How The Human Body Can Work Out All These Processes And Interactions With The World Around Us

The human sensors have proved to be something quiet spectacular, in how our body can work out all these processes and interactions with the world around us, however what if I was to tell you that our body can identify chemical makeup of almost any object in the real world. This is possible with our sense of taste and smell, using the human nose and tongue which in many areas assist each other to create this. Smelling, it’s the human body’s power of perceiving odours or scents by means of the organs in the nose it’s an amazing ability. Our sensation of taste is the just as amazing, as it perceives the flavours received in the mouth and throat on contact with a substance. Within in this presentation I hope to give you all the knowledge as to …show more content…

These brain centres perceive odours and access memories to remind us about people, places, or events associated with these olfactory sensations. Our sense of taste works when the chemical substances responsible for the taste is freed in the mouth and comes into contact with a nerve cell. It activates the cell by changing specific proteins in the wall of the sensory cell. This change causes the sensory cell to transmit messenger substances, which in turn activate further nerve cells. These nerve cells then pass information for a particular perception of flavour on to the brain. The numerous wart-like bumps on the mucous membrane of the tongue are where the substance producing the taste is transformed into a nerve signal. These bumps, which are called taste papillae, contain many sensory cells with a special structure: together with other cells they make up a bud that looks a bit like an orange with its sections arranged around a centre. In the middle of the top side is a small indentation filled with fluid. The chemical substances responsible for the taste are washed into this funnel-like hollow. This makes sure that the substances are detected and analysed by as many sensory cells as possible before being swallowed. The nose and tongue in the human body both work together to create taste and use conflicting chemicals to help the brain to identify the flavour or taste
