¶ … Nervous System
The central nervous system is one of the two parts of the nervous system, which also comprises the peripheral nervous system. These two systems have different roles, functions, and location in the body, which contributes to their significant differences. The central nervous system incorporates brain nerves and spinal cord whereas all the other nerves in the human body are part of the peripheral nervous system. Since it contains brain nerves and spinal cord, the central nervous system is safely guarded in the spine's vertebral canal and the skull. Consequently, the central nervous system is one of the most important parts of the human body that is crucial to the normal functioning of an individual. Actually, the central nervous system controls most of the functions in a person's body and mind since it's made of the brain and the spinal cord ("What is the Central Nervous System?" par, 1).
The human brain, which is one of the parts of the central nervous system, is center of thoughts and determines how an individual interprets the external environment as well as controlling body movement. Similar to the central processing unit of the computer, the brain interprets information from the external environment through ears, eyes, skin, tongue,...
Lead and the Central Nervous System Lead is a highly toxic substance that particularly affects the central nervous system of all people of all ages. Because of its great toxicity, much research attention has been given to these effects and how they can be mitigated. Of particular importance are the effects of lead exposure in young children. Because their central nervous system is in a rapidly developing stage, children are at
Parkinson's Disease The human central nervous system is a miraculously designed functional piece of our bodies that helps us conduct the most essential tasks to help in our survival. It is therefore very important to investigate and understand how this system functions and operates. In this investigation it is also useful to understand how disease and malfunction of this system are affected. The purpose of this essay is to describe the
The circulatory or cardiovascular system is responsible for moving nutrients, wastes and gases between body cells, transporting blood across the whole body and battling disease (Circulatory System). Its principal elements are the heart, numerous blood vessels, and blood. The heart forms the circulatory system's core. This 2-sided, 4-chambered pump which distributes blood to various arteries comprises of the right and left ventricles, and right and left atria. The ventricles, situated within
Methylxanthines Yet another type of medication used to improve respiratory function is Methylxanthines. Some examples of these include Theophylline. These types of agents work similarly to bronchodilators which open the airway passage, in part by relaxing the bronchial or smooth muscles in the air passage ways. They also help promote greater circulation and engage the central nervous system so it can more actively work to provide oxygen throughout the body. Because
Vestibular and Olfactory Sensory Systems Static and Dynamic Equilibrium Mechanisms of Vestibular-Mediated Equilibrium There are two types of equilibrium that the vestibular system helps to maintain: static and dynamic (Virtual Medical Centre, 2010, para. 31). Static equilibrium provides feedback concerning head position or head movement when the body is stationary. In contrast, dynamic equilibrium involves sensing motion or acceleration/deceleration of the head. Acceleration can be further divided into sensing a change in linear
Anatomy and Physiology of the Skeletal and Muscular SystemsIntroductionToday, human health is being threatened on multiple fronts and it is not surprising that there is growing interest in developing a better understanding about the human body�s various systems and the respective roles they play in maintaining good health. Some people may intuitively recognize the importance of the skeletal and muscular systems to human health, but far too few understand the
