Flashcard facts and information about the nervous system
Biology Bits stories are a great way for you to learn about biology a little bit at a time. We’ve broken down information into pieces that are very tiny—bite-sized biology cards. Cutting out the cards will let you organize them however you want, or use them as flashcards while you read.
This set of bits will teach you about the system that senses the world around you and controls your body: your nervous system. To learn more about the science behind your nerves, visit A Nervous Journey.
