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

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
