Test 2 Flashcards
Where does the anterior deltoid insert?
Deltoid tuberosity (humerus)
Where does the middle deltoid insert?
Deltoid tuberosity (humerus)
Where don’t the posterior deltoid insert?
Deltoid tuberosity (humerus)
extends longitudinally from the occipital bone to the lower thoracic vertebrae and laterally to the spine of the scapula
Trapezius muscle
What 3 groups is the trapezius muscle broken up into?
- upper fibers
- middle fibers
- lower fibers
This part of the trapezius muscle supports the arm
Upper fibers
This part of the trapezius muscle retracts the scapulae
Middle fibers
What are the insertion points of the trapezius muscle?
- lateral 1/3 clavicle
- acromion
- scapular spine
Insertion of latissimus Dorsi?
Bicipital groove (humerus)

Lesser tubercle (humerus)
-Supraspinatus
-infraspinatus
-teres minor
Make up the:

Greater tubercle
Insertion of teres minor?
Greater tubercle
Insertion of subscapularis?
Lesser tubercle
Insertion of rhomboid major?
Medial border, below scapular spine
Insertion of rhomboid minor?
Medial border at scapular spine
Insertion of levator scapulae?
Medial border above scapular spine
Insertion of serratus anterior?
Medial border of scapula
Insertion of pectoralis major?
Bicipital groove
Insertion of pectoralis minor?
Coracoid process
Insertion of subclavius?
Middle 1/3 of clavicle
Insertion of biceps brachii?
Radial tuberosity
Insertion of triceps?
Okecranon process
Insertion of coracobrachialis?
Middle 1/3 of the humerus
What does the shoulder girdle consist of?
- sternum
- clavicle
- scapula
On which side of the clavicle is the sternal extremity?
The end where the clavicle touches sternum
Where is the acromial extremity on the clavicle?
The opposite end of the sternum
Which joint is considered to be the most mobile and least stable joint in the body?
Glenohumeral
synovial ball-and-socket style diarthroidal joint
Glenohumeral joint
joint is formed from the combination of the humeral head and the glenoid fossa of the scapula
Glenohumeral joint
junction between the acromion and clavicle
Acromioclavicular joint
Synovial, Gliding/Plane Joint
Acromioclavicular joint
Joint allows the ability to raise the arm above the head
Acromioclavicular joint
Joint at Sternal end of clavicle and sternum
Sternoclavicular joint
plane style synovial joint, and has a fibrocartilage joint disk
Sternoclavicular joint
Ligaments are very strong, often resulting a fracture of the clavicle before a dislocation of the SC joint
Sternoclavicular joint
Coracoid process to greater tubercle of the humerus
Coracohumeral ligament
Humerus to glenoid –Main source of stability •Superior •Middle •inferior
Glenohumeral ligament
