CENTRAL NERVOUS SYSTEM The Brain -recap * The brain receives signals from inside and outside the body. * It keeps the basic‚ body functions such as heart beat rate‚ breathing rate and temperature control ticking over‚ without us having to think about it. * It also allows us to decide to do things like running and walking and many more complex tasks. It is where our personalities and moods and emotions come from. * The brain of a human being makes up about one-fiftieth of

The nervous system is the most important system in the body. It transmits impulses to and from the brain. Disruption of the nerve cells and fibers that transmit the messages severely impairs the body’s ability to carry out complex function. Once a disruption occurs‚ one may never recover and neurological function will steadily degrade. Multiple Sclerosis is a disease that disrupts this network. Multiple Sclerosis (MS) is the most common disabling neurological disease in young adults between 20 and

Axia College Material Appendix G The DSM-IV The DSM-IV is an important tool for clinicians. It provides a standard for diagnoses to be standardized across psychology; however‚ the DSM-IV is not as precise for diagnosing personality disorders as some psychologists would like. Give an example of each of the following problems identified in your readings and explain how these problems could negatively affect a diagnosis. 1. Some criteria used for reaching a diagnosis cannot be observed

Inside our brain‚ there is this system called the human nervous system. There are two types of nervous systems: the peripheral and central nervous systems. The peripheral nervous system includes the nerves connecting the central nervous system to the rest of the body. It has two subdivisions: somatic nervous system and autonomic nervous system. Somatic nervous system controls skeletal muscles and interacts with the external environment. An example is walking through a park. You are using your motor

The nervous system is made up of millions of neurons and interconnected nerves that are comparable to a wiring system. The nervous system is composed of the central nervous system (CNS) and the peripheral nervous system (PNS). The nervous system functions like a corporate giant. The CEO is the leader in the CNS and the officers and delegates are the PNS. The CNS gives the commands and the PNS follows the commands. The Central Nervous System The central nervous system (CNS) is

of the brain and spinal cord. Neurones are found throughout the body with the majority found in the central nervous system. Neurones are specialized to process information in the body. Neurones convey this information to one another through the stimulation of a detector neurone. This causing a brief change in the electrochemical gradient resulting in the neurone moving away from its resting potential. This is known as an action potential. Once initiated the action potential travels the length of
