Functional Anatomy Exam 3 RATS

The shoulder complex consists of

Clavicle

Scapula

Humerus

The glenohumeral joint is the articulation between

The humerus and the scapula.

The movements of that occur at the scapulothoracic joint include all of the following

Gliding: elevation, depression, abduction, adduction

Rotation: internal, external, upward, downward

Tilt: anterior, posterior

What is NOT a reason scaption is important?

It allows for a 1:1 movement between the scapula and humerus throughout all mobility

The only true joint that attaches the UE to the axial skeleton is

sterno-clavicular joint

What are the movements of the glenohumeral joint?

Flexion, extension

Internal rotation and external rotation

Abduction, adduction

What is part of the subacromial space?

Subacromial bursae

Long head of the biceps

Tendons of the infraspinatus and supraspinatus

What are the actions of the lower trapezius?

Depress the scapula

Upwardly rotate the scapula

What muscle anchors the scapula to the rib cage?

Serratus anterior

The scapula moves throughout multiple planes during functional use of the upper extremity. Which movement is INCORRECTLY described?

downward rotation—depression with abduction

What is NOT part of the rotator cuff?

Teres major

What is NOT true for scapulohumeral rhythm?

The scapula generally moves in a 1:1 ratio irrespective of the elevation of humeral elevation

Which rotator cuff muscle is most often injured in overhead activities due to the significant role it plays in overhead stability of the upper extremity?

Supraspinatus

What are consequences of a consistently slouched posture?

Tightening of the pec minor and major

Stretching of the scapular stabilizers

Potential weakness of the scapular stabilizers

The Empty Can Test is a special test that can be used to isolate which muscle when assessing rotator cuff pathology?

Supraspinatus

Anatomical compression of the brachial plexus as it passes beneath the clavicle and pectoralis minor insertion is known as:

Pectoral neuropathy

Thoracic outlet syndrome

The radial nerve...

comes from the posterior division of the Brachial Plexus and innervates all of the muscles in the posterior compartment of the forearm.

A complete injury to the axillary nerve would result in

Paralysis of the teres minor and deltoid muscles.

Loss of sensation over a small part of the lateral upper arm.

Weakness or loss of abduction and external rotation of the shoulder

The ulnar nerve is often irritated when striking the "funny bone", producing a tingling sensation down the inside of the forearm and little finger

True

All of the following are innervated by the musculocutaneous nerve except:

Pectoralis minor

In carpal tunnel syndrome, the median nerve is compressed by increased pressure or swelling. It produces loss of sensation and muscle weakness which leads to clumsiness and dropping items.

True

Functionally speaking, the axillary nerve is important to all activities....

where the hand is needed at head height or above

Functionally speaking, the ulnar nerve is involved in all activities requiring....

Fine manipulative movements of the fingers and in the stability of the hand during power grips.

The suprascapular nerve is a branch of the trunk formed by the lower roots C7 and C8.

False

In the case of a spinal cord injury, it is important to relate the spinal segmental level to the muscles and the areas of the skin supplied.

True
