Dear WW: My mother didn't want any wimps in the family. And when she told me to do something, I did it.
Dear SM: The lungs don't to anything until the diaphragm and ribs move. And the diaphragm muscles and rib muscles are controlled by nerves coming from the spinal cord. Your vet was not speaking as he would have to another vet.

and continuing the anatomy lesson, re:The lungs don't to anything until the diaphragm and ribs move. And the diaphragm muscles and rib muscles are controlled by nerves coming from the spinal cord
breathing is controled by the base of the brain, sometime called the reptilian part (since it contains many of the same funtions that can be found in reptile brains.) and breathing is one of them.. you don't have to remember to breath, a small part of your brain does that for you.. and as higher functions (thought, image processing, etc) go, the only thing left is the reptilian part.. and you keep breathing. then as damaged lungs bring less air in, and damaged hearts move less blood, and damaged kidneys let toxins accumulated, and damage livers fail to clean out old and damaged red blood cells, less and less oxoginated blood gets to the brain, and it falters.. and finally fails to send the signal to the diaphragm to contract..

Dear of troy: Reptiles can be amazing. When I was about ten, my father brought home a snapping turtle, with a shell the size of a manhole cover. He shot it to keep his bird dog from getting bitten. Bird dogs will in some cases point turtles. His full choke 12 ga. shotgun had made a hole in turtle's head the size of a baseball. But for over a week if you kicked the turtle's legs, they would retract. Dear Hyla: If you have not already read it, you would enjoy "Eggs for Agassiz" written by a Middleboro school teacher long ago. He knew Agassiz was writing a book on turtle embryology, and desperately wanted some freshly laid snapping turtle eggs to study. He had quite an adventure getting them to Cambridge on time. The original article was in ATLANTIC. and is cited in the very short version to which URL is: http://www.uh.edu/engines/epi1071.htm This is one of a series, all of which are very good reading.

At the risk of self-YARTing, I'll repost my link to http://www.miketheheadlesschicken.org. He lived for 18 months after the ax blow that was designed to kill him only took off his head *above* the brain stem (which controls a chicken's reflex actions). He had to be fed by eyedropper, and they had to clear his esophagus periodically - but he seems to have been quite an attraction there for a while in the 40s.
