Ans-
03.)
a) F – growing end of bone at upper end , fuses with shaft at 20 years
b) T – through radial head & ulnar styloid
c) T – deltoid & teres minor mainly , supplied by axillary nerve
d) T – between lateral 1/3 & medial 2/3 in between costoclavicular & coracoclavicular ligaments
e) F – none before birth
, 04. Regarding the brachial plexus
a) Suprascapular nerves originate from the upper trunk.
b) Divisions lie behind the subclavius.
c) Posterior cord supplies the muscles of the posterior compartment.
d) The cords of the brachial plexus lie lateral to the first part of the axillary artery.
e) Lower trunk is likely to damage when the neck is suddenly turned to the other side.
Ans-
04.)
a) T – also nerve to subclavius
b) T – behind middle 1/3 of clavicle
c) T – radial nerve
d) F – lateral & posterior cords superolateral . posterior cord posterior . 2nd part – each cord has
same relation as name of cord
e) F – upper trunk (Upper trunk damage leads to erb’s palsy)
05. Regarding the ulnar nerve
a) The adductor pollicis is supplied by the deep branch of the ulnar nerve.
b) In the ulnar nerve palsy holding a piece of paper between the index and the middle finger is
difficult.
c) Clawing is more profound if the ulnar nerve is damaged at the wrist than it is damaged at the
elbow.
d) Ulnar nerve lies posterior to the medial epicondyle.
e) Lies lateral to the ulnar artery.
f) If damaged sensory loss of the medial side of the forearm.
Ans-
05)
a) T
b) T – paralysis of interossei & lumbricals
c) T – clawing produced by unopposed action of finger extensors and of flexor digitorum profundus .
when nerve is damaged at elbow , ulnar half of flexor digitorum profundus is out of action & can’t
flex distal interphalangeal joints of ring & little fingers . clawing less profound when damaged at
elbow
d) T
e) F – medial ( two arteries are on outer aspect relative to nerves )
06. Regarding the mammary gland
