adducts arm
teres minor function
externally rotates
two main joints of shoulder
acromiovlavicular
glenhumeral
brachial plexus includes nerve roots
c5-t1
injury caused by repetitive overhead activity causing pinching of rotator cuff under acromion
Impingement
which ligament is injured if person dislocates shoulder
acromioclavicular
“stinger” is stretching of what nerve plexus
brachial
lateral epicondylitis results from
repetitive extension of the wrist
inflamaton of glenhumeral joint (repetitve overhead movement of the shoulder)
subacromial bursitis
landing on the tip of shoulder
acromioclavicular seperation
which drection would humerous move when shoulder is forced into external rotation, causing dislocation
anterior to the shoulder (moved forward)
