Q

the repture of transverse humeral ligament ?

A

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

when abiceps tendon ruptures ;the muscle belly changes position in the arm

A

popeye’s sign

18
Q

action of brachialis muscle ?

A

powerful and the main flexor of forearm

19
Q

orgin
insertion
nerve supply
of brachialis muscle

A

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

20
Q

coracobrachialis orgin
insertion
action
nerve supply

A

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

21
Q

musclocutaneous nerve runs through which muscle?

A

coracobrachialis muscle

22
Q

musclocutaneous nerve from ?

A

lateral cord of the brachial pelexus

23
Q

causes of musclocutaneous nerve?

A

compression
overuse
strenuous activity
trauma
surgery

24
Q

clinical features of musculocutaneous nerve ?

A

Reduced function of flexion and supination of forearm

skin sensory loss of anterolateral aspect of forearm

25
the artery that supplies the arm ;elbow;forearm and hand ?
bracial artery
26
//////after it passes the teres major muscle it forms the bracial artery
the axillary artery
27
branches of brachoal artery?
profunda deep bracial art superior ulnar cllateral art inferior ulnar art ulnar art radial art
28
profunda deep brachial artery? divides into 2 branches
radial cllateral =anterior descanding branch middle collateral =posterior descending branvh
29
brachial artery branches ???????????
superior ulnar collateral artery inferior ulnar collateral artery
30
both brachial artery and profunda brachii give important branches that form ///////
elbow anastomoses
31
supracondylar fracture of humerus ?
brachial artery median nerve
32
medial epicondyle fracture?
ulner nerve
33
muscle can stand ischmia for ///////after that they will///////
6 h undergo necrosis
34
[  ] Shortage  of oxygen required causing tissue damage or dysfunction
ischmia
35
veins anatomical
blood flow from periphery to the heart lowe oxygen branches downwards
36
arteries antomical
blood flow from the heart to the periphery with high oxygen branches upwards
37
superficial veins located in the///////
superficial fascia /subcutaneous tissue
38
drain the superficial regions of the arm
cephalic vein/lateral basilic vein/medial
39
basilic vein 3 p!!!
at lower 1/3 of the arm dives deep it perforates the deep fascia units with the brachial vein to form the axillary vein
40
anastomosis between the deep and the superficial veins /////
perforating
41
between two veins there is ///
one artery
