I don't really believe in astronomy, except as a complicated description of part of the course of human and possibly animal sensation. I apply my perspective not merely to space but also to time. In time the world will cool and everything will die; but that is a long time off still ...
Second, this case, a few other odd things we’ve found in the lab over the years, and other recently-reported discoveries in human anatomy have caused me to wonder: could we formulate predictive maxims to help guide future discoveries in human anatomy, or in anatomy full stop? I think so...
One thing you did have at that stage was a reasonably complete peripheral nervous system. The nerve cell bodies in and near your central nervous system sent out axons into the rest of your body, including your extremities. Many of these axons did not persist; they failed to find innervation ...
And the ribcage is also a projection area, on which a video is played that shows the internal organs and how they work. With a voice-over that explains the actions in simple terms, the principle of the avian-style unidirectional lung and the air sacs is explained (albeit with a small ...
Images and figures from Schachner et al. (2013b) appear here courtesy of Emma Schachner (website), who kindly offered to let me look under the hood before the paper came out. She also created acool videoshowing the 3D lung anatomy ofV. exanthematicus. Thanks, Emma, and congratulations!
Borrowed from http://humanorgans.org/spinal-cord/ * Some relevant hard-core anatomy for the curious: sauropods have neural canals in their tail vertebrae, and usually far down their tails, too. But that doesn’t mean much–you have neural canals to the bottom half of your sacrum, but yo...
I was interested in skeletal illustrations I have seen ofTyrannosaurus rex, which compare the completeness of various specimens by showing the actual bones included by coloring them red. A 2005 study ofApatosaurusby Upchurch et. al. examined eleven of the most completeApatosaurusindividuals, and I ...
Borrowed fromhttp://humanorgans.org/spinal-cord/ Humans have these, too, in our lower cervical vertebrae to run our forelimbs, and in our lower thoracic vertebrae to run our hindlimbs. Recall that the segmental anatomy of the adult human spinal cord corresponds increasingly poorly to the verte...
(I have much more disgusting photos than this one, but it wouldn’t be tasteful to show them.) Anyway, I abandoned my initial plan of dissecting the organs out, and basically just removed and discarded them. I’ve actually had shamefully little experience with dead animals, so I don’t ...
“starburst” near their target organs, making identification almost impossible. Do not waste your time trying to memorize any particular branching sequence. Instead, concentrate on matching the arteries to their targets; you will discover the identities of the branches by seeing where they are going...
