Organization of the Arm

Question 1

Separated into an anterior and posterior compartment by

Answer 1

medial and lateral intermuscular septa (septum)

Question 2

From the Axillary artery/vein arises

Answer 2

• the Brachial artery and vein

- the collaterals

Question 3

Radial and Axillary nerve are derived from the

Answer 3

Posterior Cord of the brachial Plexus

Question 4

Axillary nerve innervate

Answer 4

Deltoid and the teres minor

Question 5

Radial Nerve Innervates/recieves info from

Answer 5

the muscles of the posterior compartments of the arm and the forearm and receives sensory information from lateral forearm (lateral Antebrachial Cutaneous Nerve)

Question 6

Ulnar and Median Nerve innervate

Answer 6

nothing in the arm and only pass through to gain access through the forearm and hand

Question 7

Ulnar nerve is derived from

Answer 7

Medial Cord

Question 8

Median Nerve is formed from

Answer 8

both lateral and medial cords, both of which are anterior division structures

Question 9

2 prominent superficial veins in upper extremity

Answer 9

Cephalic and Basilic Vein

Question 10

Cephalic Vein Arises on

Answer 10

Dorsoradial surface of the hand and courses proximally along the radial surface of the forearm

Question 11

Cephalic Vein location

Answer 11

-the groove on the lateral side of the biceps brachii and the brachialis and finally passes between the deltoid and the pectoralis major where it empties into Axillary Vein

Question 12

Basilic Vein arises on

Answer 12

ulnar side of the hand, up the medial aspect of forearm, pierces brachial fascia at the junction between the middle and lower third of the arm and empties into the brachial vein

Question 15

Landmarks for muscle attachment for Ulna

Answer 15

1. Coronoid process
2. Ulnar Tuberosity
3. Olecranon Process

Question 16

Landmarks for muscle attachment for Scapula

Answer 16

1. Supra-and infraglenoid Tubercle

2. Coracoid Process
