Finally got this book after ordering about a month ago! Anyways, is the book any good. I know some books like Barrons are usefull for PAT, what is this book most usefull for! Also, what section best corresponds to the DAT (strengthwise)! Also had a bio question, It might be a stupid one but its good to know: Where are achetocholine produced? --I know acetochoilinasterase are produced in the liver, and i know vagus nerve produces some by the right atria to slow down the heart rate, but is there any other place where they are produced?
