|
What is scapulohumeral rhythm? |
2° of shoulder abduction must be accompanied by 1° of scapular upward rotation |
|
What are the joints of the shoulder girdle |
Sterno clavicular, acromioclavicular scapulothoracic, glenohumeral |
|
Ligaments of the shoulder girdle |
Sterno clavicular, costo clavicular interclavicular |
|
What is the main purpose of the costo clavicular ligament? |
Limits clavicular, elevation |
|
What does the sterno clavicular ligament do? |
The anterior portion limit supposed to your emotion, the posterior portion limits the anterior Motion |
|
What is the main function of the inter-clavicular ligament? |
Limits clavicular, depression |
|
Describe this ac joint |
It is a gliding plane joint synovial it links scapular motion to the lateral end of the clavicle. It’s very stable. |
|
Describe this sternoclavicular joint |
Saddle joint synovial joint with three planes of motion, articulating disc supported by ligaments only bony attachment |
|
Describe the scapulothoracic joint |
It’s not a true joint. It’s movements include elevation and depression, protraction and retraction, upward and downward rotation, and tilting. |
|
In terms of the sternoclavicular joint, which part moves in which stays put |
The clavicle moves the sternum stays |
|
What are the ligaments of the AC joint? |
Acromioclavicular Coração clavicular coracoacromial |
|
What is the purpose of the acromioclavicular ligaments? |
Hold acromion process to clavicle, preventing dislocation |
|
What is the purpose of the Coração clavicular ligament? |
Stability allows scapula to suspend from the clavicle prevents backward motion in rotation of scapula |
|
Which AC joint forms of protective arch in supplies support to head of humorous went upward. Force is applied. |
Coracoacromial ligament |
|
What are the scapulothoracic joint elevators? |
Upper trap levator scapula rhomboids |
|
What are the scapulothoracic joint depressors? |
Lower trap, peck, minor middle trap, serratus anterior |
|
Starting from inferior angle in moving clockwise name the muscles that attach to the posterior of the right scapula |
Rhomboid, lower, mid trap, levator upper trap |
|
Attaches as a rim to the articular cartilage of the glenoid fossa |
Glenoid labrum |
|
What are the rotator cuff muscles sits? |
Supraspinatus, infraspinatus, teres, minor in subscapularis |
|
This ligament attaches between the coracoid process in the greater tuberosity |
Coracohumeral |
|
This deep is the socket helps seal the joint provide stability almost doubles the depth |
Glenoid labrum 30 |
|
This attaches to the Superior glenoid tubercle and acts as an extension of the glenoid labrum |
Long-head of the bicep |
|
What are the GH joint abductors? |
Supraspinatus anterior deltoid middle delt |
|
What are the GH joint flexors? |
Interior delt pec, major clavicular portion, coracobrachialis, biceps |
|
Why is upward rotation needed for the motion of the GH joint? |
Due to scapulohumeral rhythm, it is needed to maintain length tension, relationship to produce contractile power of flexors and abductors |
|
What are the GH extensors? |
Let’s teres major pack, major post dealt, long head of the tricep |
|
Which muscles produce the lowest torque out of all GH muscle groups |
External rotators |
|
What are the external rotators of the GH |
Infraspinatus, teres, minor posterior dealt subscapularis |
|
what does the girdle do when the shoulder flexes |
upward rotation protraction |
|
what does the girdle do when the shoulder extends |
downward rotation retraction |
|
what does the girdle do when the shoulder hyperextends |
scapular tilt |
|
what does the girdle do when the shoulder abducts |
upward rotation |
|
what does the girdle do when the shoulder adducts? |
downward rotation |
|
what does the girdle do when the shoulder medially rotates |
protracts |
|
what does the girdle do when the shoulder laterally rotates and horizontally abducts? |
retracts |
|
what does the girdle do when the shoulder horizontally adducts? |
protracts |
|
which joint is separate from the shoulder girdle? |
glenohumeral |
|
is the gh stable |
