This isn’t new to science, it’s just one of the cool little quirks of human and comparative anatomy that more people should be aware of. Quick-quick background: autonomic (unconscious, involuntary) innervation of the body comes in two flavors, sympathetic and parasympathetic. Sympathetic nerve...
You need a tractable way to get started, to organize the things you’re learning, and to create a little structure for yourself. My recommendation: do a little project, with the emphasis onlittle. Anyone can do this, in any area of human activity. Maybe your project will be creating a ...
The employee evaluation system is to improve employee performance. While areas needing improvement must be reviewed, this should always be done in the spirit of discovering goals the employee can work toward. This holds true for reviewing successes as well. While praise for past achievements may be...
Before the start of the First World War, Britain relied heavily on imported grain from America for the production of bread. With the availability of grain limited by unrestricted German submarine warfare from January 1917, combined with a poorer than expected harvest in 1916 and the continued depl...
Dear Reader,Arriving in Chandler, Arizona two days ahead of our Casey Research Summit, I found myself with a bit of leisure time available.
Borrowed fromhttp://humanorgans.org/spinal-cord/ As a refresher, there’s nothing terribly special about thelumbosacral expansionof the spinal cord — you have one, labeled as the ‘lumbar enlargement’ in the above diagram. Where the spinal cord has adjacent limbs to run, it has more neuron...
or work in teams if they preferred. I’d also supply them with professional photographers to document everything they found, and a small army of research assistants to help them with library work and writing up. That wouldn’t be enough to declare the science of human anatomy a completed pr...
Sebastian computationally generated 1000s of different possible analysis models — permuting possible covariates and interactions — to get a size of the space ofpossibleresults. The question was this: how do human teams fill space? Does expertise in analysis mean outcomes cover a restricted, perhaps...
This is particularly useful when working out the consequences of an injury, like the spinal cord hemisection (Brown-Sequard syndrome) shown here in pink. The little human figure only shows the zone in which pain and temperature sensation are lost. There would also be losses of discriminative to...
And from comparisons with crocs and birds, we expect that sauropod cervical ribs had two sets of muscles inserting on them: a lateral set, and a ventral set. They’re the green lines, especially C and E, converging on the cervical rib in this diagram from our 2013 PeerJ paper: ...
