The upper limb regions. Arteries of the upper limb: topography,

The surgeon exposes the axillary neurovascular bundle with an incision along the anterior border of the axillary region. In this case the first anatomical formation which he will see is

• axillary artery

• axillary vein

• axillary nerve

• brachial plexus

• ulnar nerve

In the shoulder area there are two fascial beds of the following

• side

• posterior

•  lateral

• anterior

• medial

Answer explanation

A patient with a fracture of the humerus at the level of the surgical neck has an extensive hematoma in the area of the fracture, most likely as a result of damage

• artery supplying humerus

• deep artery of arm

• posterior artery, circumflex of humerus

• brachial artery

• axillary artery

Indicate which two main arteries anastomose with each other through the scapular arterial circle

• subclavian artery (a. subclavia)

• brachial artery (a. brachialis)

• axillary artery (a.axillaris)

• brachiocephalic trunk (tr. brachiocephalicus)

• vertebral artery (a.vertebralis)

Musculocutaneous nerve innervates the muscles of

• anterior forearm

• anterior arm

• posterior arm

• posterior forearm

• hand

Name the branch of the axillary artery in the pectoral triangle:

• a. thoracica superior

• a. thoracoacromialis

Cephalic vein flows into

• brachial vein

• axillary vein

• subclavian vein

• external jugular vein

• cephalic vein

Branch of brachial artery

• superficial palmar branch

• deep artery of arm

• interosseous artery

• subscapular artery

• recurrent radial artery

What nerve can be damaged in a fracture of the surgical neck of humerus (collum chirurgicum)?

• ulnar nerve (n. ulnaris)

• vradial nerve (n. radialis)

• median nerve (n. medianus)

• axillary nerve (n. axillaris)

• subcostal nerve (n. subcostalis)

Name the branch of the axillary artery in the clavipectoral triangle:
