22
Q

xiphoid process

A

meanning ‘sword shaped’, the inferior tip of the sturnum

23
Q

sternoclavicular joint

A

(SC) formed by the articulation between the manubrium of the sternum and the medial (sternal) end of the clavicle, triaxial joint, basically theclavicle moves as the sternum remains stationary, a synovial joint

24
Q

sternoclavicular ligament

A

connects the clavicle to the sternum on both the anterior and posterior surfaces and is therefore divided divided into the anterior and posterior sternoclavicular ligaments

25
Q

costoclavicular ligament

A

a short, flat, thromboid shaped ligament that connects the clavicle’s inferior surface to the superior surfaces of the costal cartilage of the first rib

26
Q

interclavicular ligament

A

located on top of the manubrium, connecting the superior sternal ends of the claicles

27
Q

acromioclavicular joint

A

(AC) connects the accromium process to the scapula and the lateral (acromial) end of the clavicle, is a plane -shaped synovial joint that allows a gliding acromioclavicular motion to occur

28
Q

coracoclavicular ligament

A

not directly located at the joint, does provide stability to that joint and allows the scapula to be suspended form the clavicle

29
Q

coracromial ligament

A

does not actually cross the AC joint however, forms a roof over the head of the humerus and serves as a protective arch and serves as a protective arch, providing support to the head when an upward force is transmitted along the humerus.

30
Q

scapulothoracic articulation

A

not a joint in the pure sense, there is no direct union between the bones and there is no joint capsule. Consists of a slightly concave anterior surface of the scapula resting on a convex posterior aspect of the rib cage

31
Q

scapular elevation

A

occurs when the scapula moves in a superior direction

32
Q

scapular depressio

A

occurs when the scapula moves inferiorly

33
Q

scapular protraction

A

occurs when the scapula moves away from the posterior midline

34
Q

scapula retraction

A

occurs when the scapula moves back toward the inferior posterior midline

35
Q

scapular upward rotation

A

inferior angle of scapula rotates up and away from the vertebral column

36
Q

scapular downward rotation

A

the return to the resting position from the upwardly rotated position

37
Q

scapular tilt

A

occurs when the shoulder joint goes into hyperextension. The superior end of the scapular tilts anteriorly while the inferior end tilts posteriorly

38
Q

scapular winging

A

the posterior lateral movement of the vertebral border of the scapula in the transverse plane

39
Q

shoulder joint flexion

A

shoulder girdle upward rotation, protraction

40
Q

shoulder joint extension

A

shoulder girdle downward rotation, retraction

41
Q

Shoulder joint hyperextension

A

shoulder girdle scapular tilt

42
Q

shoulder joint abduction

A

shoulder girdle upward rotation

43
Q

shoulder joint adduction

A

r girdle downward rotation

44
Q

shoulder joint medial rotation

A

shoulder girdle joint protraction

45
Q

shoulder joint lateral rotation

A

shoulder girdle joint retraction

46
Q

shoulder joint horizontal abduction

A

shoulder joint girdle retraction

47
Q

shoulder joint horizontal adduction

A

shoulder joint girdle protraction

48
Q

scapulohumeral rythm

A

concept that further describes the movement relationships between the shoulder girdle and the shoulder joint. The first 30 degrees of shoulder joint movement is pure shoulder joint motion. However, after 30 degrees, for every 2 degrees the shoulder flexion, or abduction occur, the scapula must upwardly rotate 1 degree, therefore a 2:1 ratio

49
Q

muscles of the shoulder girdle

A

Trapezius, levator scapula, rhomboids, serratus anterior, pectoralis minor

50
Q

acromioclavicular serapation

A

commonly used to describe the various amounts of ligament injury at the AC joint. In a first degree sprain, the acromioclavicular ligament is stretched. In the second degree the acromioclavicular ligament is ruptured and the coracoclavicular ligament is stretched. In a third degree sprain, both the acromioclavicular and the coracoclavicular ligaments are ruptured.

51
Q

Clavicular fractures

A

most frequent broken bone in children.

52
Q

shoulder girdle

A

has both linear and angular motions

53
Q

inferior angle

A

point of reference for scapular rotation

54
Q

scapulohueral rythm

A

shoulder girdle and shoulder combined motions
