AROM GONI
100
This muscle originates on the subscapular fossa of the scapula and inserts on the lesser tubercle of the humerus.
What is the subscapularis muscle?
100
What are the upward rotators of the shoulder?
Upper trapezius, lower trapezius, and serratus anterior.
100
This muscle is innervated by cranial nerve XI.
Upper trapezius.
100
The separation of the clavicle from the scapula
Caused by a hard hit or fall on the shoulder or outstretched arm.
What is AC joint seperation?
100
What is "normal" ROM for shoulder flexion in degrees?
180
200
Name the muscle that originates on the occipital bone, nuchal ligament and upper cervical spinous process.
Hint: Insertion on the outer third of clavicle, acromion process.
What is the upper trapezius?
200
Name all the muscles that do shoulder (plain) ABduction.
Middle deltoid and supraspinatus.
200
When this nerve is damaged, the serratus anterior is weak. Scapular winging also occurs.
What is the long thoracic nerve?
200
When the anterior/inferior portion of the labrum is torn away from the glenoid fossa.
What is a bankart lesion?
200
What is normal shoulder extension ROM measured in degrees according to the AMA?
50 degrees
300
Name the muscle:
O: spinous processes of the middle and lower thoracic vertebrae
I: Base of scapular spine
What is the lower trapezius?
300
List the muscles that are the prime internal rotators of the shoulder.
Anterior deltoid
Subscapularis.
Teres major
Latissimus dorsi
Pectoralis major
300
The deltoids and teres minor share this nerve that is a part of the brachial plexus.
Axillary
300
An overuse condition that involves compression between the acromial arch, humeral head, and soft tissue structures such as the coracoacromial ligament, rotator cuff muscles, long head of the biceps, and subacromial bursa.
What is impingement syndrome?
300
What is the end feel of shoulder abduction?
Firm.
400
This muscle has an origin via the dorsolumbar fascia and is part of the shoulder joint.
What is the latissimus dorsi?
400
This muscle performs shoulder abduction, flexion, internal rotation, and horizontal adduction.
Anterior deltoid
400
Name two muscles that are innervated by C5 segment of the spinal cord
Could be any of these muscles:
Biceps, infraspinatus, teres minor, subscapularis, deltoids, teres major, pectoralis major, supraspinatus
400
Is a group of disorders that occur when the nerves of the brachial plexus and or subclavian artery and vein become compressed in the thoracic outlet
What is thoracic outlet syndrome?
400
What are the landmarks for measuring external rotation of the shoulder?
Fulcrum: olecranon process
Proximal Arm: Perpendicular or parallel with the floor
Distal arm: Ulna
500
This muscle has two portions. Name the portion that has the action of shoulder flexion for the first 60 degrees.
What is the pectoralis major clavicular portion?
500
Name the muscle and what actions it performs.Latissimus Dorsi
Shoulder extension, adduction, medial rotation, hyperextension
500
Damage to this nerve would result in loss of shoulder abduction and weakened shoulder lateral rotation.
The axillary nerve.
500
Which parts of a joint are replaced or resurfaced in a TOTAL shoulder arthroplasty?
Head of humerus, glenoid fossa,
500
What are the landmarks for measuring shoulder abduction with a goniometer?
Fulcrum: Acromial process
Proximal arm: Parallel with sternum
Distal arm: Anterior mid line of humerus
