Shoulder flexion has a normal range of motion of

0-170

The normal range of motion for shoulder external rotation is:

0-60

The extensor digitorum creates movement at which fingers?

2nd-5th

A patient is lying on their stomach with their right arm abducted to 90 degrees, and their elbow bent at 90 degrees. They are holding a full water bottle in their right hand. If they are able to externally rotate their arm in this position, while holding the water bottle, we know that they have at least what muscle grade?

3+

Which joint is reinforced by the ulna and radial collateral ligament?

Elbow

T/F: If the deltoid is paralyzed, full abduction of the shoulder is still possible through solely the supraspinatus.

True

A person is standing facing the sink with a cabinet located directly above the sink. The person places a cup from the sink, onto a shelf overhead. Which muscle is the prime mover for this action?

anterior deltoid

A student was resting her arm on an overhead shelf directly in front of her with her elbow fully extended. When she carefully and slowly lowers her arm all the way back to her side what muscles are the prime movers?

anterior deltoid

Which is the insertion of the extensor carpi radials brevis?

base of the 3rd carpal

the radoiocarpal joint is a ___joint with ___degrees of freedom

biaxial; 2 DOF

what is the anatomical name of the finger bones

carpals

During scapulothoracic *upward rotation* occurs at the *acromioclavicular joint* and _____ occurs at the *sternoclavicular* joint.

downward rotation

When the sternoclavicular joint elevates during scapulothoracic elevation (shrugging your shoulders), what action occurs at the acromioclavicular joint?

downward rotation, anterior tilt

A student was resting her arm on an overhead shelf directly in front of her with her elbow fully extended. When she carefully and slowly lowers her arm all the way back to her side. What type of contraction is occurring in this scenario?

eccentric

which position would shorten the length of the triceps

elbow extension

Which of the following reaching tasks would be most difficult for a client with limited internal rotation?

fastening your bra behind your back

Which band of connective tissue forms the "roof" of the carpal tunnel?

flexor retinaculum

which structures pass through the carpal tunnel?

flexor tendons and median nerve

What is true about the scapulohumeral rhythm

for 180 degrees of shoulder abduction, 120 degrees occurs at the GH joint, and 60 occurs at the ST joint

The glenoid labrum supports the glenohumeral joint by:

increasing the size and depth of the articular surface

which bony landmark serves as an attachment site for the tendons of the wrist and hand flexors?

medial epicondyle

Anatomically speaking, what is the proper name of a knuckle joint?

metacarpophalangeal

Where does the axis lie when completing range of motion testing for internal rotation of the shoulder? Where do you place the axis of your goniometer?

olecranon process

Which is a bony landmark NOT found on both the radius and ulna?

olecranon process

What is tendonitis caused by?

overuse

Cori askes a s student a question in class. The student does not know the answer and shrugs their shoulders in response. Which muscles are antagonist to the action of this scenario:

pectoralis minor, lower trapezius

Having "rounded shoulders" can cause the scapula to tilt forward and partially protract and rotate downwards. Prolonged rounded shoulder position may cause tightness to which of the muscles/s:

pectorals major and pectorals minor

Your patient is lying supine on a mat and is able to complete partial range of motion (0-80 degrees) for shoulder abduction in this position. Based on this information alone, how would you grade this patient's muscle strength?

poor minus (2-)

A person is standing facing the sink with a cabinet located directly above the sink. The person places a cup from the sink, onto a shelf overhead. Which of the following is the antagonist to the prime mover?

posterior deltoid

Having "rounded shoulders" can cause the scapula to tilt forward and partially protract and rotate downwards. Prolonged rounded shoulder position may cause the following muscles to be overstretched:

rhomboids and middle trapezius

When the sternoclavicular joint retracts, the arthrokinematics can be described as follows:

rolling and sliding in the same direction

In what plane does flexion/extension of the wrist occur

sagittal

When a concave bone is moving on a convex bone, rolling and sliding occurs in ____ directions

same

Which carpal forms the floor of the "anatomical snuffbox"?

scaphoid and trapezium (near the thumb)

What position of the upper extremity maximally elongates the biceps?

shoulder extension, elbow extension and forearm pronation

Which joint is the attachment point between the axial and appendicular skeletons?

sternoclavicular

What could be a result of paralysis of the muscle because of the loss of the normal 5 degrees of upward rotation of the scapula at rest?

subluxation

The AC joint act as a ______movement against the acromion and the clavicular joint.

subtle gliding

During abduction of the glenohumeral joint, the arthrokinematics are as follows:

superior roll, inferior slide

The static locking mechanism suggest that in order for the glenohumeral joint to statically lock based on the opposing forces produced by gravity and superior capsular ligaments at rest, the following condition must be met:

the glenoid fossa must be upwardly rotated by 5 degrees

Which of the following is true about the muscles that proximally stabilize the shoulder?

they originate on the spine, ribs and cranium

Which bones articulates with the first metacarpal and is the source of the thumbs unique movements?

trapezium

tricep brachii

Which muscle is innervated by the radial nerve?

tricep brachii

which of the following muscles is not a forearm flexor at the elbow?

tricep brachii

which carpal can be best palpated by asking your partner to abduct and adduct her wrist as you palpate just distal to the styloid process of the ulna?

triquetrum

which structure, that course between the medial epicondyle and olecranon process, creates the "funny bone" sensation?

ulnar nerve

Cori ask a student a question in class. The student does not know the answer and shrugs their shoulders in response. What are the prime movers for this action?

upper trapezius, levator scapulae, rhomboids
