The Nervous System is one of the most important and complex system in the human body, because it works as the main control center. It regulates the sensory, integrative and motor function of the body. Everything we do, feel or think is directly linked to the Nervous System. An error in any of these functions could bring negatives consequences such as degenerative diseases later in life.
The Nervous System can be divided into two different categories, the central nervous system (CNS), and the peripheral nervous system (PNS). The CNS is made up of the brain and spinal cord, and the PNS is made up of the rest of the nerves that connect the brain and spinal cord to the rest of the body. The major functions of the nervous system are sensory, integrative and motor function. The sensory function of the nervous system receives sensory receptors by detecting changes inside and outside of the body. The integrative function processes the information. Motor nerves convey information from the CNS to the body, and make the necessary response (Herlihy & Macbius, 2000).
The nervous system is composed of two tissue cells: neurons, which allow the functioning of reaction to physical and chemical changes that may occur through the lifespan, and the neuroglia cells, that give support and protection to neurons (Herlihy & Macbius, 2000). In order to better understand how the nervous system works, it is essential to know how neurons work, since they are the most important tools for transmitting information.
All neurons have a cell body containing: the nucleus which is important for the cell life. Another part of neurons include dendrites, which receive information from other neurons. Below the dendrites is the axon, and its major function is to send...

The body is controlled down to its core by the central nervous system. The central nervous system consists of the brain and the spinal cord. Both of these are made up by white and gray matter. The brain which has gray matter on the outside and white matter on the inside is responsible for processing the information that it receives from the nerves and spinal cord, sending out responses, and coordinating motor functions. The spinal cord is opposite of the brain and has gray matter on the inside and white on the out. The spinal cord conducts the information or messages it receives from the brain to the body and sends its “research” back to the brain for processing.

A bunch of nerves put together is called the Nervous system. The Nervous system helps with body coordination and provides sensory information about external problems. The nervous system controls the brain, spinal cord, sense organs, etc. Without our nervous system, we would not be able to function, since
Alzheimer’s disease is a complex illness that affects the brain tissue directly and undergoes gradual memory and behavioral changes which makes it difficult to diagnose. It is known to be the most common form of dementia and is irreversible. Over four million older Americans have Alzheimer’s, and that number is expected to triple in the next twenty years as more people live into their eighties and nineties. (Johnson, 1989). There is still no cure for Alzheimer’s but throughout the past few years a lot of progress has been made.

In this day and age, it seems as though almost everyone has experience a loved one taken away form a very serious disease known as Alzheimer’s disease. Alzheimer’s disease is unbelievably devastating for everyone affected by it. This disease is causing major economical problems such as less occupancy in the nursing homes, and hospitals due to the rising population of elderly men and women being diagnosed with it everyday. Because there is not yet a cure for this disease and the percent of the population being diagnosed keeps rapidly rising, more time and money needs to go towards Alzheimer’s research.
Alzheimer's Disease Introduction to Alzheimer's Alzheimer's disease is a progressive, degenerative disease of the brain. It was first described by the German neuropathologist Alois Alzheimer (1864-1915). in 1905. This disease worsens with advancing age, although there is no evidence. that it is caused by the aging process.
Alzheimer’s disease, named after Dr. Alois Alzheimer, is a disease that is on the rise in America and the rest of the world. People should learn as much as they want about this disease, because as you age, your chances of becoming an Alzheimer’s Disease, or AD, patient increases. It is estimated that approximately 3 percent of Americans between the ages of 65 and 74 have the illness, and more than half of all people over age 85 have the ailment.
Neurons and glia (cells that support neurons) are specialized cells for electrical signaling over long distances. Understanding neuronal structure is important for understanding neuronal function.
Our nervous system interacts with every other system in your body. The endocrine system works with our brain and central nervous system, to control the creation of specific hormones and enzymes. The digestive and excretory systems work with the nervous system in a conscious and unconscious ways. We can't tell our stomach where the food goes after we ingested it. The body is programed to function voluntarily and
The brain consists of both neurons and glia cells. The neurons, which are cells housed in a cell body called a Soma, have branches which extend from them, referred to as dendrites. From these dendrites extend axons which send and receive impulses, ending at junction points called synapses. It is at these synapse points that the transfer of information takes place.
The brain and spinal cord make up the central nervous system. The brain doesn't just control your organs, but also can think and remember. That part of the brain is called the mind.
It is the idea that the mind and body are not separate entities. Rather, they are intricately connected, interacting with each other in many ways. The body's three main regulatory systems are the central nervous system (which includes the brain), the endocrine system (which produces hormones), and the immune system. These three systems work together and affect one another. Researchers who study the mind-body connection examine these interactions, and are particularly interested in the effects of emotions and thoughts on physical health.
Nervous system is one of the major organ systems that is responsible for the coordination of biological activities inside the body through cells called neurons. It is composed of the brain and spinal cord which are surrounded by protective layers of bone and membrane tissues called meninges. There are two major divisions in the nervous system; first one is the central nervous system (CNS) and the other being the peripheral nervous system (PNS). The CNS is composed of the brain, spinal cord, and retina while the PNS includes the sensory neurons, ganglia, and connecting neurons. The nervous system applies control using nerves; almost as if sending a message by a telephone. The nervous system is fast due to its electrical nature. The nerve cells in this system are connected with each other in a complex manner where the neural pathways would be possible. Neural
The nervous system’s main function is to coordinate all of the activities in the body. The main organs are the cerebellum, which controls and coordinates movement. The cerebrum, is the center for conscious thought, learning, and memory. The last main organ is the brain stem. The brain stem keeps the automatic systems in your body working. Problems of the nervous system include, epilepsy, Alzheimer’s, and multiple sclerosis. You can care for your nervous system by wearing a seatbelt, wearing a helmet, and by not using drugs or alcohol. Something very confusing about the nervous system is that the left side of human brain controls the right side of the body and the right side of the brain controls the left side of the body!
