levator scapulae)
b.
Branch of cervical plexus – C4
F - (kinda true but not best answer – arises chiefly from post aspect of ventral
ramus C5 with frequent contribution from C4) pg 708-moore
14.
What is supplied by PIN
(continuation of deep branch of radial nerve)?
a.
Extensor carpi radialis longs
F– radial nerve branch above elbow, before PIN given off pg 99 lasts, pg 742
Moore
b.
Anconeus
F – radial nerve branch that leaves trunk in radial groove)
c.
Extensor carpi ulnaris
T
15.
Which nerve does not pass through the muscle shown
a.
radial nerve and brachiradialis
F - doesn’t go through. It runs btwn brachialis and brachioradialis
b.
posterior interosseous nerve and supinator
T - It does
c.
musculocutaneous and coracobrachials
T - It does
d.
ulna nerve and FDS
F - it passes through FCU
e.
median nerve and pronator teres
T - Yes.
16.
Regarding the cutaneous nerve supply to arm and f
orearm (moore 682)
a.
C3/4 supply pectoral and upper shoulder
F - No. C3/C4 supply the neck. The pec is supplied by T1-T5
b.
Branches of the brachial plexus supply arm and forearm T
c.
C4/5/6 T1 supply the majority of the arm
F - Not really. C7 and C8 supply a lot
17.
Which is true concerning digital nerves?
a.
arteries are superficial to them on the palm of the hand F - No NAV from palmar to dorsal
b.
they are purely sensory
T
18.
Which mucle is supplied by the posterior interosseous nerve
in the cubital fossa p742
a.
Extensor carpi radialis longus
F - No radial n
b.
Anconeus
F - No radial n
c.
Extensor carpi radialis brevis
F - ?radial n
d.
Extensor digitorum
T - Yes but ?in cubital fossa
e.
Supinator
F - By deep branch of radial n accord to Moore BUT by PIN accord to
