The Nervous System Neuroscience is critical in understanding addiction because it’s how our different body parts communicate. Psychoactive drugs affect the brain as a result of the processes of the nervous system as it receives senses, is able to transmit because it's interconnected, and initiates responses. The Central Nervous System is comprised of the Brain and the Spinal Cord. The nervous system is in essence a biological information highway, is the controller of all the biological functions and movement in the body, and can also receive information and interpret it. This is done through electrical signals which are used in the nervous system. It consists of the Central Nervous System as the processing area and is made up of the brain and spinal cord. While the Peripheral Nervous System detects and sends electrical impulses that are used in the nervous system. The nervous system is the part of the body that coordinates the actions and transmits signals between different parts of the body. In most species it consists of two parts, the Central Nervous System and peripheral nervous system. The Central Nervous System contains the brain and spinal cord. The Peripheral Nervous System consists mainly of nerves that connect the Central Nervous System to all the other parts of the body such as muscles and organs. The Peripheral Nervous System also includes the enteric nervous system, a somewhat independent part of the nervous system whose function is to control the gastrointestinal system. The nervous system is defined by the presence of a special type of cell, called the neuron. Neurons send signals with rapid precision to other cells with special structures that allow them to accomplish this task. Sensory neurons carry impulses or electrochemical signals to the interneurons of the brain. The interneurons interpret these impulses while the motor neurons carry
