Alright.. there aren't many review books to choose from, but I've know of the main ones.. My question is this... There is a lot of disagreement between the various texts/professors on the spinal levels of sympathetic innervation and distribution... e.g. Some will tell you that the heart is T1-T6 some say T1-T5......Some say the esophagus is T1-T6 and some say T2-T7... basically i keep on hearing conflicting answers from all directions. Does anyone know what the real answers are, not that there are "real" answers, but in regards to the boards coming up, does anyone know what book or website, or anything has the standard answers that we'll see on COMLEX????
