Test for July 12

Accessing the medial portion of the serratus anterior by curling your fingers around the medial border scapula, your fingers will inherently have to work through the bellies of which 2 muscles?

Elevate the scapula

An action to ask your partner to perform to feel the levator scapula contract is?

Deltoid

As you follow the biceps brachii belly proximally, it becomes deep to which muscle?

Extension

Bilateral contraction of the upper fibers of the trapezius will create what movement of the head & neck?

Bring pectoralis major off the chest wall & allows breast tissue to fall away

Flexing the shoulder & pulling it anteriorly while you palpate the pectoralis major in a side lying position has which 2 benefits?

Laterally rotate & abduct the shoulder 45*

How can you position the shoulder to bring the belly of the coracobrachialis to a superficial position?

Deltoid

If you follow the fibers of the infraspinatus laterally, they converge underneath which muscle?

Deltoid

If you follow the fibers of the pectoralis major laterally, they blend with the fibers of which muscle?

Pectoralis major & anterior deltoid

In anatomical position, the coracobrachialis is deep to which 2 muscles?

Inferior & lateral

In which 2 directions do you want to move from the coracoid process to locate the subscapularis tendon?

Teres minor

Is smaller that teres major & laterally rotates the shoulder

Teres major

Medially rotates the shoulder

Latissimus dorsi & pectoralis major

Most of the serratus anterior is deep to the scapula & which 2 muscles?

Adduct & elevate the scapula are 2 synergistic actions; the trapezius upwardly rotates the scapula, while the rhomboids downwardly rotate it.

Name 2 actions in which the trapezius & rhomboids are synergists & one action in which they are antagonists?

Unscrewing a water bottle

Name an everyday action in which the biceps brachii's ability to supinate the forearm would come in handy

Hugging

Name an everyday action in which you use your pectoralis major

Lateral border

One palpatory distinction between the teres major & latissimus dorsi is that the teres attaches to the ? of the scapula.

Antagonist

The actions of the deltoid's anterior & posterior fibers make it an ? to itself?

Thick superficial fascia

The dense quality of the infraspinatus is due to the its?

Glenohumeral

The four rotator cuff muscles encompass & stabilize the ? joint.

splenius capitis & posterior scalene

The levator scapula is situated between which 2 muscles in the lateral side of the neck?

Teres major & teres minor

The long head of the triceps brachii weaves between which 2 muscles before attaching to the infraglenoid tubercle?

Communicating your intentions

The most important aspect when palpating near the breast tissue is?

Supraspinatus

The only rotator cuff muscle not involved with rotation of the shoulder is the?

Trapezius

The origin of the deltoid is identical to the insertion of which muscle?

Clavicular, sternal & costal

The pectoralis major is divided into these 3 sections.

Brachial plexus, axillary artery & axillary vein

The pectoralis minor has the potential to create neurovascular compression on which 3 vessels?

Trapezius & erector spinae

The rhomboids are deep to the ? Muscle & superficial to the ? muscles?

Rhomboids

The serratus anterior abducts the scapula, making it a direct antagonist to the?

Subscapular fossa & serratus anterior

The subscapularis is sandwiched between which fossa & which muscle?

Biceps brachii

The subscapularis tendon can be located between the 2 tendons of which muscle?

Bicipita aponeurosis

The thin sheet of fascia extending from the distal biceps brachii tendon is called the?

Depress

The upper fibers of the trapezius elevate the scapula, so the lower fibers must ? the scapula?

Deltoid

To access the supraspinatus tendon, you need to sink your thumb tip through which muscle?

Adduction of the scapula

To feel the middle fibers if the trapezius contract, you could ask your partner to perform which action?

Pectoralis major

To locate the belly of the coracobrachialis, from which muscle would you slide off & into the axilla?

Flex the shoulder to 90*; then horizontally adduct & laterally rotate the shoulder 10*

To locate the infraspinatus & teres minor tendons in a supine position, how would you position your partner's shoulder?

Trapezius

To locate the supraspinatus belly, you must palpate through which muscle?

Olecranon process

To outline the distal tendon of the triceps brachii, which bony landmark do you want to locate?

Spine of the scapula, medial border & lateral border

What 3 bony landmarks can you lay your fingers along to isolate the belly of the infraspinatus?

Abduct the shoulder

What action can you ask your partner to perform in order to contract all fibers of the deltoid?

Medially rotate the shoulder

What action could you ask your partner to do to gently contract the subscapularis?

Extend the elbow against added resistance

What action could you ask your partner to perform to feel the contraction of the long head of the triceps brachii?

Abduction of the shoulder

What is the best action to ask your partner to perform to feel the supraspinatus contract?

Shifts the cervical TVP's further anterior, gives the levator more palpable tension & shortens & softens the overlying trapezius

When accessing the levator scapula in a supine position, the benefits of rotating the head 45* away from the side you are palpating include?

Latissimus dorsi & teres major

When accessing the subscapularis from a side lying position, under what 2 muscles should you slide your thumb?

Grasp tissue & let it slip through fingers; feel for the muscles fibrous texture

When palpating the latissimus dorsi, how can you discern the muscle tissue from the superficial skin?
