Unit E Quiz
Which of the following groups are the prime movers in elbow flexion?
(B, B, B) Biceps, brachialis, brachioradialis
Your patient is positioned on her right side with her left elbow flexed to 90 degrees and is holding a 3# weight inher hand with her left elbow resting & stabilized on her left side, she rolls her humerus to bring her left forwarm/wrist up toward the ceiling. What motion did she make, what type of contraction, using which two muscles?
(L) shoulder ER, isotonic concentric, using infraspinatus & teres minor
Your next client has shoulder pain and loss of motion due to inflammation and fibrosis of the shoulder joint. The most likely diagnosis is which of the following?
Adhesive capsulitis
Which muscle originates on the lateral clavicle, the top of the acromion, and the scapular spine and inserts on the midpoint of the humerus on the lateral side?
All deltoid fibers
Which muscle flexes the shoulder through its entire range?
Anterior deltoid
Damage to which of the following nerves could result in weakness of the deltoid muscle?
Axillary nerve
Which muscle originates on the distal half of the humerus (anterior surface) and inserts on the coronoid process and the ulnar tuberosity of the ulna?
Brachialis
Which muscle originates on the humeral lateral condyle and inserts on the radial styloid process?
Brachioradialis
Which muscle originates on the medial one-third of the clavicle and inserts on the lateral lip of the bicipital groove?
Clavicular pec major
When you have a patient do a "chair push up" exercise to strengthen the elbow triceps, what type of kinetic chain activity is this?
Closed chain concentric and eccentric from start to finish
You are asked to palpate for tenderness at the coracoid process of the scapula. If you locate tenderness at this spot, the patient may have soft tissue inflammation at the origin of which of the following muscles?
Coracobrachialis
Which bony landmark of the humerus is located on the lateral side near the midpoint of the shaft?
Deltoid tuberosity
(T/F) The coracohumeral ligament attaches from the lateral coracoid to the medial greater tubercle and serves to stabilize the lateral portion of the shoulder joint capsule.
False
(T/F) Your patient is unable to fascen his seatbelt with his (R) hand. As his PTA, you should recognize that the sternal pectoralis major and the levator scapula would be weak preventing him from this task.
False
The reason you have your client laterally rotate his shoulder when moving between 90 and 180 degrees of shoulder abduction is to prevent what structure from hitting the acromion process?
Greater tubercle
Which of the following muscles perform shoulder hyperextension?
Latissimus dorsi
Which muscle originates on the infraglenoid tubercle of the scapula and inserts on the olecranon process of the ulna?
Long head of triceps
You are palpating a person's shoulder and note that she has pain in the bicipital groove. You determine that this person may be having symptoms of tendonitis of which of the following muscles?
Long head of triceps
The bony landmark located on the distal medial side of the humerus is the
Medial epicondyle
Your patient has point tenderness at the common flexor origin at the elbow. Given this symptom, which diagnosis is likely?
Medial epicondylitis
The latissimus dorsi, subscapularis, and anterior deltoid have which of the following shoulder motions in common?
Medial rotation
Weakness of the pronator teres muscle could indicate trauma to which of the following?
Median nerve
Damage to which of the following nerves could result in weakness of the coracobrachialis muscle?
Musculocutaneous
Which muscle originates on the humeral medial epicondyle and proximal epicondyle and proximal ulna and spans the elbow anteriorly to attach on the lateral surface of the radius near its midpoint?
Pronator teres
The pectoralis major, latissimus dorsi, and teres major have which of the following shoulder motions in common?
Shoulder ADduction
The posterior deltoid, latissimus dorsi, and teres major have which of the following shoulder motions in common?
Some variation of shoulder extension
The rotator cuff muscles serve to hold the humeral head against the glenoid fossa and best serve to facilitate which arthrokinematic motion of the shoulder joint?
Spin
All of the following can contribute to joint subluxation of the glenohumeral joint EXCEPT
Strong lateral capsular ligaments (Are: weight of UE, gravity, shallow glenoid fossa)
The bony landmark located at the posterior lateral side of the radius at the distal end is called the
Styloid process
A patient with specific point tenderness in the axillary region, just ventral to a protracted scapula, may have trigger point inflammation in which muscle?
Subscapularis
Which muscle originates on the anterior surface of the scapula and inserts on the lesser tubercle of the humerus?
Subscapularis
Damage to which of the following nerves could result in weakness of the infraspinatus muscle?
Suprascapular nerve
Which muscles originate on the axillary border of the scapula and insert on the greater tubercle of the humerus?
Teres minor
The carrying angle at the elbow exists because of which of the following phenomena at the distal end of the humerus?
The medial structures extend farther distally than the lateral structures causing cubital valgus
Horizontal abduction of the shoulder occurs in which plane and through which axis using what prime muscle?
Transverse plane through a vertical axis using posterior deltoid.
