Kinesiology Exam 2 Flashcards
what plane does elevation/depression take place
frontal
what plane does protraction/retraction take place
transverse
what plane does upward roation/downward rotation take place
frontal plane
is the manubrium and sternum part of shoulder girdle
no it is not
what are bones part of the shoulder girdle
scapula and clavicle
sternal end of clavicle shape
rounded
acromial end of clavicle
where the scapula meets
what is the purpose of the clavical
moves in response of the scapula moving
what are the bones of the scapula
corocoid process, acromion process, spine, medial and lateral borders, inferior angle, superior angle, glenoid fossa
what is the corocoid process
3 layers of muscle covering the scapula,
what is the acromion process
anterior projection of the spine and scapula
what is the numbering of scapula landmarks 1-4
inferior angle, medial border, lateral border, spine (bottom to top)
what type of joint is scapulothoracic
pseudo gliding b/c named by how the muscles fit on the rib cage and not how they move since they don’t have diarthrotic joints
what type of joint is sternoclavicular
glidding
what type of joint is acromioclavicular
glidding
where do the 5 muscles of the shoulder girdle insert
at the scapula
what direction should a stretch be done
in the opposite direction as the action
7 muscles of shoulder girdle
pectoralis minor, serratus anterior, upper trapezius, middle trapezius, lower trapezius, rhomboid, levator scapula
is the rhomboid deep or superficial and what muscle is it near
deep, near the middle trap
what muscles of the shoulder girdle do protraction
pectoralis minor and serratus anterior
what movements does pectoralis minor do
protraction and depression
what movements does serratus anterior do
protraction and upward roation
what movements do upper trapezius do
elevation
is upper trap superficial or deep
superfiicial
where does upper trapezius originate
at the skull
what movements does lower trap do
depression
what muscles do depression
pectoralis minor and lower trap
what movements does rhomboid do
retraction
what movements do levator scapula do
elevation and downward rotation
what are the anterior should girdle muscles
pectoralis minor and serratus anterior
what are the posterior should girdle muscles
3 trapezius, rhomboid, levator scapula
what skeleton do the muscles that move the scapula insert
axial b/c insert at scapula
purpose of manual muscle tests
assess ROM, test strength compared to uninjured side, compare w/ pre-injured data
what does the break test include
- contract muscle against gravity
- isometric contraction
see if there is pain with either movement
no pain= pass
equal strength= do resisted ROM test next
grading scale for MMT
1- can’t move at all or see any contraction
2-can’t do contraction against gravity, can see/palpate some contraction
3-can do contraction on own against gravity but can’t hold w/ resistance
4-go through moderate resistance ROM
5- full strength w/ resisted
glenohumeral joint defined by
movements of humerous, origin (scapula or clavicle), insertion at humerous
what type of joint is glenohumeral
ball and socket= diarthrotic
what may indicate a problem w/ glenohumeral joint
problem w/ full ROM of scapula
bones of glenohumeral joint at scapula
glenoid fossa, supraspinatus fossa, intraspinatus fossa, subscapular fossa
what bone is at the head of the humerus
glenoid fossa
what fossa is posterior on scapula
supraspinatus
what fossa bone is anterior on scapula
subscapular fossa
is the deltoid tuberosity lateral or medial
lateral
what side is the greater tuberosity side found
lateral side
what side is the lesser tuberosity found
medial
what divides greater and lesser tuberosity
intertubercle/bicepital groove
pectoralis major motions
horizontal flexion and adduction
what muscles of the glenohumeral joint do adduction as their prime action
pectoralis major and latissimus dorsi
what are the helpers of glenohumeral joint
deltoid, teres major, coracobrachialis, rotator cuff
what are the 4 muscles of the rotator cuff
supraspinatus, infraspinatus, teres minor, subscapularis
