Pectoral Region Outcomes

Question 1

What are the joints of the shoulder girdle?

Answer 1

A. Sternoclavicular
B.Acromioclavicular
C. Glenohumeral
D. Scapulothoracic

Question 2

What is the synovial classification of the sternoclavicular joint?

Answer 2

Saddle

Question 3

What is the synovial classification of the acromioclavicular joint?

Answer 3

Plane

Question 4

What is the synovial classification of the glenohumeral joint?

Answer 4

Ball & socket

Question 5

What is the synovial classification of the scapulothoracic joint?

Answer 5

pseudo-joint- it does not have ligaments, true joint surfaces, cartilege

Question 6

What is the purpose of the scapulothoracic joint?

Answer 6

This pseudo-joint functions to allow the scapula to move with the upper limb to allow full glenohumeral function

Question 7

What does the coracoclavicular ligament do?

Answer 7

Stabilizes acromioclavicular joint & limits medial displacement, protraction, & elevation
-trapezoid
-conoid

Question 8

What are the two “sub”-ligaments of the coracoclavicular ligament of the AC joint?

Answer 8

Trapezoid (lateral): attaches from coracoid process to trapezoid line of clavicle
Conoid (medial): attached from coracoid process to conoid tubercle of clavicle

Question 9

Describe the acromioclavicular ligament?

Answer 9

The AC ligament stabilizes the AC joint
Attaches from superior aspect of acromical end of clavicle to adjacent acromion

Question 10

Coracoacromial ligament function and attachments?

Answer 10

Prevents superior displacement of the humeral head by forming the coracoacromial arch
Attaches from lateral border of coracoid process to acromion adjacent to clavicular articulation

Question 11

Coracohumeral ligament function and attachments?

Answer 11

Reinforces superoanterior aspects of the joint capsule
Attaches from base of coracoid process to anterior aspect greater tubercle

Question 12

Costoclavicular ligament function and attachment

Answer 12

This ligament functions to stabilize the sternoclavicular joint and limit elevation of the clavicle
Superior aspect of cartilage of 1st rib to undersurface clavicle

Question 13

Superior transverse scapular ligament

Answer 13

Closes of the suprascapular notch
Attaches from base of coracoid process to medial edge of scapular notch

Question 14

What neurovascular structures are near the superior transverse scapular ligament?

Answer 14

Superior to the ligament is the suprascapular artery
Inferior to the ligament and running inside the notch is the suprascapular nerve.

Question 15

What are the attachments of the glenoid capsule ligament?

Answer 15

Circumfrence of the glenoid cavity to the medial edge of the scapular notch

Question 16

Name the 3 glenohumeral ligaments, their function, and attachments?

Answer 16

1. Superior GH lig
2. Middle GH lig
3. Inferior GH lig
   The GH ligaments function to stabilize the GH articulation
   Attach at upper part of medial margin of glenoid cavity to lesser tubercle & anatomical neck
