You must learn thenames, numbers (always use Roman numerals), and functions. There is noneed to learn a rhyme for whether they are motor or sensory. Knowing theirfunctions will tell you if they are motor or sensory. And the fact is that, whilesome are sensory only, all of the motor nerves have sensory proprioceptivefibers, despite the rhyme and the table in Marieb.60

Alzheimer’s TangleThis is aneurofibrillary "tangle"of Alzheimer's disease.The tangle appears aslong pink filaments inthe cytoplasm. Theyare composed ofcytoskeletalintermediate filaments.2121

Theseplaques are best seenwith a silver stain, asseen here in a casewith many plaques ofvarying size.2222
