relative to pectoralis minor muscles

30
Q

Axillary artery branches:

“1 - 2 - 3”
1 before pec. minor = supreme thoracic artery
2 deep to pec minor = thoracoacromial artery and lateral thoracic artery
3 beyond pec minor = anterior humeral circumflex artery, posterior humeral circumflex artery, and subscapular artery

common interosseous artery

37
Q

Posterior interosseous artery

39
Q

The radial and ulnar arteries turn into…

A

superficial palmar arch

*carries on later to supply each of the digits (common palmar digital artery)

40
Q

What did Sumida have on his wrist that he needed to get removed?

A

Ganglion cyst

41
Q

The cyst was not on Sumida’s muscle tendon like he thought it was; what was it on?

A

Radial artery

*it was squeezing it shut

42

What is the anastomosis of the artery on which Sumida found a cyst?

A

Ulnar artery

43
Q

Generally, veins are parallel to arteries. What is the exception?

A

the base of the hepatic portal system

and the superior vena cava is not RIGHT next to aorta

46
Q

The venus sinuses eventually dump into the vein that exits the hole, which is…

A

Jugular vein

* goes through jugular foramen

47
Q

At the top of the fall cerebri and the bottom are two parallel tubes. They are called…

After the transverse sinus, there’s a curvy sinus that goes to the petrosal sinus. Is it..

A

the sigmoid sinus

50
Q

After the petrosal sinus, it dumps into the…
