any shoulder abduction above 90 degrees would hurt
what lig is on top of the scapular notch?
superior transverse scapular lig.
does artery or nerve pass above the superior scapular notch
artery above and nerve inside the notch
what's the name of the notch at the spine of the scapula
spinoglenoid notch
axillary and post circumflex humeral artery come out of where
quadrangular space
what come out of triangular space
circumflex scapular a
what forms the triangular space
the teres minor, major and long head of triceps
quadrangular space is bounded by what muscles
teres minor, teres maj, long head of tricep brachii, humerus
circumflex scapular a originate from what branch
the subscapular a
name the two notch on the scap
scapular notch and spinoglenoid notch
what lig on the scapula
superior transverse scapular lig
what pass under lig on scap
n under and a above
the axillary becomes what after going through the quadrangular space
it becomes post axillary n then become upper lateral brachial cutaneous n
what would happen to the dislocation of shoulder jt.
the quadrangular space would be compressed-> the axillary n will be compressed > loss of motor to teres minor and deltoid and sensory to deltoid and inability to abduct beyond 20 degrees
describe the anastomoses around the scap
formed by:transverse cervical artery, suprascapular artery, circumflex scapular branch (subscapular a) and post circum. humeral artery
where does suprascapular a originate from
from thyrocervical trunk of first part of subclavian a
where does transverse cervical artery and where does it go
it is from thyrocervical trunk and go to the medical border of scapular forming anastomosis with three other a.
what would happen to a patient who have suprascapular n that ndoesn't work
this patient can't initiate the first 20 degrees of arm abduction
what does radial n branch into and what muscle does it supply
lower lateral brachial cutaneous n and it supplies the triceps
tricep is supplied by what sensory n
lower lateral brachial cut. n
what n come out of T2 intercostal space where does it supply
intercostal brachial n. supply medial and post part of arm
what muscle is separated by the spiral groove
proximally by lateral head of triceps and distally by the med head of triceps
trace the path of radial n after it pass through the radial groove
it pass through the lateral intermuscular septum, pass behind the lateral epicondyle, change into superfical and deep branches of radial n.
it pass through the lat head of triceps through lat epicondyle to become the Posterior cutaneous n of forarm
profunda or deep brachial a give rise to what two branches
middle and radial collateral branches.
middle collateral branches anastomose with what?
interosseous recurrent a
radial collateral branch anastomose with what?
radial recurrent a
what tendons wrap around the glenohumeral jt
subscapularis, supraspinous, infrasp, and teres minor
radial n injury can be caused by
saturday night pulsy, use of crutch, may result in "wrist drop" because the ext muscles of middle of the posterior forarm are weak.
