stimuli which activates pain receptors on neurons called nociceptors. Nociceptors can be placed into two categories: A-delta (Aδ) fibres and C-fibres. A-delta fibres are small‚ myelinated‚ neurons that transmit signals fast and mediate sharp pain. C-fibres are smaller unmyelinated neurons that slowly transmit signals. They mediate dull‚ aching pain. Both types of fibres stimulate secondary neurons that establish the ascending pathway which projects to the Thalamus in the brain. Sensations of pain

and I will outline them and their function in the body. One basic food is bread‚ other cereals and potatoes and the main nutrient for this type of food is carbohydrate‚ calcium‚ iron‚ B vitamins and dietary fibre. The main function of carbohydrate in the body is to provide energy. Dietary fibre is not absorbed but passes through the gastrointestinal tract‚ helping to keep it healthy before being excreted. The role of calcium is to develop and maintain the teeth and bones. Iron on the other is required

INTRODUCTION Australia is the world ’s largest wool producing country‚ and has been for decades. The fine quality of wool from the result of fine breeding has definitely help contribute to the high demand of the wool industry. Much of Australia ’s wool has been exported to other countries such as China‚ Italy‚ Taiwan‚ Republic of Korea and France. However‚ Australia ’s wool production has been decreasing for the last 10 years and the demand has been declining because of the other‚ easier to manage

This essay consists of four factors that contribute to premature skin ageing‚ it will first discuss how the skin ages and what happens to each layer of the skin and will then go on to explore the external and internal factors. Throughout‚ it will continue to explain the negative effects that each factor has on the skin and what can be done to prevent it. The skin is made up of three main layers. The outermost layer is called the epidermis‚ also known as the barrier layer‚ it is around 0.1mm thick

The lungs are made up of many types of tissue; the cartilages‚ ciliated epithelium‚ smooth muscle‚ squamous epithelium‚ elastic fibres and goblet cells and glandular tissue. The cartilage is a very stiff and flexible tissue‚ which doesn’t contain air vessels. It is found in trachea‚ bronchus‚ bronchiole and alveolus‚ and it has a structural role. It support‚ and gives strength to trachea and bronchi. It holds the airways open for the resistance with little airway. This prevents it from collapse

network is usually clustered in close proximity to other computing resources but may also extend to remote locations for backup and archival storage. A storage area network can use existing communication technology optical fiber or it may use the newer Fibre Channel technology. Some SAN system integrators liken it to the common storage bus (flow of data) in a personal computer that is shared by different kinds of storage devices such as a hard disk or a CD-ROM player.
