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
