Trapezius muscle pain or trapezius myalgia is common in women who perform repetitive tasks. It is also common in women who sit in one position with little motion of the arms such as working at a computer keyboard or sitting at a desk.
The Swedish botanist Carolus Linnaeus is regarded as the father of taxonomy, as he developed a system known as Linnaean classification for categorization of organisms and binomial nomenclature for naming organisms.ristotle used a very simple system of classification. He divided all living thing into two groups: plant and animals. Some of the terms he gave to animals, such as  invertebrates  and  vertebrates  are still commonly used today.
Linneaeus developed a hierarchy of groups for taxonomy. To distinguish different levels of similarity, each classifying group, called taxon (pl. taxa) is subdivided into other groups. To remember the order, it is helpful to use a mnemonic device.
