exam #3 Flashcards
at the glenohumeral joint, what must be sacrificed for the large range of motion
bone stability
ligament that connects clavicle to acromion
acromioclavicular
purpose of labrum
stabilize glenohumeral joint
which joint is associated with pronation and supination
all radio-humeral
which ligament holds the radius in place with respect to the humerus
radial collateral
where is the triangular fibrocartilage complex located
between ulna and carpal bones
which of the following joints do not have collateral ligaments
metacarpophalangeal
what prevents IP joint extension
volar plate
during pronation, which bone crosses which?
radius crosses ulna
abduction and adduction of the fingers 2-5 is with respect to what landmark
3rd finger
in order to achieve full shoulder abduction, what joints must move to accomplish that?
glenohumeral and scapulothoracic
list all the joints associated with what we generally call the shoulder joint
sternoclavicular, glenohumeral, scapulothoracic, acromioclavicular, coracoclavicular
describe what purpose the annular pulleys have
keep tendons from “bow stringing,” which would cause a loss of range of motion
list the structures involved in impingement syndrome
