Question 10

Classify the wrist joint

Answer 10

Condyloid, synovial

Question 11

Classify e elbow joint. What is the angle during maximum extension?

Answer 11

Hinge, synovial

170

Question 12

How many articulations in the elbow joint? Give them.

Answer 12

3
Humeroradial
Humeroulnar
Proximal radioulnar

Question 13

Describe specifically the articulations of the elbow.

Answer 13

Capitulum to radial head.
Trochlear to trochlear notch.
Radial head to radial notch.

Question 14

Give three ligaments in the elbow

Answer 14

Radial collateral
Ulnar collateral
Annular

Question 15

What does he radial collateral ligament in the elbow join? What is its function?

Answer 15

Lateral epicondyle to annular ligament around radial head.

Keeps the head of the radius in the capitulum.

Question 16

What does the ulnar collateral ligament join? Describe its structure.

Answer 16

3 parts:
Anterior is strongest spanning from med epicondyle to coronoid process.
Posterior is weaker fan like from med epicondyle to coronoid process.
Oblique deepens socket for medial epicondyle

Question 17

Describe the annular ligament.

Answer 17

Surrounds the lower head of radius.
Attached to the radial notch anteriorly and posteriorly.
Keeps the radial head close to the radial notch and joint tight.

Question 18

Give two bursae in the elbow and their location.

Answer 18

Subtendinous
- between triceps tendon and olecrannon.
Subcutaneous
- overlying olecrannon.

Question 19

What is dislocation and what is subluxation?

Answer 19

Dislocation is complete loss of contact of joint surfaces.

Subluxation is misalignment of joint surfaces but maintained articulation.

Question 20

Describe how adults ion of the medial epicondyle in the elbow occurs.

Answer 20

Severe abduction of extended arm.

Ulnar collateral ligament pulls medial epicondyle medially.

Question 21

Classify the glenohumeral joint.

Why is it unstable?

Answer 21

Ball and socket, synovial joint.

Disproportionate articulating surfaces, little area for articulation. Compromise in stability for mobility.

Question 22

Give the articulation of the glenohumeral joint.

Answer 22

Head of humerus to the glenoid cavity.

Lined with hyaline cartilage.

Question 23

How many ligaments in the glenohumeral joint

Answer 23

6
3 intra capsular
3 extra asphalt

Question 24

Describe the intra capsular ligaments of the glenohumeral joints.

Answer 24

Superior
Middle inferior
Thicken the capsule

Question 25

Give names of the 3 extra capsular ligaments of the glenohumeral joint and what the connect

Answer 25

Coracoacromial
Coracoid process to acromion
Coracohumeral
Coracoid process to greater tubercle
Transverse humeral
Overlies biceps tendon in biccipital groove

Question 26

Describe the coracoacromial arch

Answer 26

Coracoid process, acromion and coracoacromial ligament

Question 27

What is painful arc syndrome?

Answer 27

Pain on abducting from 50 to 130

Due to subscapularis tendon under CAA

Question 28

What does the subacromia bursa do?

Answer 28

Separate the coracoacromial ligament from the tendons of the rotator cuff muscles.
