that dr. jack said:that's the other secret- there were some people in ISAC who hadn't taken anatomy before. of the two i know of off-hand, one is facilitating (very smart person and super nice), and the other is in the extra lucky position of having passed the class but not having to facilitate. watch out, this person is going to kick all our butts in biochem.
here's how i differentiated between nerves, arteries and veins:
nerves are whitish, luminous and you can see many fasicles running the length of the nerve when you look at the structure up-close. they are very cord-like and don't have any small wobbles, curves and the like. very strong, won't break as readily as blood vessels. get a nice penlight for the practical to see them. they will make a sound like a guitar string when plucked, but don't try to do that on the practical.
arteries are thicker, more meaty or muscular looking and can have some little curves and windiness in them. if one has been cut, the cross-section will be very round and you can appreciate the muscularity. they won't make any sound when plucked.
veins are flat and are often filled with old nasty brown blood (but not always!) in cross section they are very thin and aren't as nice and round as arteries.
if you want to come see the difference, i'll show you anytime on a cadaver.
Dr. Jack... Congrats on becoming our new Curric. Rep!!!!!!

PS cool advice, I've not heard of the Guitar method of differentiation b/t nn., aa. and vv. 😀

for luck.
