Deltoid
Supraspinatus
Infraspinatus
Teres Minor
Teres Major
Subscapularis

2

Which Scapulohumeral muscle is a multipennate muscle?

Deltoid Muscle

3

What are the names of the four muscles that make up the rotator cuff (Their tendons form a single tendon unit to form a "cuff" over the head of the Humerus)?

Supraspinatus
Infraspinatus
Teres Minor
Subscapularis

4

What are the functions of the rotator cuff?

-Help lift and rotate arm
-Stabilize Humeral head within glenoid cavity

5

Which of the Rotator cuff muscles are not a rotator?

Supraspinatus

6

What does the Coracoacromial ligament, ligament that connects to the Acromion and Coracoid process, prevent from happening?

Superior displacement of Humeral head from glenoid cavity

7

What separates the tendon from the coracoacromial ligament, acromion, and deltoid muscle?

Subacromial bursa

8

A patient who has painful abduction of the arm during the arc of 50-130 degrees may be suffering from what?

Subacromial bursitis
-Painful arc syndrome

9

What provides a passageway for vessels and nerves to reach the upper extremities from the trunk?

Axilla

10

What the is pyramidal space that lies inferior to the glenohumeral joint and superior to the axillary fascia at the junction of the arm and thorax called?

Axilla

11

The axilla has an apex, base, and four walls, what does the apex of the axilla allow?

Cervicoaxillary canal: between first rib, clavicle, and superior edge of subsacapularis allows passage of arteries, veins, lymphatics, and nerves to reach the arm

12

What artery begins at the lateral border of the 1st rib and is a continuation of the subclavian artery?

Axillary Artery

13

What will the Axillary become when it passes the inferior border of the teres major?

Brachial Artery

14

The axillary artery, axillary vein, and cords and branches of the brachial plexus associate proximally within a fascial sleeve called?

Axillary Sheath

15

What divides the Axillary artery into its 3 parts?

Tendon of Pectoralis minor

16

What is the name of the arterial branch that arises from the 1st part of the axillary artery?

Superior Thoracic Artery

17

How many branches come off the 2nd part of the Axillary Artery and give the name(s)?

Thoracoacromial Artery
Lateral Thoracic Artery

18

What are the names of the three branches that arise from the 3rd part of the Axillary Artery?

-Anterior Circumflex Humeral Artery
-Posterior Circumflex Humeral Artery
-Subscapular Artery

19

What forms the Axillary vein and where does it lie?

-Brachial vein and Basilic vein at inferior border of the teres major.
-Lies medial side of axillary artery

20

The Musculocutaneous nerve Provides what innervation?

-Flexor muscles of the arm
-Cutaneous: Lateral antebrachial cutaneous nerve

21

What are the names of the Radial Cutaneous nerve Branches?

-Inferior Lateral Brachial Cutaneous Nerve
-Posterior Brachial Cutaneous Nerve
-Posterior Antebrachial Cutaneous Nerve

22

What nerve wraps around the surgical neck of the Humerus and what accompanies this nerve?

Axillary Nerve
-Posterior Circumflex Humeral Artery

23

Which nerve wraps around the shaft of the Humerus and what accompanies this nerve?

Radial Nerve
-Deep Brachial Artery

24

The Quadrangular Space is a four-sided posterior axilla space formed by what?

-Superiorly: Inferior Border of Teres minor
-Inferiorly: Superior Border of Teres major
-Medially: Long Head of Triceps
-Laterally? Surgical neck of humerus

25

The Quadrangular Space transmits (contains) what?

-Axillary nerve
-Posterior Circuflex Humeral Artery
-Posterior Circumflex Humeral Vein

26
