supported by what only, this leads to what injuries?
what is like meniscus in knee and adds stability?
only by mms, leads to inf. and ant. dislocations
GH ligs provide support esp. where?
ligs are lax until extreme _____ is reached due to wide ROM involved.
____ is sacrificed to gain ____
anteriorly and inferiorly (inferior glenohumeral lig)
Stability sacrificed for mobility

Rotator cuff mms and their placement??
subscap is ant!
supra is sup!
infra is inf!
teres minor is post/inf!
rotator cuff mms attach to the front top and rear of ____ head.

rotator cuff mms are vital in mantiaining humeral head in correct approximation within ____ ____ while more powerful mms move ____ throughout its wide ROM.
What is GIRD?
overhead athletes with gird of greater than ___% had a higher risk for injury
____ exercises are recommended to regain internal rotation
Glenohumeral internal rotation deficit
diff internal rot rom between throwing and non throwing arms
what are the pairings of shoulder joint and shoulder girdle (scapular) movements?
ab with upward rotation
flexion with upward rotation and elevetion
interal rotation with abduction
horizontal add with abduction
GH is paired with ___ ___ to accomplish total shoulder ___
