Axillary Anatomy

Question 1

R. and L. Subclavian Arteries

Answer 1

Arteries running from the superior thoracic cavity under the clavicle to the teres major

Question 2

R. and L. Axillary Arteries

Answer 2

Surrounded by the brachial arteries distally and the subclavian arteries proximally.

Question 3

R. and L. Brachial Arteries

Answer 3

Axillary arteries become these more distally in the arm

Question 4

R. and L. Subclavian Veins

Answer 4

Veins located under the clavicle

Question 5

R. and L. Axillary Veins

Answer 5

Veins located in the axillary region

Question 6

R. and L. Deltoid Muscles

Answer 6

Most superficial muscles of the shoulder

Question 7

R. and L. Pectoralis Minor Muscles

Answer 7

Muscles more deep to the pectoralis major and superficial to the ribs and intercostals.

Question 8

R. and L. Anterior Scalene Muscles

Answer 8

Muscles that connect the transverse processes of the cervical vertebrae to the posterior first rib

Question 9

R. and L. Middle Scalene Muscles

Answer 9

Connect the transverse processes of the cervical vertebrae to the middle portion of the first posterior rib

Question 10

R. and L. Coracobrachialis Muscle

Answer 10

Connects the coracoid process of the scapula to the middle medial portion of the humerus. Assists in flexion.

Question 11

R. and L. Lateral Cords

Answer 11

lateral to the axillary artery, splits into the musculocutaneous nerve(innervates coracobrachialis) and the median nerve.

Question 12

R. and L. Medial Cords

Answer 12

Located medially to the axillary artery, branches into the ulnar nerve and the median nerve.

Question 13

R. and L. radial nerves

Answer 13

Branch off of the posterior cord, runs posterior to the axillary artery down the lateral side of the arm.

Question 14

R. and L. Ulnar Nerves

Answer 14

Branch off of the medial cord. Runs down the medial portion of the arm.

Question 15

R. and L. Axillary Nerves

Answer 15

Branch off of the posterior cord that goes to the axillary region.

Question 16

R. and L. Median Nerves

Answer 16

branch off of both the medial and lateral cords. Runs down the middle portion of the arm through the carpal tunnel. Innervates the lateral palm.

Question 17

R. and L. Musculocutaneous nerves

Answer 17

Branch off of the lateral cord of the brachial plexus. Innervates the coracobrachialis.

Question 18

R. and L. medial cutaneous nerves

Answer 18

Small, thin nerve branching off of the medial cord. Innervates the sensation of the medial aspect of the arm.

Question 19

R. and L. Posterior Cords

Answer 19

Splits into the radial nerve (runs down radius) axillary nerve (inserts shortly after)
