[Shiny]

Hello,

I'm currently working on a 3D conceptual rendering of a sperm cell and I found that most illustrations that are out there show the thickening behind the 'head' as a bunch of toruses, sometimes a thick spiral.



From schematic cross-sections I know it supposed to be mitochondria and to my simple mind those suppose to be a bean/capsule shaped objects. So are they just very closely wound around the center ? Also amazingly 99% percent of the illustrations get the proportions completely wrong (the "head" is a different shape, the thickening in question is exaggerated, very often the 'head' is symmetrical as in fact it's flat ... etc).



I know that as we get closer and closer to the molecular level things aren't perfectly smooth, but I'd still like to get the thing to look properly and as close to reality as possible.

This might be a silly question to some of you, but I'm really puzzled why something depicted so often in various publications isn't shown correctly.
