he nervous system is the communication network of the body. It consists of a complex collection of nerves and specialized cells‚ called neurons‚ that transmit messages across the different parts of the body in order for it to function and react correctly. They are known as the building blocks of the nervous system. Structurally they have long extensions that extend out from the cell body. There are two types of these extensions; dendrites‚ which are extensions of the neurons that receive signals

LEVELS OF ORGANIZATION OF NERVOURS SYSTEM: NEURONS: * STRUCTURE AND FUNCTION: Specialized cell transmitting nerve impulses; a nerve cell. Neurons have specialized projections called dendrites and axons. Dendrites bring information to the cell body and axons take information away from the cell body. Neurons communicate with each other through an electrochemical process. Information is transmitted to the receiving cell at junctions via chemical messengers called neurotransmitters. At this juncture

The principal structure of the digestive system is an irregular tube‚ open at both ends‚ called the alimentary (al-i-MEN-tar-ee) canal or the gastrointestinal (GI) tract. In the adult‚ this hollow tube is about 9 meters (29 feet) long Think of the tube as a passageway that extends through the body like a hallway through a building. Food must be broken down or digested and then absorbed through the walls of the digestive tube before it can actually enter the body and be used by cells The teeth

Tissue - The nervous system includes all nervous tissue in the body -Neural tissue contains two types of cells: 1) neurons (10% of all neurons‚ conduct nerve impulses) 2) neuroglia (support neurons) -We have 100 billion neurons -Organs of the nervous system: brain‚ spinal cord‚ sensory receptors of sense organs (eyes‚ ears‚ etc.)‚ and nerves (connects the nervous system with other systems‚ bundle of neurons that relay information) -Functions of the nervous system: 1) sensory input- everything coming

This assignment called for me to pick three out of four sensory experiments to conduct and then record my reaction to each experiment. The three experiments I chose to conduct are number one- the sandpaper experiment‚ number three- the index cards and flashlight experiment and number four- the water in bowls experiment. While conducting each of these three experiments I was surprised by the results of each of them. Experiment Number One: I rubbed my finger on the piece of coarse sandpaper and

THE CENTRAL NERVOUS SYSTEM Every behavior begins with biology. Our behaviors‚ as well as our thoughts and feelings‚ are produced by the actions of our brains‚ nerves‚ muscles‚ and glands. In this chapter we will begin our journey into the world of psychology by considering the biological makeup of the human being‚ including the most remarkable of human organs—the brain. We’ll consider the structure of the brain and also the methods that psychologists use to study the brain and to understand how it
