Which ones of these are hard and which are easy to identify when dissecting a cat?

Question

superior vena cava, inferior vena cava, left and right brachiocephalic veins, left and right internal and external jugular veins, left and right subclavian veins, left and right axillary veins, left and right brachial veins, left and right renal veins, adrenolumbar vein either side, left and right femoral veins, left and right common iliac veins, left and right internal iliac veins, left and right external iliac veins, genital vein either side, gastrosplenic vein, coronary vein, intestinal vein, and hepatic portal vein.

Answer 1

The big ones are easy to identify and the small ones are hard.

Specifically

SVC, IVC easy
R+L brachiocephalic, jugulars, subclavians and axillary veins should be fairly easy
(subclavian veins? cats don't have clavicles ... they still call it subclavian?)

L+R brachial veins could be hard to find if you are inexperienced

R+L renal veins easy
adrenolumbar veins hard (small)

R+L femoral veins, common, internal and external iliac veins should be pretty easy

Genital veins are small and require careful dissection

Gastrosplenic and hepatic portal veins are midsized and should be easily seen but they are under a whole lot of stuff and so might be a bit harder to find

Coronary vein - don't know - never seen one myself ... cat's hearts are small things so this might be a bit tricky

Intestinal vein (?mesenteric veins) - should be fairly easy
