A case study of a professional cyclist with a fractured clavicle. The aim of the following case study is to describe the structure and function of the musculoskeletal system using a 20 year old professional cyclist who sustained a fractured clavicle during a race. The author will discuss the effects of the injury on the normal functions of the systems of the body‚ and the impact on his physical‚ psychological and social well-being. The author will also summarise the pathological changes that occurred

Transitions of Reptiles to Mammals A long long time ago‚ in a galaxy not too far away‚ was a little blue planet called Earth‚ and on this world not a single mammal lived. However a lot of time has past since then and we now have lots of furry creatures that are collectively called mammals. How did they get their? Where did they come from? These are the kinds of questions that led me to my subject of choice. I will endeavor to provide examples‚ using specific transitional fossils‚ to show that

To accomplish this we will be dissecting and identifying parts in a number of different systems: external features‚ the skeleton‚ the muscles‚ internal organs‚ the respiratory system‚ the digestive system‚ the circulatory system‚ the urinary system‚ the reproductive system‚ and the nervous system.
