Unit 2 Shoulder Complex Joint And Ligaments

Front 1

JOINTS OF THE SHOULDER COMPLEX

Back 1

sternoclavicular, acromioclavicular, glenohumeral, and scapulothoracic

Front 2

SUBACROMIAL (SUBDELTOID) BURSA

Back 2

pads b/w the rotator cuff tendons and the humeral head

Front 3

STERNOCLAVICULAR JOINT

Back 3

articulation b/w sternum and clavicle, contain a small fibrous disk

Front 4

LIGAMENTS THAT SUPPORT THE STERNOCLAVICULAR JOINT

Back 4

sternoclavicular ligament, costoclavicular ligament, interclavicular ligament

Front 5

STERNOCLAVICULAR LIGAMENT

Back 5

connects the clavicle to the sternum on both anterior and posterior surfaces; reinforces joint capsule

Front 6

COSTOCLAVICULAR LIGAMENT

Back 6

connects the inferior surface of clavicle to the superior surface of the costal cartilage of rib 1; limits clavicular elevation

Front 7

INTERCLAVICULAR LIGAMENT

Back 7

connects the sternal ends of both clavicles across the superior aspect of the manubrium; limits clavicular depression

Front 8

ACROMIOCLAVICULAR JOINT

Back 8

articulation b/w the scapula and the clavicle

Front 9

LIGAMENTS THE SUPPORT THE ACROMIOCLAVICULAR JOINT

Back 9

acromioclavicular ligament, coracoclavicular ligament, coracoacromial ligament

Front 10

ACROMIOCLAVICULAR LIGAMENT

Back 10

connects the acromion to the clavicle; prevents the posterior dislocation of clavicle

Front 11

CORACOCLAVICULAR LIGAMENT

Back 11

connects the coracoid to the inferior clavicle; prevents posterior motion of the scapula and limits scapular upward rotation

Front 12

CORACOACROMIAL LIGAMENT

Back 12

connects two bony landmarks on the same bone: coracoids and acromion of the scapula; forms the coracoacromial arch to protect the rotator cuff tends and subacromial bursa from direct trauma from the acromion

Front 13

TWO PARTS OF THE CORACLAVICULAR LIGAMENT

Back 13

trapezoid, conoid

Front 14

SCAPULOTHORACIC JOINT

Back 14

articulation b/w scapula and rib cage

Front 15

SCAPULOHUMERAL RHYTHM

Back 15

relationship b/w scapulothoracic joint and glenohumeral joint; work together is a 2:1 ratio

Front 16

GLENOHUMERAL JOINT

Back 16

tri-axial, ball and socket, synovial; articulation b/w glenoid fossa and humeral head

Front 17

LIGAMENTS THAT SUPPORT THE GLENOHUMERAL JOINT

Back 17

coracohumeral ligament, glenohumeral ligament, glenoid labrum

Front 18

CORACOHUMARAL LIGAMENT

Back 18

connects the coracoids to greater tubercle

Front 19

GLENOHUMERAL LIGAMENT

Back 19

pleated folds in the anterior joint capsule in the superior, middle, and inferior directions; reinforces the joint capsule

Front 20

GLENOID LABRUM

Back 20

fibrocartilage that surrounds the rim of the glenoid fossa deepening the articular cavity
