Radios slices of a human body: 3mm thick

about https://news.ycombinator.com/item?id=29705819 Was this recently discovered new muscle visible on the visible Human project cross-sections?

I am quite sure you can see it in this and adjecent slices. https://data.lhncbc.nlm.nih.gov/public/Visible-Human/Additio...

compare this to the muscle marked C in this image from the original paper https://ars.els-cdn.com/content/image/1-s2.0-S09409602210020...

Brilliant!! Thanks for doing the hard work, I was too afraid to look at the slices.. Had you seen this 6 month ago, you would have made a major scientific discovery. I hope this will inspire you to look at other non-yet well classified anatomical features. noob question: do you know what different imaging technologies are used between your two links? Again thank you for your comment I wasn't expecting that someone would actually do the investigation!

The only other recent anatomical discovery I recall (not my field so there are probably many others), is a new kind of cell in the human eye, IIRC a full layer of one new cell type, traversing the eye vertically, but the layer is only 1 cell wide in thickness (hence why it has been discovered recently by accident) https://www.aaojournal.org/article/S0161-6420(13)00020-1/ful... discovery seems like a much harder challenge for you. Although this muscle give hope that there are non-too small features left to discover in our own bodies. https://www.google.com/search?q=Human+Corneal+Anatomy+Redefi...

edit how do you navigate the dataset? I don't see an online version only download and the png section can't be navigated from prev slice to next slice with keyboard arrows or GUI, is there a link to download everything as a folder of images instead of each image individually? plz if so share the link

the imaging tech in both cases is simply a picture of a thin slice of a frozen body. You can navigate the pictures here: https://www.nlm.nih.gov/databases/download/vhp.html

I looked in Additional-Head-Images/cryo/jpeg/fullSize/axial

I think there was also a discovery of some muscle around the knee a few years ago.

Thank u

But I don't understand, it is well known that (every?) bones are preserved between mammal species and that they only have morphisms (e.g' a bat hands.. completely crazy) But aren't muscles preserved between species as well? Not as much?
