Chapter 5 Flashcards
serve as attachments for most muscles of the shoulder joint
Scapula, clavicle, and humerus
No the specific landmarks and be able to locate them
be able to locate them
Name one of the joint of shoulder joint
glehumerual joint
Glemhumerol is what type of joint and describe its movement?
multiaxial; ball and socket; most movable : movable in all planes
Relative lack of static stability from ligaments increases importance of …..
dynamic stability
Movement of humerus anteriorly
flexion
Movement of humerus posteriorly
extension
Movement of humerus along its long axis away from midline
External rotation
Movement of humerus along its long axis towards midline
Internal rotation
Upward lateral movement of humerus
abduction
Downward medial movement of humerus
adduction
Movement of humerus in horizontal plane toward (across) the chest
Horizonal adduction
Movement of humerus in horizontal plane away from the chest
Horizontal abduciton
Movement of humerus in a diagonal plane toward the midline of the body
diagonal adduction
Movement of humerus in a diagonal plane away from the midline of the body
diagonal abduction
True or falseMost movements of the humerus involve scapula movement
true
Total range of motion in the shoulder arises from the pairing of the …….joint and the ….girdle
glenohymeral joint and the shouder girdle
For every….. of glenohumeral motion, there is …. of scapula motion
For every 2 ° of glenohumeral motion, there is 1 ° of scapula motion
Range of motion:
Without shoulder girdle movement:
:
95° abduction
95 ° flexion
With shoulder girdle movement
total abduction
Results from: …. scapula upward rotation, ……scapula elevation, …..of glenohumeral abduction
….. flexion
With shoulder girdle movement
175°
Results from: 60 ° scapula upward rotation, 25 ° scapula elevation, 95 ° of glenohumeral abduction
175 °
name all the msucles of the shoulder joint
Anterior
Pectoralis major
Coracobrachialis
Subscapularis
Superior
Deltoid
Supraspinatus
Posterior Latissimus dorsi Teres major Infraspinatus Teres minor
Coracobrachials can be strengthed by what
lat pulls and bench press
Pectroalis major can be strengthed by what
pull ups, bench press, throwing , push ups
: Any movement of humerus on the scapula will involved part or all of the deltoid
True or false
true
…. stabilizes scapula as deltoid pulls on humerus
Trapezius
Deltoid can be strengthened by
Strengthen with sidearm dumbbell raise, abducting and adducting horizontally can emphasize posterior and anterior fibers
Which muscle is considered the broadest muscle?
Latssiumus Dorsi
Latisimus Dorsi muscle can be strengthed by
rowing, chin ups, lat pulls, Rope climbing
Which muscle is the second most commonly injured muscle
Infraspinituius
Provides dynamic stability during throwing
Most injured rotator cuff muscle
Supraspinituis
What are exercises to strengthen pec major?
Throwing,push ups, pull ups , becnh press
exercises to strenghten coracobrachials
