Cards in this deck (22)
- 1What is another name for the medial border of the scapula?axillary
- 2What is another name for the lateral border of the scapula?vertebral
- 3What makes up the sternum?maubrium
body
xiphoid process - 4Where on the humerus is most common for fractures in older adults?the surgical neck
- 5What are the four joints that make up the shoulder?glenohumeral joint
acromioclavicular joint
sternoclavicular
scapulothoracic - 6What is the glenohumeral joint comprised of?glenoid fossa
glenoid labrum
humeral head - 7What is the glenoid labrum made out of?fibrocartilage
- 8What is the function of the glenoid labrum?acts as a suction cup around the humeral head to provide further stability and increase surface area
- 9What two muscles blend into the labrum?biceps and triceps
- 10What is the function of the AC joint?allows the scapula to rotate in three dimensions allowing for increased UE motion
- 11What are the motion of the AC joint?tipping
tilting
IR/ER - 12What are three types of acromian variances and what do they look like?Type 1: normal, flat
Type 2: curved down - dipping
Type 3: hooked and downward dipping - 13What is unique about the sternoclavicular joint?it is a synovial joint - has a disc that acts as a hinge during motion
- 14What type of joint is the scapulothoracic?pseudo joint
- 15Which ligament in the shoulder is the "problem child" and what does it do?coracoacromial ligament - attaches the coracoid process and acromion
- 16What structure encases the synovial fluid in the joint?joint capsule
- 17What is the bursae composed of?layers of synovial tissue with a thin layer of fluid between
- 18What is the purpose of the bursae?reduces friction to permit smooth gliding between structures
- 19What is the movement ratio for scapulohumeral motion?180 degrees total - GH 120 and ST provides 60
GH to scapula (2:1) - 200-30 degrees of scapulohumeral motionall GH joint
- 2130-90 degrees of scapulohumeral motion1:1 ratio of GH motion and scapula
- 2290-120 degrees of scapulohumeral motionGH 60; ST joint (AC kicks in the last 30 degrees of motion)
