Chapter 43, Problem 3TY
Summary Introduction
Introduction: Nervous system is a system in the body that helps in the transfer of information from one part to another. The body parts communicate with each other and with the external environment through the nervous system. Brain is the most important organ in the nervous system. Brain guides all the other organs in the body. Humans have the most complex brain.
