#learnthis 💜 ・・・ #Repost @anatomytrainsofficial (@get_repost) ・・・ Edit: There has been a lot curiosity about the sciatic nerve / piriformis. The best way get answers to ‘see for yourself’ in one of our dissection courses. 2-day course is coming up in Boulder, CO, May 18-19. Link in our bio for more info. From Tom Myers: My understanding was that the ‘piriformis syndrome’ had been found to be another red herring, like 'bulging discs’. Tried in the arena of research and found wanting. ・・・ What I find so interesting about this picture is how the nervous system is so clearly pulled headward (cephalad). See how all the nerves angle up toward the head? They would have been straight in their first evolutionary expression, but now they are pulled to the ‘pine bough’ angle. ・・・ In the same vein, the spinal cord itself ends under the bit of spine in the low mid back. Everything you see in the window in the low back and the window through the sacrum is all spinal nerves, the cauda equina or horse’s tail. Your whole central nervous system is pulled up, folded up into your skull and giving short shrift to the bottom part of the spine. ・・・ In any case, it’s not a ’tight’ piriformis that presses on the sciatic nerve - we’re better designed than that - but a twist or torsion in the pelvis can position the nerve in a not-happy place. ・・・ PC: Gunther Von Hagens Bodyworlds . . . . . #anatomytrains #bodyworlds #tommyers #sciaticnerve #anatomy #piriformis #neverstoplearning #sensualiq #sensualintelligence https://www.instagram.com/p/BusJLVcHyeo/?utm_source=ig_tumblr_share&igshid=gb0mdbglgosr
