Exam 2 Flashcards
chapter 7 part 2
what does the pectoral girdle consist of
clavicle, scapula, and very light girdle
what does the pectoral girdle attach
upper limbs to axial skeleton and attachment for muscle movemenr for upper limbs
3 joints in pectoral girdle
sternoclavicular joint
acromiclavicular joint
scapulothoracic articulation
Medial end of Clavicle to Sternum (Clavicular Notch)
sternoclavicular joint
Distal end to Acromion Process of Scapula
acromioclavicular joint
(Not truly a joint) = Muscle to Vertebrae
scapulothoracic articulation
degree range of motion in shoulder
180
scapula not attached to axial skeleton means
freely moves across thorax, arm moves with it
what contribute to ROM
sternoclavicular and AC joints
glenohumeral joint is
shallow, poor reinforcement
what is not attach to axial skeleton and freely moves across thorax, and arm moves with it
scapula
when bone is a slender s shaped bone
clavicle
what bone act as braces and holds scapula and arms lateral and is away from narrower upper thorax
clavicle
sternal end is what direction
medial
acromial end is what direction
lateral
what bone is not strong and susceptible to fracture
clavicle
shoulder blade bone
scapula
what bone lies on dorsal rib cage and between ribs 2-7
scapula
what bone has acromion process and ac joint
scapula
what bone has a coracoid process- attachment for shoulder and arm muscles, and anchors biceps
coracoid process
the scapular spine is anterior or posterior
posterior
what bone articulates with scapula, radius and ulna
humerus
what articulates with glenoid cavity
humerus
what is a common fracture site
surgical neck
humeral head removal due to
disease or injury
rotator cuff muscle attachment
greater tubercle and lesser tubercle
biceps brachii tendon
intertubercular grooce
deltoid muscle attach
deltoid tuberosity
radial nerve
radial groove
depression for olecranon process of ulna during elbow extension
olecranon fossa
humerus articulates with radius
capitulum
humerus articulates with ulna
trochlea
forearm muscle attachment (ulnar nerve behind medial= funny bone)
medial and lateral epicondyle
golfer’s elbow, pitcher’s elbow, avulsion fraction
medial epicondylitis
due to overuse, repetitive motion. pain and swelling in elbow, decreased ROM, unable to throw
medial epicondylitis
how do you treat epicondylitis
rest, ice, NSAIDs (medial), and RICE (lateral)
medial elbow bone
ulna
brachialis muscle attachment
ulnar tuberosity
lateral wrist
radius
