Q1 Proprioception is the sense that gives us our awareness of the relative positions of the different parts of our bodies. The system has sensors within joints‚ muscles and skin which relays information to the brain about joint angles and skin and muscle stretch. Its role is to act as the start point of any sequence of movement as without information about where we are now we could not format the instructions for moving to where we want to move to. Rather like asking a GPS system to guide you

analogous to sensory cells of the antennae of invertebrates. In humans‚ olfaction occurs when odorant molecules bind to specific sites on the olfactory receptors. These receptors are used to detect the presence of smell. They come together at the glomerulus‚ a structure which transmits signals to the olfactory bulb (a brain structure directly above the nasal cavity and below the frontal lobe).[2] Many vertebrates‚ including most mammals and reptiles‚ have two distinct olfactory systems—the main olfactory

ANATOMY AND PHYSIOLOGY Chronic Kidney Disease Cardiovascular System The cardiovascular system is sometimes called the circulatory system. It consists of the heart‚ which is a muscular pumping device‚ and a closed system of vessels called arteries‚ veins‚ and capillaries. As the name implies‚ blood contained in the circulatory system is pumped by the heart around a closed circuit of vessels as it passes again and again through the various "circulations" of the body. The Heart * The heart

Diabetes Assignment This assignment will be looking at the pathophysiology of Type 1 diabetes‚ the effects this has upon Carol in terms of symptoms and how it may affect the developing embryo and foetus. What is Type 1 Diabetes? Diabetes type 1 is an organ specific autoimmune disease which develops in the pancreas and islet cell antibodies when the body’s immune system attacks and destroys insulin producing beta cells (Nelson-Piercy‚ 2005). This affects the metabolism of fats‚ proteins and
