The intima

What is the innermost layer of the vein?

100
These veins run along the lateral calf and lie between the tibia and fibula
What are the Anterior Tibial Veins?
100
Longest vein in the body
What is the GSV?
100
Hydrostatic pressure at the heart 
What is zero?
100
Name two of the five characteristics of venous flow
What is 1) Spontaneity 

            2) Phasicity

            3) Ceases with valsalva maneuver 

            4) Augments with distal compression

             5) Competency 

200

This layer is thinner in veins than in arteries

What is the media?

200

Also known as the Fibular V

What is the Peroneal V?

200
This superficial vein extends off the Subclavian V
What is the Cephalic V?
200
The primary venous return mechanism 
What is the Calf Muscle Pump (aka calf veno-motor pump)?
200
This may be obstructed if continous flow is seen instead of phasic flow 
What is the site proximal to the Doppler interrogation?
300

The Vaso Vasorum is located in this layer

What is the adventitia?

300
A deep vein that empties into the Popliteal V
What is the Gastrocnemius V?
300
This vein runs in the antecubital fossa and connects the Basilic and Cephalic Veins
What is the Median Cubital V (aka Median Basilic V)?
300
The weight of column of blood pressing against the vessels from the heart level to the point of measurement 
What is hydrostatic pressure?
300
Loss of augmentation may indicate that there is an obstruction at this site
What is distal yo the site of Doppler interrogation?
400
This layer has unidirectional valves to prevent the back flow of blood
What is the intima?
400
Smallest component of the venous system; these are continuous with capillaries
What are venules?
400
The deep veins of the forearm that ascend medially
What are the Ulnar Veins?
400
During this phase of respiration, the diaphragm moves down causing the intra abdominal pressure to increase and the intra thoracic pressure to decrease 
What is inspiration?
400
Reverse venous flow of greater than ——- seconds is considered significant reflux
What is 1 second? (>.5 - 1 second is considered moderate venous reflux)
500
These are bicuspid
What are venous valves?
500
The communicating bridge between the deep and superficial veins
What is perforating veins?
500
The name given to the vein if the Small Saphenous V continues up the thigh and joins the GSV
What is the Vein of Giacomini or Intersaphenous V?
500
The difference between the intramural pressure and extrinsic pressure 
What is transmural pressure?
500
Perforator veins should not exceed this measurement in A/P
