Ligaments of upper limb

Question 1

Inferior acromioclavicular ligament

Answer 1

Inferior aspects of the acromion to the lateral aspect of clavicle

Question 2

Superior acromioclavicular ligament

Answer 2

Connects superior aspects of acromion to the lateral aspect of the clavicle.

Question 3

Annular ligament

Answer 3

Anterior margin of radial notch of ulna circling around the head of radius to attach to radial notch.

Question 4

Function of Coracoacromial ligament

Answer 4

Stabilizes and supports the humeral head and prevents superior dislocation.
Stabilizes coracoid process to a bigger structure to create more stability and strengthens coracoid.

Question 5

Coracoclavicular ligament connects

Answer 5

The upper surface of coracoid to the under surface of clavicle

Question 6

Two part of coracoclavicular ligament

Answer 6

Conoid: Conoid tubercle of clavicle to upper surface of coracoid process
Trapezoid: Trapezoid line on the inferior clavicle to upper surface of coracoid process of scapula

Question 7

What ligaments stabilize the sternoclavicular (SC) joint

Answer 7

Costoclavicular, sternoclavicular and interclavicular ligaments

Question 8

Coracohumeral ligament

Answer 8

Outer border of coracoid process and the greater tubercle of the humerus

Question 9

Function of the Coracohumeral ligament

Answer 9

Stabilizes GH joint. Prevents superior or inferior dislocation of the humeral head during external rotation.

Question 10

Costcoclavicular ligament

Answer 10

Inferior margin of sternal end of clavicle to the superior margin of the 1st rib and its costal cartilage.

Question 11

Transverse humeral

Answer 11

Greater tubercle to lesser tubercle.

Question 12

Sternoclavicular ligament

Answer 12

Anterior: Anterosuperior aspect of sternal end of clavicle to posterior aspect of manubrium.

Posterior: Posterior aspect of sternal end of clavicle to anterior aspect of manubrium and 1st costal cartilage

Question 13

Interclavicular

Answer 13

Sternal end of one clavicle to sternal end of the other clavicle

Question 14

Inferior glenohumeral

Answer 14

Inferior glenoid margin to inferior aspect of anatomical neck of humerus.

Question 15

Function of Inferior glenohumeral ligament

Answer 15

Question 18

Superior glenohumeral:

Answer 18

Supraglenoid tubercle to proximal tip of lesser tubercle

Question 19

Function of annular ligament

Answer 19

Holds head of radius against ulna to prevent distal dislocation of radius

Question 20

Radial collateral ligament (elbow)

Answer 20

Lateral epicondyle of humerus to annular ligament and proximal end of supinator crest of ulna

Question 21

Ulnar collateral ligament (elbow)

Answer 21

Medial epicondyle of humerus to proximal part of coronoid process and medial margin of olecranon of ulna
