    The nervous system can be divided up into two distinct parts; the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and the spinal cord. It processes many different kinds of incoming sensory in formation. Most signals that stimulate muscles to contract and glands to secrete originate from the CNS. The PNS consists of all nervous tissue lying outside of the CNS. The PNS can be further divided into the autonomic (ANS) and the somatic (SNS) nervous systems

    animals have a nervous system. Neurons bundle together to form nerves. The purpose of the nervous system is to coordinate all activities of the body, and enables the body to respond and adapt to changes both inside and outside. The central nervous and the peripheral nervous systems are very similar but different at the same time. The CNS is made up of the brain and spinal cord and functions mainly to process information and determine the appropriate responses. The central nervous system receives sensory

    The Nervous System As early as the fourth century, philosophers around the world have researched the nerves in the human body. One Greek philosopher by the name Aristotle, believed that the nerves originated from the heart and that it was responsible for all the body’s movements and sensations (A History of The Nervous System). Although his theory was incorrect, it inspired other philosophers and researchers to take a closer look at the nerves in the body, thus paving the way for the discovery of
