Q

xiphoid process

Study These Flashcards
A

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

23
Q

sternoclavicular joint

Study These Flashcards
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

Study These Flashcards
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
costoclavicular ligament
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
interclavicular ligament
located on top of the manubrium, connecting the superior sternal ends of the claicles
27
acromioclavicular joint
(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
coracoclavicular ligament
not directly located at the joint, does provide stability to that joint and allows the scapula to be suspended form the clavicle
29
coracromial ligament
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
scapulothoracic articulation
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
scapular elevation
occurs when the scapula moves in a superior direction
32
scapular depressio
occurs when the scapula moves inferiorly
33
scapular protraction
occurs when the scapula moves away from the posterior midline
34
scapula retraction
occurs when the scapula moves back toward the inferior posterior midline
35
scapular upward rotation
inferior angle of scapula rotates up and away from the vertebral column
36
scapular downward rotation
the return to the resting position from the upwardly rotated position
37
scapular tilt
occurs when the shoulder joint goes into hyperextension. The superior end of the scapular tilts anteriorly while the inferior end tilts posteriorly
38
scapular winging
the posterior lateral movement of the vertebral border of the scapula in the transverse plane
39
shoulder joint flexion
shoulder girdle upward rotation, protraction
40
shoulder joint extension
shoulder girdle downward rotation, retraction
41
Shoulder joint hyperextension
shoulder girdle scapular tilt
42
shoulder joint abduction
shoulder girdle upward rotation
43
shoulder joint adduction
r girdle downward rotation
44
shoulder joint medial rotation
shoulder girdle joint protraction
45
shoulder joint lateral rotation
shoulder girdle joint retraction
46
shoulder joint horizontal abduction
shoulder joint girdle retraction
47
shoulder joint horizontal adduction
shoulder joint girdle protraction
48
scapulohumeral rythm
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
muscles of the shoulder girdle
Trapezius, levator scapula, rhomboids, serratus anterior, pectoralis minor
50
acromioclavicular serapation
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
Clavicular fractures
most frequent broken bone in children.
52
shoulder girdle
has both linear and angular motions
53
inferior angle
point of reference for scapular rotation
54
scapulohueral rythm
shoulder girdle and shoulder combined motions
