The nervous system is made up of all the nervous tissue in the body. This organ system forms a network of communication and coordination between all parts of the body. It plays an important role in daily activities such as breathing, walking and even blinking. It is made up of nervous tissues to receive and transmit stimuli to nerve centers and initiate response. Neurons are nerve cells that transmit signals from one part of the body to another. With damage to the nervous system the body would not be able to function properly. The body must be well looked after to ensure proper regulation. The two anatomical divisions that work side by side to help regulate the nervous system are the central and peripheral nervous systems. According to the seventh edition of Campbell's biology book, the nervous system is the most intricately organized data processing system on earth. It is a complex collection of nerves and specialized cells. The three interconnected functions of the nervous system are sensory input, integration, and motor output. Sensory input is the conduction of signals from sensory receptors to the central nervous system. Integration is the analysis and interpretation of the sensory signal and the formulation of appropriate responses. Motor output function is the conduction of signals from integration centers to effector cells, which execute the body's responses. The central nervous system (CNS) consists of the brain and spinal cord. The brain and spinal cord act as a collection section for nerve impulses. With damage to the peripheral nervous system, the central nervous system would not be able to interpret stimuli because it would not be able to receive them.
