Neuroscience is the scientific study of the nervous system.1 Traditionally‚ neuroscience has been seen as a branch of biology. However‚ it is currently an interdisciplinary science that collaborates with other fields such as chemistry‚ computer science‚ engineering‚ linguistics‚ mathematics‚ medicine‚ genetics‚ and allied disciplines including philosophy‚ physics‚ and psychology. It also exerts influence on other fields‚ such as neuroeducation2 and neurolaw. The term neurobiology is usually used

couple of centuries our knowledge of the nervous system has increased rapidly. As there were developments in the technology and techniques that are used to study the nervous system. Previous to the discovery of the neuron there were many rival theories about the arrangement of the nervous system. The two leading scientific groups leading the research labelled themselves as ‘The Reticularists’ and ‘The Neuronists’. The Reticularists theory was that ‘the nervous system consisted of a large network of tissue

PSYCHOLOGY • Comes from the root words : “psyche”‚ or mind‚ and “logos”‚ or study (Boring‚ 1950) • The scientific study of behavior and mental processes (Atkinson‚ 2000) • Is an objective and systematic study of how people behave and think • Its’ goals are to describe‚ explain‚ predict‚ and control behavior and mental processes. Psychologists are interested to find answers to questions like the following: ▪ What part of the brain is responsible for language? ▪ What

1. What is a neuron? o The individual nerve cell‚ comprised of the axon‚ dendrites‚ and cell body. 2. How many neurons in the nervous system? o 86 billion 3. Function of cell body‚ dendrites‚ and axons. o Cell body: Contains the nucleus and other major components. o Dendrites: Branch out from the cell body and receive messages from other neurons. o Axons: Carries messages away from the cell body to the dendrites. 4. Define polarization/depolarization. o Polarization: Resting state of neuron

Astrocytes are glial cells and have earned their name because of their star shaped figure. They make up a large population of cells in the brain and have a multitude of functions in the Central nervous system. The roles of the various types astrocytes include preserving‚ supporting‚ and mending nervous tissue. There are known to be three main kinds of astrocytes which are Protoplasmic‚ Fibrous‚ and Radial. Protoplasmic astrocytes happen in gray matter. They have a lesser amount of fibrils

The nervous system has a role in preserving the “fitness” of the internal environment. The nervous system coordinates and integrates blood volume‚ blood osmolality‚ blood pressure‚ and body temperature‚ among other regulate variables. In regards to hyponatremia‚ the nervous system is increasing blood pressure‚ decreasing

times required. The system within the body which assists to control and coordinate the functioning of all the systems is called the nervous system. The nervous system works alongside the endocrine system allowing communication and coordination between the many organs and systems within the human body. This allows them to function correctly‚ and have the ability to respond to stimuli when needed. The nervous system has two main systems within itself. These are the central nervous system known as CNS‚ and

tissue is found in ligaments‚ tendons‚ cartilage‚ and bone. Nervous tissue forms the nervous system‚ which is responsible for coordinating the activities and movements of your body through its network of nerves. Parts of the nervous system include the brain‚ spinal cord‚ and nerves that branch off of those two key parts. Nervous tissue consists of two kinds of nerve cells: Neurons are the basic structural unit of the nervous system. Each cell consists of the cell body‚ dendrites‚ and axon. Neuroglia

Both olfaction and gustation are chemosensory systems. Chemoreception means a molecule from the environment binds to a receptor on a cell’s surface. The receptor is shaped to receive and then respond when a specific type of molecule binds. This binding triggers a signal with the information about
