scapular region - specific points Flashcards
(15 cards)
what are the anastomosis present in the scapular region
- dorsal scapular + suprascapular
- dorsal scapular + thoracodorsal
- circumflex scapular + suprascapular
- circumflex scapular + dorsal scapular
what are the branches off the subclavian artery we need to know
- thyrocervical trunk
- dorsal scapular
what are the branches off the thyrocervical trunk artery
- transverse cervical artery
- suprascapular artery
what is unique about how the suprascapular nerve and artery pass by the scapular notch and transverse scapular ligament
the suprascpular nerve will travel through the notch while the artery passes above the transverse scapular ligament
what is in the subacrominal space
- supraspinatus muscle
- subacrominal bursa
where do we usually find burse
tendon and bone interaction
the subacrominal burse limits friction between what structures?
supraspinatus muscle
the subtendinous bursa of subscapularis limits friction between what
subscapularis tendon and coracoid process
the posterior circumflex humeral artery supplies what muscle?
deltoid ONLY
the axillary nerve innervates what muscles
deltoid and teres minor
what is the blood supply to the trapezius
transverse cervical artery
when the arm is in an adductued position what is the function of the long head of triceps brachii
holds the humerus within the glenoid cavity
the subacrominal bursa creates cushion between what structures
- acromion
- supraspinatus tendon
- coracoacromial ligament
- joint capsule
what ligaments stabilize the glenohumeral joint
- anteriorly: glenohumeral ligament
- superiorly: coracoacromial ligament
- inferior/posteriorly: joint capsule
what are the palpable regions of the back?
- acromion of scapula
-greater tubercle of humerus - medial border of scapula
- superior angle of scapula
- ribs
- iliac crest of ilium
- greater trochanter of femur
- ischial tuberosity
- sacrium
