Joints of the Upper Limb

Question 1

Sternoclavicular: 
What bones (bone parts) make up the joint?
What is the structural type?
What functions are allowed?

Answer 1

• Between the sternum and the clavicle
  The clavicular notch of the manubrium and the sternal end of the clavicle (medial)
• Plane
• Gliding

Question 2

Acromio-clavicular
What bones (bone parts) make up the joint?
What is the structural type?
What functions are allowed

Answer 2

• Between the clavicle and the scapula
  The acromian of the scapula and the acromial end of the claviacle (lateral)
• Plane
• Gliding

Question 3

Glenohumeral (shoulder): 
What bones (bone parts) make up the joint?
What is the structural type?
What functions are allowed

Answer 3

• Between the glenoid cavity of the scapula and the head of the humerus
• Ball and Socket
• Flexion, extension, adduction, abduction - both medial and lateral

Question 4

Elbow: 
What bones (bone parts) make up the joint?
What is the structural type?
What functions are allowed

Answer 4

-between the radius ulna and humerus

The troclea comes together with the torclear notch of the ulna - humeroulnar

The capitulum comes together with the head of radius - humeroradial

-Hinge; allows motion in one plane

Question 5

Proximal Radiolulnar and Distal Radioulnar: 
What bones (bone parts) make up the joint?
What is the structural type?
What functions are allowed

Answer 5

• Between the radius and ulna

Proximal: between the head of the radius and the radial notch of the ulna (head held in place by the annular ligament)

Distal: between the head of the ulna and the ulnar notch of the distal end of the radius

-Pivot joints; allow for pronation and supination

Question 6

Wrist (radiocarpal): 
What bones (bone parts) make up the joint?
What is the structural type?
What functions are allowed

Answer 6

• Between the radius and two of the carpal bones (scaphoid and lunate)
• Condyloid joint
• Flexion, extension, adduction, abduction -> allows for circumduction

Question 7

Intercarpal: 
What bones (bone parts) make up the joint?
What is the structural type?
What functions are allowed

Answer 7

• betweenh adjecent carapal bones
• plane joints
• gliding; translation

Question 8

Carpometcarpal digits 2-5: 
What bones (bone parts) make up the joint?
What is the structural type?
What functions are allowed

Answer 8

• between carpal bones and the proximal end of the metacarpals
• plane
• gliding

Question 9

Carpometcarpal digits 1: 
What bones (bone parts) make up the joint?
What is the structural type?
What functions are allowed

Answer 9

• Between metacarpal one of the trapezium which is close to the thumb
• Saddle joint
• Adduction, abduction, circumduction OPPOSTION; allows you to pick up things

Question 10

What is the structural type?
What functions are allowed

Answer 11

• between the distal ends of the metacarpals and the proximal phalenx
• Condoloyid

Flexion, extension, adduction, abduction -> allows for circumduction

Question 12
