cephalic vs. basilic vein?

[HelpingHand]

Any tips on accurately distinguishing the two in the brachium and antebrachium?

In anatomical position, the cephalic vein is more lateral. That's really about it. They're pretty hard to miss.

+1. Our cadaver didn't even have a cephalic vein.🙄

as milkman mentioned, cephalic is always going to be the more lateral/radial one. If you're still having trouble, just find the cubital fossa, find the median cubital vein, and work your way up...

Our anat professor told us that the basilic v. is in the BASE of the arm--the part thats on the bottom when you flex your biceps and if you don't have muscles is a huge sac of flab.

Haven't gotten to the basilic yet, but the cephalic is extremely prominent in the deltoid region. That said, I don't remember seeing the basilic at all (and based on above I shouldn't have). The cephalic branches, I believe, at the acromion so you can always follow it back to there and look for the branches.

Basilic is going to go straight up the medial side of the arm and become the axilary vein......it is very easy to see the (lateral) cephalic vein draining into it.


Speaking of weird anatomy variations.....we did a dissection on an elderly woman who had no brachial artery....her artery bifurcated from axillary artery straight into "radial" and "ulnar" arteries just inferior to the brachial plexus. Very interesting.....

Hold your arm out to the side, palm out.

The basilic is the 'basement' while the cephalic is the 'ceiling.'

Interesting indeed. Now, I know the ideal goal is to have a decent specimen of everything needing to be identified in your cadaver so at least some of the practical questions will use your table, but has anyone found that their body just doesn't have a whole lot of good examples to look at? I feel like I'm always having to go over to other tables in order to examine their anatomy because ours is, well, lacking.

Our brachial plexus didn't have the "M."

But that's neither here nor there since we're talking about veins.

Same here! we got an overweight lady and there's just so much fat. My lab partners and I have found it easier to do the bare minumum on our body and then go around to the other bodies. The weird thing is that out of the whole class, we've had the best brachial plexus and upper extremity vasculature and innervations, so that part has been going well😀

Be very careful doing that. The anatomy professors at my school take pleasure at "finishing" dissections for the practical. The most famous case happened two years ago when a group only dissected one side. Let's just say that there was a tiny window dissected at the wrist just down to the tendons and a tendon tagged on the practical.

If they cover up the forearm and most of the arm (like they did on our practical), it's also good to remember that the cephalic will run between the deltoid and pec. major (deltopectoral triangle).
