Front 20

Landmarks of Clavicle

Back 20

BUMPS ON BOTTOM

Front 21

What end of the sternum provides attachment for the clavicle?

Back 21

STERNAL END

Front 22

Name the 3 parts of the sternum.

Back 22

MANUBRIUM, BODY, XIPHOID PROCESS

Front 23

The joint with direct attachment to the trunk; Synovial joint; motion occurs in 3 planes

Back 23

STERNOCLAVICULAR JOINT

Front 24

Connects the acromion process with lateral clavicle; gliding motion occurs in all planes

Back 24

ACROMIOCLAVICULAR JOINT

Front 25

What does a labrum do?

Back 25

ITS IS A FIBROCARTILAGE RING THAT DEEPENS A FOSSA TO PROVIDE MORE STABILITY

Front 26

Movement of the scapula is accompanied by glenohumeral joint movement & vice-versa. Impairment of one joint will impair function of the other. EX: shoulder flexion accompanies upward scapular rotation.

Back 26

Front 36

What is the scapulohumeral rhythem ratio?

Back 36

2:1 ratio

Front 37

The first 30 degrees of shoulder joint motion is purely glenohumeral.

Back 37

After that, for every 2 degrees of shoulder flexion or abd., the scapula rotates 1 degree
