Question 7

medial and lateral pectoral nerves injury?

Answer 7

pectoralis major muscle paralysis~difficult to move the arms towards each other

pronounced areolar asymmetry due to atrophy of pectoralis major muscle

Question 8

pectoralis minor orgin
insertion
action
nerve supply

Answer 8

3;4;5 ribs
insertin coracoid process of scapula

depression of shoulser
if the shoulder fixed the ribs pushed towards the shoulder forced inspiration

medial pecctoral nerve C8;T1

Question 9

SUBCLAVIUS MUSCLE OORGIN
insertion
action
nerve supply

Answer 9

1st rib at the costachondral junction
bottom surfaceof middle part of the clavicle ;subclavian groove
depress the shoulder
when the clavicle is fixed it elevates the 1st rib
nerve to subclavius from upper trunk of B P C5 C6

long head from supraglenoid tubercle of scapula

radial tuberosity

flexion of arm and forearm
powerful supination of partially flexed forearm

musculocutaneous nerve C5-C7

Question 13

Question 15

the repture of transverse humeral ligament ?

Answer 15

casuing the shealth to slid back and forth leading to a wear and tear effect on the long head of biceps tendon

erpetitive microtrauma can also lead to inflammation of the tendon

of brachialis muscle

Answer 19

distal half of the anterior humerus
coronoid process of ulna
ulnar tuberosity

Question 20

coracobrachialis orgin
insertion
action
nerve supply

Answer 20

coracoid prosess of scapula
mid part of medial surface of the humerus
flexes;adducts and medially rotates the arm
musclocutaneous nerve c5-C7

superior ulnar cllateral art
inferior ulnar art
ulnar art
radial art

Question 28

profunda deep brachial artery?
divides into 2 branches

Answer 28
