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

The world contains all kinds of energy that translates into information about what we see‚ hear‚ smell‚ touch and taste. A sensory system is a part of the nervous system responsible for processing specific sensory information. The components of a sensory system include sensory receptors‚ neural pathways‚ and parts of the brain involved in sensory perception. To begin‚ energy from the environment stimulates the receptor cells in whichever sense organ is being used. If this information were auditory

1-Drainage system- A drainage system is the pattern formed by the streams‚ rivers‚ and lakes in a particular drainage basin. They are governed by the topography of the land‚ whether a particular region is dominated by hard or soft rocks‚ and the gradient of the land. 2-Drainage basin-A drainage basin is an extent or an area of land where surface water from rain and melting snow or ice converges to a single point‚ usually the exit of the basin‚ where the waters join another waterbody‚ such as a

In any nervous system‚ there are 4 main components: (1) sensors: gather information from the external environment (sense organs) (2) conductors: carry information from sensors to modulators or from modulators to effectors (nerves)

human body? Do you know how it functions on a daily basis? Our body is made up of different organs and systems that work together every day and night. If these systems and organs didn’t exist we would not be able to function in this world. There is one particular system that is extraordinary‚ and it is devised to channel blood in or bodies. It has many organs put together that helps your body maintain your internal environment and fight diseases. This system is called the cardiovascular system. The

The Respiratory System The human respiratory system plays a very important part in our bodies. Without it‚ we wouldn’t be alive! We need air to move through our bodies at all times. Breathing‚ is a key necessity for life. Our respiratory system is made up of many organs that all work together. The goal of breathing is to deliver oxygen to the body and take away carbon dioxide. The respiratory system organs all work together‚ like a engine in a car‚ they all have a important role. Some

Energy Systems Our body needs a supply of energy to complete day to day tasks and to simply be able to move. We have more than one energy system‚ we have 3 in total and these are * ATP (anaerobic) * Lactic acid (anaerobic) * Aerobic (aerobic) All three off these energy systems are fuelled by the same chemical called ADP-PC. These systems produce this chemical at different speeds‚ for example the ATP system produces the chemical very fast as for the aerobic energy system produces it

Energy systems Creatine Phosphate system The creatine phosphate system is an immediate energy system. ATP (adenosine triphosphate) is created without the presence of oxygen for short‚ fast bursts of power and energy. This is the first system used when performing any sporting activity. However this short burst of energy only lasts for a short moment in time for round about 10 seconds. Running events like the 100 meters sprint would be an example of using the creatine phosphate system. During the

Skeletal System Caleb Cornelious The skeletal system is one of the most important systems in the human anatomy. Without this system our bodies wouldn’t have any source of motion or movement. From the skull all the way to the toes of our feet‚ everything is important. Out of the 206 bones‚ they all form our different shapes and make us all unique. They create our frame work and enables us the move and perform our different activities during our everyday life. Another thing that the skeletal system does

The Indian education system has taken a step forward towards reviving the education system with the introduction of grading system in session 2009-10. It will help in reducing the pressure on students during exams. In the last five years the meaning of education has changed for students from imbibing knowledge to merely scoring marks‚ resulting in myriad forms of education policies. As per reports‚ every day more than 17 students aged between 15-25 years commit suicide in India due to non-performance
