The stupidest nerve in the human body

Evolution can't slip into reverse and head back to the drawing board when it becomes apparent it's ballsed things up. If someone designed this, I give them 1 star out of 5 and want my money back.

Of course I learnt about the recurrent laryngeal nerve in the dissection room at medical school but I first appreciated its silliness when reading The Greatest Show on Earth by Richard Dawkins. It's just one of the many examples of how evolution has resulted in quite daft anatomy and physiology.

↓↓↓ More info and sources below ↓↓↓

If you were taking an engineering class in school and you turned in the human body for your final exam… you would get like, a C+. Or maybe a B- at best. That’s because the human body is full of design flaws. Except they aren’t really design flaws, because the human body wasn’t designed. It was evolved, and it is still evolving. And that means some of our parts don’t work as well as they could, they just work well enough. Here’s a rundown of a few of the human body’s biggest evolutionary fails!

The Terrible Design of the Human Spine | Corporis

We’re big-headed apes on two legs. Evolutionarily, that move to bipedalism left us with a spine that lends itself to injury. Recently, two new hypotheses have popped up that try to explain how more precise aspects of the spine and vertebraes’ shape influence injury.

What is in the Human Spine

Education video about What is in the Human Spine by Dr. Gary Simonds at Carilion Clinic.

Overweight and Back Pain Connection

Dr. Ronald Tolchin, Medical Director at Baptist Center for Spine Care, says back pain in overweight patients is relevant, because it deals with what the spine is designed to carry.

When you have an abnormal load, because you have increased weight, it goes forward and it pulls you forward. That strains the back muscles, so in order not to go forward and fall forward you work the back muscles to stand erect. But that puts more stress on the discs, and the bones, and the joints around the spine, he explains.

PREVIEW: Evolution of Spinal Cord Stimulation by Dr. Ricardo Vallejo, MD, FIPP

Dr. Vallejo discusses the evolution of spinal cord stimulation (SCS) over the past ten years. This includes how the theory of its method of action has changed and new data on high frequency stimulation.
