Answer 4

synovial, ball and socket

Question 5

Sternoclavicular joint synovial classification

Answer 5

synovial

Question 6

Scapulothoracic joint synovial classification

Answer 6

pseudo-joint necessary for full GH function

Question 7

Functions and attachments of the ligaments of the Sternoclavicular (SC) joint

Answer 7

• function: anterior and posterior SC ligaments restrict anterior and posterior translation of the clavicle on the manubrium - limit protraction and retraction as well
  • location: posterior and anterior articulating surfaces of clavicle and manubrium

Question 8

Functions and attachments of the ligaments of the Acromioclavicular (AC) joint

Answer 8

• AC ligament:
  
  • location: distal end of clavicle to acromion
• Coracoclavicular ligaments:
  
  • trapezoid ligament:
    - location: medial coracoid process to distal anterior clavicle
  • conoid ligament:
    - location: proximal coracoid process to medial posterior clavicle
• function: stabilize AC joint

Question 9

Functions and attachments of the ligaments of the Coracoacromial joint

Answer 9

• function: prevents superior displacement of the humeral head by forming coracoacromial arch
• attachments: lateral border of coracoid process to acromion

Question 10

Functions and attachments of the ligaments of the Coracohumeral joint

Answer 10

• function: reinforces superoanterior aspects of joint capsule
• attachments: base of coracoid process to anterior aspect greater tubercle

Question 11

Functions and attachments of the ligaments of the Costoclavicular joint

Answer 11

• function: stabilize SC joint, limiting elevation of clavicle
• attachment: superior aspect of cartilage of 1st rib to undersurface of the clavicle

Question 12

Functions and attachments of the ligaments of the Superior transverse scapular joint

Answer 12

• function: closes off suprascapular notch
• attachment: base of coracoid process to medial edge of scapular notch

Question 13

Functions and attachments of the ligaments of the Interclavicular ligament

Answer 13

• function: minimal support, but restricts depression of clavicle
• attachment: runs on top of manubrium and connects to anterior SC ligament

Question 14

Functions and attachments of the ligaments of the Glenoid capsule

Answer 14

• function: added stability to the GH joint
• attachment: circumference of glenoid cavity to neck of humerus

Question 15

Functions and attachments of the ligaments of the Glenohumeral joint (GH) joint

Answer 15

• function: stabilizes GH articulation
• attachment: upper part of medial margin of glenoid cavity to lesser tubercle and neck of humerus

Question 16

Locate the areas of skin associated with a single spinal segment/nerve (dermatome)​
