500

What are the five branches of the brachial plexus and what muscles do they innervate?

Musculocutaneous - Biceps brachii, Brachialis, Coracobrachialis

Axillary - Deltoid and Teres minor

Radial - Triceps brachii, Anconeus, Supinator, Brachioradialis, extensors of the forearm

Median - Forearm Flexors, Forearm Pronators, Flexor pollicis longus/brevis, abductor pollicis brevis, oponens pollicis

Ulnar - Flexor carpi ulnaris, Flexor digitorum profundus, multiple hand muscles

Muscle Distribution

100

What muscle is innervated by the thoracodorsal nerve?

Latissimus Dorsi

200

Name the muscles that comprise the rotator cuff and the nerves that innervate them.

Rhonan - Let Tony 5-star you

Supraspinatus and Infraspinatus - suprascapular nerve

Teres Minor - Axillary nerve

Subscapularis - Upper/Lower Subscapular nerve.

If you do it +1000, if you don't -200

300

What are the muscles innervated for the anterior interosseus nerve in the forearm?

Flexor Pollicis Longus

Flexor Digitorum Profundus

Pronator Quadratus

400

Which muscles are primarily responsible for ab/adduction of all the fingers and what are they innervated by?

Palmer and Dorsal interossei, Ulnar Nerve

500

What muscle forms the Arcade of Frohse?

Two heads of the Supinator

Cutaneous Distribution

100

What nerve supplies the lateral shoulder around the region known as the regiments patch?

Upper Lateral Cutaneous Nerve

200

What are two regions of the hand the recurrent median nerve supplies cutaneous distribution to?

Palmer branch - Anterior thumb and palm of first three digits to base of MCP joint.

Palmer Digital branch - Anterior digits of 2-3, DIP of posterior 2-3, DIP and medial edge of thumb.

300

What are the three cutaneous distributions of the radial nerve?

Posterior Cutaneous Nerve of the arm

Posterior Cutaneous Nerve of the Forearm

Superficial Radial Nerve

400

This nerve begins as a cord in the brachial plexus, but becomes a cutaneous nerve in the forearm. What are these two nerves?

Tory: Facetime Reid and ask him if the rash in his crotch is clearing up

Musculocutaneous nerve and Lateral Antebrachium Cutaneous nerve.

If he's in the car with others - 500

If he's alone or doesn't answer - 200

500

Describe the cutaneous pattern of the upper extremity.

Upper Lateral Cutaneous Nerve

Lower Lateral Cutaneous Nerve

Posterior Cutaneous Nerve of the Arm

Medial Cutaneous Nerve of the Arm

Lateral Antebrachial Cutaneous Nerve

Medial Cutaneous Nerve of the Forearm

Posterior Cutaneous Nerve of the Forearm

Median Nerve - Palmer and Digital branches

Ulnar Nerve - Palmer, Digital, and Dorsal branches

Superficial Radial Nerve

Clinical 1

100

What does TOS stand for? How would you define it?

Tony - Chug a diet 7-Up and don't burp for 1 minute.

Thoracic Outlet Syndrome, it is compression of the nerves and/or arteries traveling with the brachial plexus with common entrapment sites at the scalenes, subclavius, and pec minor.

+700 if you do it

200

Verbalize and demonstrate Adson's test for Anterior Scalene syndrome and what indicates a positive test.

in relation to examined side - ipsilateral rotation, contralateral flexion, and extension, patient may be encouraged to take a deep breath. if radial pulse is weakened or reproduction of symptoms occur, exam is positive.

300

Verbalize and demonstrate how you would perform the test for the latissimus dorsi.

Patient lies supine, support opposite ASIS, internally rotate arm, resist abduction force applied by physician.

400

Explain what the pinch test (sign of OK) is testing for and how to determine a positive test?

AIN, AIN supplies flexor pollicis longus and flexor digitorum profundus to flex DIP, if patient is unable to perform Sign of OK, there is an interference in the nerve telling these muscles to function.

500

Name all 5 MSR tests we have discussed and what they include?

Not typing this, sorry lol.

Clinical 2

100

Reflexes are good for testing what type of issue?

Spinal root legions/spinal injuries/spinal disease

200

Verbalize and demonstrate Wright's test for hyperabduction syndrome and what indicates a positive test.

Passively raise the patients arm up and back while feeling radial pulse, weakened pulse is indicative of a positive test.

300

Explain Froment's Paper test and what you are testing for.

Adduct thumb to pinch paper, if DIP of thumb flexes to perform test successfully, ulnar nerve is not innervating adductor pollicis correctly and AIN is working to compensate.

400

What are some ways to differentiate between Pronator Teres Syndrome and Carpal Tunnel Syndrome?

The Palmer branch of the recurrent median nerve does not pass through the carpal tunnel. CTS will have pain in only the first two digits of the hand, PTS will have pain in both the Palmer and Palmer digital branches of the recurrent median nerve.

500

With a partner, demonstrate examining the 5 dermatomes of the upper extremity.

C5 - Lateral Brachium

C6 - Anterolateral Antebrachium to tip of thumb

C7 - Anterior Antebrachium to tip of digits 2-4

C8 - Anteromedial Antebrachium to tip of 5th digit

T1 - Medial Brachium to mid Antebrachium
