Back 11

The Investing Layer of Fascia lies INTERNAL to cephalic & basilic veins in the forearm and likes EXTERNAL to veins in upper portion of the arm.

honestly, so darn random at the moment--think of it investing layer as an iceberg, the top is EXTERNAL.

Front 12

Note when talking about brachial fascia, antebrachial fascia and palmar aponeurosis ...these are all
INVESTING Fascia.

Back 12

These are ALL CONTINUOUS w/each other.

At the cubital fossa, cephalic vein communicates with the basilic vein via the ________________

Back 14

Median cubital vein

Front 15

As the cephalic vein travels up the arm, it pierces the brachial fascia (investing layer) and enters the _______________ triangle.

After this triangle, the cephalic veins pierces the _________________ FASCIA and will become tributary to the __________ VEIN.

Back 15

SMELL YOUR ARMPIT. Go ahead...That's right, your cephalic area just paid TRIBUTE TO YOUR AXILLA. As does the cephalic vein.


As the cephalic vein travels up the arm, it pierces the brachial fascia (investing layer) and enters the DELTOPECTORAL triangle.

After this triangle, the cephalic veins pierces the CLAVIPECTORAL FASCIA and will become tributary to the AXILLARY VEIN.

Front 16

Basilic vein originate on the medial side of the dorsal venous arch, in hand, and on forearm. As the basilic vein travels up arm, it pierces the brachial fascia.

The Basilic vein, along with the brachial vein will contribute to the formation of the vein.

Back 21

The top portion of the supra scapular notch is covered by the SUPERIOR TRANSVERSE ligament. The suprascapular nerve, from the SUPERIOR trunk of Brachial plexus is touching it.

Front 22

Army over navy, etc. BUT

Above the superior transverse ligament run the suprascapular artery and vein-the suprascapular Artery is a branch of WHAT?

Back 22

Above the superior transverse ligament run the suprascapular artery and vein-the SUPRASCAPULAR Artery is a branch of THYROCERVICAL trunk of SUBCLAVIAN ARTERY?

Front 23

Image is showing suprascapular nerve runing below ligament.

Calcification of the superior transverse scapular ligament an impinge on the suprascapular nerve, causing loss of innervation to WHICH 2 muscles?

A patient will have trouble in ABDUCTION or ADDUCTION?

Back 23

Calcification of the superior transverse scapular ligament an impinge on the suprascapular nerve, causing loss of innervation -spinatus muscles (infra+supra).

A patient will have trouble with ABDUCTION of the arm.

NO more boyfriend raising his arm over your shoulder. TOPANGA, what are we GONNA DO?!!? jiojdfdkljs

Front 24

Supraspinatus Muscle
Function: Abduction-BOYFRIEND ARM

Actually with the Cory-Topanga disease (impingement of suprascapular nerve leading to loss of the "boyfriend arm", affecting the infra& supraspinatus) a lot has been covered.

Innervation of supraspinatus: Suprascapular nerve
Inserts: WHERE?

Back 24

Supraspinatus muscle inserts in superior facet greater tubercle of humerus. That makes sense the suprapinatus muscle is on very top...

Front 25

The motion is accomplished by which -spinatus muscle?

Back 25

The infraspinatus muscle assists in lateral rotation of arm.

Infraspinatus muscle ALSO inserts in GREATER tubercle.

Front 26

All of the four muscles of the rotator cuff (supraspinatus, infraspinatus, teres minor, subscapularis) INSERT in to the GREATER tubercle of the humerus, EXCEPT....

Back 26

The subscapularis muscle is the ONLY muscle of the rotator cuff that inserts into the Lesser tubercle of the humerus.

Front 27

Which muscle of the rotator cuff accomplishes this motion?

Back 27

Subscapularis muscle = medial rotation of arm.

The subscapularis muscle is actually the largest muscle of your rotator cuff & provides 50% of function. Indeed, sometimes you need all the muscle you can get to humble yourself and pray.

Here this man, has medially rotated his arms to pray, with all the strength the has.

Front 28

Innervation of all the Rotator Cuff Muscles

Supra & infraspinatus muscle = suprascapular nerve.
Teres MINOR = ___________ Nerve
Subscapularis Mucle= ___________________ Nerve, ________ cord of Brachial plexus.

Back 28

Supra & infraspinatus muscle = suprascapular nerve.
Subscapularis Mucle= lower subscapular Nerve of POSTERIOR cord of brachial plexus.

The only nerve that's not intuitive is teres minor= axillary nerve.

Front 29

What is function of Teres Major?

Back 29

Medial rotation of Arm = necessary to pray.

Again, PRAYING is a major part of Life.

It takes your majorly strong subscapularis muscle & the TERES MAJOR muscle to do so. Fitting.

Front 30

Where does Teres Major insert on humerus?

(Hint: As expected, since teres major is not part of the rotator cuff muscles it doesn't get to insert where all the other rotator cuff muscles gets to insert on humerus.)

Back 30

Teres major inserts on medial lip of intertubucular sulcus on anterior surface of humerus

See: You can't see insertion of teres major from the posterior view, b/c it inserts on the ANTERIOR surface of humerus!

Front 31

Teres major is innervated by ___________ nerve

Back 31

Teres major is innervated by inferior subscapular nerve

So the only nerve innervations not intuitive in shoulder region are

Teres minor = axillary nerve
Teres minor = inferior subscapular nerve

Front 32

All 4 MUSCLES of the rotator cuff (-spinatus muscl es, teres minor, subscapularis) are EXTRASYNOVIAL at and EXTERNAL to the glenohumeral joint.

Back 32

All 4 MUSCLES of the rotator cuff (-spinatus muscl es, teres minor, subscapularis) are EXTRASYNOVIAL at and EXTERNAL to the glenohumeral joint.

Note that the long head of the triceps brachii muscle passes _____________ to the teres major abut _____________ to the teres minor muscle, at it heads to the infraglenoid tubercle on the scapula.

Back 37

Note that the long head of the triceps brachii muscle passes POSTERIOR to the teres major abut ANTERIOR to the teres minor muscle, at it heads to the infraglenoid tubercle on the scapula.

Front 38

Fracture of the region here will lead to

Loss of WHAT Nerve Function
Loss of Innervation to WHAT muscle
Inability to .....

Back 38

Shown in the pic was the surgical neck of the humerus

Loss of AXILLARY NERVE
LOSS OF DELTOID MUSCLE
Inability to abduct arm to horizontal position & laterally rotate arm

(do u remember what rotator cuff muscles abducted & laterally rotate?)

Laterally rotate--infraspinatus
ABduct: supraspinatus

Front 39

All of the 3 muscles of the anterior compartment do FLEXION. When asked just for goodness sakes, say FLEXION as you would have said in Kindergarten, cause that's all we did with our biceps anyway.

BUT of the corachobrachials, brachialis and biceps brachii,which is responsible for flexion of ARM (not forearm)

Back 39

Corachobrachialis is responsible for flexion of ARM at glenohumeral joint. Heck it doesn't even go down the forearm!!

Probe is pointing to corachobrachialis with musculocutaneous nerve piercing it.

Front 40

So, as established, biceps brachii is responsible for flexion & supination.

Biceps brachii Inserts on the Radial or Ulnar Tuberosity?

Back 40

BICEPS BRACHII INSERTS ON THE RADIAL TUBEROSITY

Front 41

Brachialis muscle Inserts on the Radial or Ulnar Tuberosity?

Back 41

Brachialis muscle Inserts on the Ulnar Tuberosity.

Front 42

All muscles in forearm are INTERNAL to fasica.

The nerve supplying motor innervation to the anterior compartment of the arm is the MUSCULUTANEOUS nerve.

Which muscle does the MUSCULUTANEOUS nerve pierce?
Which muscle does it lie between?

Back 42

The MUSCULUTANEOUS nerve pierces the Coracho brachialis

& then lies b/w the other 2 muscles of the anterior compartment, brachialis & biceps brachii. Ain't hard. Next.

Front 43

Fill in nerve/ artery- Yup, again if you like! B/c it'll prob be on test.

Back 43

Front 44

The __________________ NERVE travels with the Brachial artery within the arm.

Back 44

The MEDIAN
NERVE travels with the Brachial artery within the arm.

Front 45

Shown here is profundaa brachii artery (should be running with the radial nerve) in the triangular interval.

What is the terminal branch of this artery called? And what does its terminal branch anastomose with?

Back 45

The terminal branch of the profundaa brachii artery is called: The radial collateral artery.

This kinda makes sense (I had a debate teacher who once told me - watch out who you hang out...b/c you'll start sounding like them)
Profundaa Brachii artery has been hanging with the radial nerve long enough...it has finally adopted its neighbor's name.

Radial Collateral Artery anastomoses with the Radial Recurrent Artery from the Radial Artery

Front 46

Note that the collateral always anastomes within its family.

Radial collateral Artery anastomoses with Radial Artery
Ulnar collateral artery anstomoses with Ulnar Artery

Back 46

Radial collateral Artery anastomoses with Radial Artery
Ulnar collateral artery anstomoses with Ulnar Artery

Front 47

Then the ulnar collateral always break "classes" when it anastomoses with the recurrents.

Back 47

Superior Ulnar collateral with the POSTERIOR ulnar recurrent

Inferior Ulnar collateral with the Anterior ulnar recurrent

Front 48

Posterior compartment: The triceps brachii & anconeus muscle are both working in extension of forearm.

What innervates this compartment?
What provides blood supply?

Back 48

What innervates this compartment? RADIAL nerve

What provides blood supply? PROFUNDA BRACHII
