Upper Limbs Short Questions

Hello. I was doing some short questions related to Upper Limb (my favourite yawww) when suddenly out came a brilliant idea off my head, which was to SHARE the knowledge with you all. But the rule is that I cant refer to the answers given until I finish doing all. Then, scratch the wrong answers and write down the real, correct, true answers in red. (huh, apa lagi..? paham tak. haha). 


Oh btw, its okey if you dont wanna read it. I don't mind at all. You may close the tab now. huhu.


Still reading this? wow, bagus2. Lets do it!


1. State 3 nerves closely related to humerus.
-Axillary nerve - surgical neck of humerus

-Ulnar nerve - posterior side of medial epicondyle


2. State the deformity resulting from injury of the following nerves.
-Radial nerve - wrist drop
-Ulnar nerve - ulnar claw hand
-Median Nerve - Ape-like hand
-Thoracic nerve - Winged scapula


3. State the clinical importances of brachial artery
-Blood pressure measurement
-Pulsation Brachial artery


4. State the clinical importance of radial artery and state where it can be felt.
radial artery's pulsation. It can be felt at the anterior lateral part of the wrist. 


5. State the contents of cubital fossa.

-brachial artery
-biceps tendon
-radial artery
should mention 'from medial to lateral'


6. State the branches of the lateral cord
-lateral side root of median nerve
-musculocutaneous nerve
-lateral pectoral nerve.


7. State the branches of medial cord

-median pectoral nerve
-median cutaneous nerve of arm
-median cutaneous nerve of forearm


8. State the branches of the posterior cord.
-subscapular nerve (upper and lower).
-thoracodorsal nerve
-axillary nerve
-radial nerve


9. State the boundaries of quadrangular space and state the structures that pass through it.
-bicipital aponeurosis 
-brachial artery and mean cubital nerve.
-teres minor, subscapularis, long head of triceps and surgical neck of humerus.
-axillary nerve and posterior circumflex humeral artery


10. State the muscles of the forearm involved if the ulnar nerve is injured at the elbow.
-flexor carpi ulnaris
-medial half of flexor digitorum profundus


11. State the intrinsic muscles of the hand involved if the ulnar nerve injured at the wrist.
-3rd and 4th lumbricals
-4 dorsal interossei
-4 palmar interossei
-adductor pollicis
-hypothenar muscles


10. State the muscles of the forearm involved if the median nerve injured at the elbow.
-flexor carpi radialis
-flexor pollicis longus.
-lateral half of flexor digitorum profundus


11. State the intrinsic muscles of the hand involved if the median nerve is injured at the wrist.
