Shoulder Girdle Flashcards
What are 3 things in the subacromial space region?
Long head biceps tendon
Supraspinatus tendon
Subacromial bursa
What type of joint is the Sternoclavicular ligament
Synovial
Diarthrosis
Multiaxial
Plane or saddle
What is not a true joint
Scapularthoracic joint
What type of joint is the glenohumeral
Synovial
Diarthrosis
Ball and socket
Multiaxial
what are the bones of the shoulder
scapula
clavicle
humerus
what articulates with the head of the humerus
glenoid cavity or fossa
what 3 muscles attach to the cocacoid process
pec minor
short head of biceps brachii
coracobrachialis
be able to label suprascapular/superior notch
what is the attachment point for the rotator cuff muscles
greater tubercle
what 3 muscles attach to the bicipital/intertubercular groove
pec major
lat dorsi
teres major
ALL 3 INTERNALLY/MEDIALLY ROTATE HUMERUS
accessory ligaments of sternoclavicular joint
articular disc
sternoclavicular ligament
interclavicular
costoclavicular
the only synovial joint that connects the upper extremity to the axial skeleton?
sternoclavicular
acromioclavicular joint type ? (4)
synovial
diarthrosis
plane
triaxial
what are the accessory ligaments for the acromioclavicular joint
fibrous capsule
acromioclavicular ligament
coracoclavicular ligament
coracoacromial ligament
movements of glenohumeral joint
elevation/depression
adduction/abduction
horizontal adduction/abduction
medial/lateral rotation
circumduction
what is the purpose of the glenoid labrum
deepens the cavity and increases surface of the joint for stability
movements of the acromioclavicular joint
elevation/depresson
abduction, adduction
upward/downward rotation
glenohumeral joint type
synovial
diarthrosis
ball and socket
multiaxial
accessory ligaments of the GH joint
coracohumeral
transverse humeral
superior, middle, inferior glenohumeral
what does the transverse humeral ligament do
holds the tendon of biceps in intertubercular groove
movements of scapulothoracic joint
sliding
protraction/retraction
elevation/depression
upward/downward rotation of glenoid fossa
5 functions of the scapulothoracic joint
1) increase shoulder ROM
2) maintain length-tension relationship w deltoid
3)provide GH stability
4) injury prevention through shock absorber
5) permits elevation of the body
what does the rotator cuff do
stabilize humeral head in cavity
what muscles do the suprascapular nerve innervate
infraspinatus
supraspinatus
what muscle does the axillary nerve innvervate
teres minor, deltoid
what 3 muscles attach to the greater tubercle
supraspinatus
infraspinatus
teres minor
what passes through the quadrangular space
axillary nerve
posterior circumflex humeral artery
