The cervical spinal cord
By removing the rear arches of the neck (cervical) vertebra and the fibrous covering (dura) over the spinal cord one sees the cervical spinal cord and its nerves. The blood vessels nourishing the cord and vertebral column and the origin of the cord from the brain are clearly shown.

Illustration of Melibe leonina. As someone who can be a bit awkward a times, I’ve decided the sea slug Melibe will be my new power animal. I’m clumsy, constantly bumping into things, equally bad at all sports, and catch roughly 2% of things that are tossed to me. I don’t exactly always feel li…
If you thought the post on twins sharing consciousness was awesome, wait until you hear this.
A 44-year-old French man one day went to the trip to the doctor’s because he felt a pain in his left leg. He’s a married man with two kids and a steady job.
Doctor’s found that he had hydrocephalus as a child (when your brain is filled with fluids) so they decided to run some brain scans.
What they found was that the majority of his head was filled with fluid. Over time, the buildup caused his lateral ventricles to swell so much that his brain had been flattened to a thin sheet.
Doctors estimated that his brain mass had been reduced by at most 70%, affecting the areas in charge of motion, language, emotion, and, well, everything.
Shockingly, he was fine. While his IQ was only 75, he wasn’t mentally challenged. He held a steady job, raised a family, and didn’t have trouble interacting with others.
Over time, his brain had adapted to all that pressure, and even though he had fewer neurons that most, Jacques was still a fully functional human being.
The doctors drained the fluid and while his brain is much smaller now, he is still a healthy individual with a normal life.
"The Sad Clown" by Igor Ryabov This crab spider bears a resemblance to the ‘clown’ character in Stephen King’s 1990 hit-film ‘It.’ May be therefore Igor named it sad clown. ‘Crab Spider’ belongs to the thomisidae family, also known as "six eyed crab spider" as it bears markings near its eyes that looks like real eyes and also due to the skeleton like markings on its back.

nobody seems to care much about these guys, yet your arm would swell up without them — there’s just enough net fluid leak from capillaries to cause problems in the absence of another set of pipes to return that transudate to the circulatory system
