Joints of upper limb

Question 1

The acromioclavicular joint is_____________?

Answer 1

• joint of acromion and clavicle
• diarthrotic with gliding and rotation
• Synovial joint, in a plane

Question 2

The glenohumeral joint___________?

Answer 2

• scapula and humerus
• synovial, ball and socket joint
• Diarthrotic with multiple axis

Question 3

The elbow is what type of joint?

Answer 3

• Consists of the ulna, humerus and indirectly the radius
• is a synovial hinge joint
• A diarthrotic uniaxial joint.

Question 4

The radioulnar joint consists of what section and is what type of joint?

Answer 4

• radius and ulna
• is a synovial pivot joint. radius pivots over the ulna
• A diarthrotic uniaxial joint

Question 5

Describe the sternoclavicular joint and its planes of movement.

Answer 5

• joint between sternum and clavicle
• A synovial joint with a shallow saddle
• Diarthrotic and multiaxial.
• considered double gliding joint as it has an inner and outer articular gliding surface

Question 6

Where is the intertubercular synovial sheath?

Answer 6

This sheath protects the long head tendon of the biceps, as it passes through the intertubercular groove on its way to attach to the superior glenoid tubercle.

Question 7

Where is the coraco humeral ligament?

Answer 7

This ligament attaches to the lateral lip of the intertubercular groove and attaches to the coracoid process of the scapula

Question 8

What is the glenohumeral ligament?

Answer 8

• has anterior and posterior divisions of the joint.
• Divided into the superior, middle, and inferior sections
• this is the ligament that is affected with a shoulder dislocation.

Question 9

The coracoclavicular joint connects what?

Answer 9

• composed of the trapezoid and conoid ligaments
• the trapezoid ligament is from coracoid to lateral aspect of clavicle
• the conoid ligament attaches from coracoid to just medial of the trapezoid ligament

Question 10

How many bursa are used in the shoulder and what are they?

Answer 10

• 4
• subscapular
• subdeltoid
• subcoracoid
• subacromial

Question 11

Subscapular bursa is located where?

Answer 11

-between the subscapular muscle and the joint capsule

Question 12

Where is the subdeltoid bursa located?

Answer 12

-located between the deltoid muscle and the joint capsule

Question 13

Where is the subcoracoid bursa?

Answer 13

-located between the subscapularis and the coracoid process

Question 14

Where is the subacromial bursa, and what is the it prone to as far as injury?

Answer 14

• Located under the acromion and on top of the supraspinatous which inserts on the greater glenoid tubercle.
• The location makes the bursa prone to inflammation and impingement as the humerus is raised repeatedly above the 90 degree mark
