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

Homeostasis in the Human Body Homeostasis is the maintenance of a stable internal environment within tolerance limits‚ this is the restricted range of conditions where cellular operations effectively work at a consistent rate and maintain life. These conditions include temperature‚ blood glucose levels‚ pupil diameter control and many more. The body is made up of many cells. Many specialized cells group up to form a tissue. Tissues group up to form organs‚ these organs can then connect to form

Pigs live on a farm. Sadly‚ humans eat pigs for ham‚ pork and bacon. Bacon is good for the heart. Hearts are inside the human body. Without a heart‚ a human could not live. Without humans‚ our world would be over come with animals. Animals are important for the human world. Animals prove food‚ so humans can grow and become strong. Humans can exercise to strengthen their muscles. Muscles are very important for the human body. They are also very complex item in the body but are very important. Another

Function of the Skin The skin is more than just external covering. It acts as a sensitive boundary between our bodies and the environment. The skin has several important functions‚ for example: Protection‚ temperature regulations‚ waste removal and sense of touch. Protection • The skin acts as a protective organ. The film of sebum and sweat on the surface of the skin (acid mantle). It acts as an anti-bacterial agent to help prevent the multiplication of micro-organisms on the skin. • The fat

INTRODUCTION Leadership is less about your needs‚ and more about the needs of the people and the organization you are leading. Leadership styles are not something to be tried on like so many suits‚ to see which fits. Rather‚ they should be adapted to the particular demands of the situation‚ the particular requirements of the people involved and the particular challenges facing the organization. Our group chose Case 1 Restructure at Bunga Raya Bank for analysis. Briefly‚ Case 1 is about the different

I will also be outlining the structure of the main tissues in the body and the gross structure of all the body systems. 2 The components and functions of cells. Cell membrane All organisms have something in common‚ they all have a cell membrane. The cell membrane is a barrier that separates a cell

Respiratory system is quite obvious given that as human beings we need this system to help us with our most fatal tasks of breathing. Although the importance is assumed and acknowledged‚ many do not really get the whole concept of the Respiratory system. For example‚ how it works? Why it works? And what all is involved. These questions and others will be strategically answered in the following work. The Respiratory System delivers oxygen to the body and takes the carbon dioxide away. This system

of tissues in the human body that I am going to give examples of. These include the epithelial tissue‚ connective tissue‚ collagenous tissue and the nerve tissue. The first time of tissue is the epithelium tissue which has the function of helping to protect the body. There are four main types of epithelium tissues; squamous epithelial cells‚ Cuboidal epithelial cells‚ columnar epithelial cells and ciliated columnar cells. The squamous epithelium protects the linings in the body such as blood vessels

vital things in our lives and the chemistry they are made of. You are what you eat. But do you recall munching some molybdenum or snacking on selenium? Some 60 chemical elements are found in the body‚ but what all of them are doing there is still unknown. Roughly 96 percent of the mass of the human body is made up of just four elements: oxygen‚ carbon‚ hydrogen and nitrogen‚ with a lot of that in the form of water. The remaining 4 percent is a sparse sampling of the periodic table of elements.
