How we cite our quotes: All quotations are from Young Frankenstein.
Quote #1
FREDERICK: If we look at the base of a brain which has just been removed from the skull, there's very little of the midbrain we can actually see.
While we'd never recommend using Young Frankenstein to help you cram for your A&P final, there's an awful lot of accurate scientific talk at the beginning of the movie. It helps show us that Frederick's character is very serious and definitely not crazy at this point.
Quote #2
FREDERICK: Reflex movements are those which are made independently of the will but are carried out along pathways which pass between the peripheral nervous system and the central nervous system.
This quote is a discussion of fate and free will disguised as science. While Frederick, on the surface, is talking about reflex movements, he could also be talking about his journey from respectable man of science to mad scientist. It happens independently of his will. It's his fate.
Quote #3
FREDERICK: In spite of our mechanical magnificence, if it were not for this continuous stream of motor impulses we would collapse like a bunch of broccoli!
For the reanimation of the monster to be even more dramatic, it must first be believed to be impossible, as it seems here at the beginning of the movie.
