Flashcards in Upper Limb Arthrology, Joints, Ligs & Burs Deck (24):
1

The scapulothoracic movement in which there is a gliding motion with the scapula moving superiorly (like when shrugging shoulders)

elevation

2

The scapulothoracic movement in which there is a gliding motion with the scapula moving inferiorly (like opposite of shrugging shoulders)

depression

3

The scapulothoracic movement in which there is a gliding motion with the scapula moving towards the spine

retraction/adduction

4

The scapulothoracic movement in which there is a gliding motion with the scapula moving away from the spine

protraction/abduction

5

The scapulothoracic movement in which the glenoid fossa is the point of reference

rotation

6

The scapulothoracic movement in which the glenoid fossa moves superiorly (the inferior angle moves laterally)

upward/lateral rotation

7

The scapulothoracic movement in which the glenoid fossa moves inferiorly (the inferior angle moves medially)

downward/medial rotation

8

What's a general description of the sternoclavicular (S-C) joint? (i.e. what articulates and what kind of joint is it?)

-the sternal end of the clavicle articulates with the manubrium
-synovial saddle

9

What are the available movements of the sternoclavicular joint?

-superior/inferior glide
-anterior/posterior glide
-rotation around medial-lateral axis

10

If you were to tell someone to go FOOSH, what would you be telling them to do?

fall on an outstretched hand

11

Between the cavities of the sternoclavicular joint, there is a(n):

articular disc

12

What are the four ligaments of the sternoclavicular joint?

-anterior sternoclavicular ligament
-posterior sternoclavicular ligament
-interclavicular ligament
-costoclavicular ligament

13

What does the costoclavicular ligament connect and what excessive movements does it prevent?

-connects the inferior clavicle to the 1st rib
-prevents all excessive movements except inferior glide

14

What's a general description of the acromioclavicular (A-C) joint? (i.e. what articulates and what kind of joint is it?)

-the acromial end of the clavicle articulates with the acromion of the scapula
-synovial plane joint

15

What are the available movements of the acromioclavicular joint?

-anterior/posterior glide
-rotation (small movement)

16

What are the ligaments of the acromioclavicular joint and what, specifically, do they attach?

-acromioclavicular ligament attaches the clavicle to the acromion
-coracoacriomial ligament attaches the coracoid process to the acromion
-coracoclavicular ligament attaches the coracoid process to the clavicle

17

Describe the coracoacromial arch

it's an arch formed by the coracoid process, the coracoacromial ligament and the acromion

18

What's the largest bone in the upper limb?

the humerus

19

What's a general description of the glenohumeral (G-H) joint? (i.e. what articulates and what kind of joint is it?)

-the glenoid fossa of the scapula articulates with the head of the humerus
-synovial ball and socket joint

20

What are the available movements of the the glenohumeral (G-H) joint?

-abduction/adduction
-flexion-extension
-internal/external rotation
-circumduction
-scaption

21

What's the glenoid labrum and what does it do?

fibrocartilagenous ring that attaches to the glenoid fossa and deepens the joint

22

What are the points in our notes we need to know about the glenohumeral joint capsule?

-thin and loose
-weakest inferiorly (the axillary recess) -- which promotes more inferior dislocations of the head of the humerus
-there is a weak spot in the capsule anteriorly called the foramen of Weitbrecht (which promotes more anterior dislocations of head of humerus)

23

What are the ligaments of the the glenohumeral joint and what, specifically, do they attach?

-coracohumeral ligament attaches the coracoid process to the greater tubercle
-glenohumeral (capsular) ligaments

24

What are the bursae of the glenohumeral joint and where, specifically, are they located?

-subacromial bursa (between the acromion and the joint capsule)
-subdeltiod bursa (between the deltoid muscle and the joint capsule -- often connected with the subacromial bursa)
NOTE: subdeltiod and subacromial bursa are often used interchangeably
