Structure Relations of Scapular Region/Neurovascular Structures Flashcards
The posterior deltoid muscle is superficial to
the infraspinatus muscle
The axillary nerve and posterior circumflex humeral artery
run parallel to each other on the deep aspect of the deltoid muscle
The long head of the triceps brachii muscle
Passes in between the teres minor and teres major muscles
The teres minor muscle
is lateral to the infraspinatus muscle
The suprascapular artery passes
superior to the superior transverse scapular ligament
The suprascapular nerve
passes inferior to the superior transverse scapular ligament
The circumflex scapular artery passes
inferior and lateral to the teres minor muscle
TRIANGULAR SPACE
What space do the suparscapular nerve and suprascapular artery go through/by?
scapular notch
What bony landmark do the dorsal scapular nerve and artery go near?
medial border of the scapula
What artery goes through the triangular space?
circumflex scapular artery (inferior and lateral to the teres minor muscle)
What are the three borders of the triceps hiatus?
long head of triceps brachii, humerus, teres major
What neurovascular structures go through the triceps hiatus?
radial nerve, profunda brachii artery
What are the borders of the quadrangular space (scapula)?
long head of biceps brachii, teres minor, shaft of humerus, and teres major
What neurovascular structures go through the quadrangular space?
axillary nerve, posterior circumflex humeral artery
