Question 2:
Scapular Elevation
Answer:
shoulder shrug
Question 3:
Scapular Depression
Answer:
opposite of elevation
Question 4:
Scapular Retraction
Answer:
pinch shoulder blades together
Question 5:
Scapular Protraction
Answer:
opposite of retraction
Question 6:
Scapula
Answer:
aka shoulder blade; spine, superior angle, inferior angle, medial/vertebral border,
lateral/axillary border, acromion process, & coracoid process
,Question 7:
Clavicle
Answer:
aka collar bone; distal/lateral end & proximal/medial end; "S" shapedaka collar bone;
distal/lateral end & proximal/medial end; "S" shaped
aka collar bone; distal/lateral end & proximal/medial end; "S" shaped
aka collar bone; distal/lateral end & proximal/medial end; "S" shaped
Question 8:
Sternum
Answer:
The best answer is determined by the key concept tested in the question.
Question 9:
Humerus
Answer:
head, greater tuberosity, lesser tuberosity, bicipital groove, shaft; GH jt. is ball & socket jt. but
glenoid fossa if flat & humeral head is round, causing increased movability but decreases
stability
Question 10:
Thorax
Answer:
ribs; specifically posterior aspect of ribs 2-8
Question 11:
Joints
Answer:
glenohumeral (GH), acromioclavicular (AC), sternoclavicular (SC), & scapulothoracic (ST)
Question 12:
Anterior Muscles
Answer:
FL shoulder & may FL elbow
,Question 13:
Posterior Muscles
Answer:
EXT shoulder & may EXT the elbow
Question 14:
Lateral Muscles
Answer:
ABD shoulder
Question 15:
Medial Muscles
Answer:
ADD shoulder
Question 16:
Deep Muscles
Answer:
IR & ER shoulder
Question 17:
Deltoids
Answer:
forms "cap" of the shoulder; 1 muscle w/ 3 parts; originate an acromion process & insert on
lateral shaft of humerus
Question 18:
Anterior Deltoid
Answer:
shoulder FL
, Question 19:
Middle Deltoid
Answer:
shoulder ABD
Question 20:
Posterior Deltoid
Answer:
shoulder EXT
Question 21:
Biceps brachii
Answer:
1 muscle w/ 2 heads (long & short); crosses shoulder & elbow causing shoulder & elbow FL
Question 22:
tendon of long head runs through biceptal groove of humerus & over the humeral head to
attach to the scapula, resulting in a tendon running b/w 2 bones; when shoulder in neutral RO
or ER, Biceps tendon is ok during shoulder FL; when shoulder in IR, Biceps gets pinched under
acromion process during shoulder FL above 90⁰; ER is easier that IR when FL
Answer:
Biceps Tendon
Question 23:
Triceps brachii
Answer:
1 muscle w/ 3 heads; crosses shoulder & elbow to EXT both
Question 24:
Rotator Cuff
Answer:
4 muscles; begin on scapula & end on greater or lesser tuberosity of humerus; stabilizes GH jt.
& shoulder IR & ER; small muscles made for endurance NOT brute strength; Supraspinatus,
Infraspinatus, Teres minor, & Subscapularis
