Final Flashcards
the pectoral/shoulder girdle is formed by
clavicles and scapulae
glenoid fossa is most what directed
laterally (anterior bias)
physiologic joint (scapulothoracic joint) produces what
produces motion, increases gh joint motion, increases rom of the shoulder girdle
axioscapular muscles do what main three things
connect scapula to the head or trunk, stabilize the scapula, move the scapula
what types of motions can the scapula do
elevation, abduction protraction, adduction retraction, depression
humeral head globular ancranom
sits
force couple is what
two or muscles work together to produce a movement
glenoid fosssa upward rotation results in
glenoid fossa facing superiorly
downward rotation of the glenoid fossa results in
glenoid fossa facing inferiorly
movements of the glenohumeral
abduction, adduction, flexion, extension, lateral rotation, medial rotation, scaption
acronym sits
supraspinatus, infraspinatus, teres minor, subscapularis
rotator cuff role
support the head of the humerus in the glenoid fossa
pa of the supraspinatus
supraspinous fossa of scapula
distal attachment of the supraspinatus
superior facet on greater tubercle of humerus
nerve of the supraspinatus
suprascapular nerve
action of the supraspinatus
initiates and assists deltoid in abduction of gh joint
pa of infraspinatus
infraspinous fossa of scapula
distal attachment of infraspinatus
middle facet on greater tuberosity of humerus
nerve of infraspinatus
suprascapular nerve
action of infraspinatus
laterally rotate gh joint
pa of teres minor
superior part of lateral border of scapula
distal attachment of teres minor
inferior facet on greater tuberosity of humerus
nerve of teres minor
axillary nerve
action of teres minor
laterally rotate gh joint
