rectum
According to Sumida, what is the “shameful” artery that goes to the “shameful” place?

Internal iliac artery
What is the “old umbilical artery”?
the end of your internal iliac artery

umbilical vein
Comparing fetal hemoglobin and adult hemoglobin, what is fetal hemoglobin better at doing?
better at picking up oxygen than adult hemoglobin
What artery in the leg is one of the “exceptions” - meaning it’s close to the surface instead of deep like most other arteries?
femoral artery
What consists of the femoral triangle?
Sartorius (lateral)
Adductor longus (medial)
Inguinal ligament
What goes through the femoral triangle?
Femoral nerve
Femoral artery
Femoral vein
Lymphatics
The external iliac artery becomes what artery?
femoral artery
Branching from the femoral artery are 3 vessels. What are they?
Profunda femoris
Medial femoral circumflex
Lateral femoral circumflex
The femoral artery turns into 2 things. What are they?
Popliteal Saphenous AA (anterior accessory)
What arises from the profunda femoris?
Descending branch of lateral femoral circumflex artery
What is the “kneepit” called?
Popliteal fossa
The popliteal turns into…
Posterior Tibial artery
Anterior Tibial artery
Peroneal artery
The anterior tibial artery turns into __________, which turns into _____________.
Dorsalis pedis artery
Deep plantar artery
TRUE OR FALSE:
the pressure in the subclavian is higher than any artery in the leg.
true
When does the subclavian change names? What is the name?
Up until clavicle
Axillary artery
What does the axillary artery turn into?
Brachial artery
3 major branches of subclavian:
Vertebral artery
Thyrocervical trunk
Internal thoracic artery
What is the first branch of the subclavian? What does it run through? What does it supply?
Vertebral artery
Runs through transverse foramen of all 7 cervical vertebrae & runs through foramen magnum of skull to
Supplies underside of brain
The thyrocervical trunk travels in what direction?
superiorly
The internal thoracic trunk travels in what direction?
inferiorly
The internal thoracic artery runs just inside what?
rib cage
The axillary artery has how many branches? They are organized relative to what?
6
relative to pectoralis minor muscles
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
Which vessels of the arm are similar in design and function to the medial and lateral femoral circumflex arteries?
anterior humeral circumflex artery
posterior humeral circumflex artery
Proximal to distal in the arm (subclavian region):
Vertebral artery
Thyrocervical
Internal thoarcic
Proximal to distal in the arm (axillary region):
supreme thoracic artery thoracoacromial artery lateral thoracic artery subscapular artery anterior and posterior humeral circumflex arteries
What is the anastomosis of Internal Thoracic artery that links to the hip?
External iliac artery
The brachial artery branches into 2 arteries. What are they?
Ulnar artery
Radial artery
The ulnar artery carries on and turns into what?
common interosseous artery
Sumida’s words…
“What’s the name of that tough tough tough tough tough membrane between the bones?”
interosseous membrane
The common interosseous artery branches into what?
Anterior interosseous artery
Posterior interosseous artery
The radial and ulnar arteries turn into…
superficial palmar arch
*carries on later to supply each of the digits (common palmar digital artery)
What did Sumida have on his wrist that he needed to get removed?
Ganglion cyst
The cyst was not on Sumida’s muscle tendon like he thought it was; what was it on?
Radial artery
*it was squeezing it shut
What is the anastomosis of the artery on which Sumida found a cyst?
Ulnar artery
Generally, veins are parallel to arteries. What is the exception?
the base of the hepatic portal system
and the superior vena cava is not RIGHT next to aorta
3 layers of meninges:
Dura mater
Arachnoid mater
Pia mater
The dura mater encloses some “sloshy” spaces. What are they called?
Venus sinuses of the skull
The venus sinuses eventually dump into the vein that exits the hole, which is…
Jugular vein
* goes through jugular foramen
At the top of the fall cerebri and the bottom are two parallel tubes. They are called…
superior sagittal sinus
inferior sagittal sinus
*straight sinus is where they connect
After leaving the superior/inferior sagittal sinuses, the blood goes to the right or left in the back of the head into the…
transverse sinus
After the transverse sinus, there’s a curvy sinus that goes to the petrosal sinus. Is it..
the sigmoid sinus
After the petrosal sinus, it dumps into the…
cavernous sinus
*note: cavernous comes from the spongy tissue of the penis; “penis tissue of the brain”
What was the main aortic arch derived from number 3?
carotid arteries
external = face
internal = brain
Carotid goes into brain through…
carotid canal
The reason the carotid choke hold doesn’t work right away is because there’s another protective blood vessel going into the skull. It is the…
vertebral artery
first branch of subclavian
The right and left vertebral arteries come into the skull via what opening?
Together they form into what?
foramen magnum
basilar artery
The basilar artery as well as the R and L carotid arteries feed into a little “loop” called…
Circulosus Arteriosus Cerebri
The tributaries of the circulosus arteriosus cerebri are…
- R and L internal Carotid arteries
- Basilar artery formed from R and L vertebral arteries
