Cat Dissection And Cat Similarities

To conclude our study of physiology and anatomy, we will be dissecting a cat. A dissection is a process of cutting apart or separating tissue as, for example, in comparative anatomy studies or in the course of a surgical procedures. It is also for educational purposes and also to learn how different parts of the body are connected and work together. Comparative anatomy is the study of the similarities and differences in the structures of different species. Comparing its structural similarities may use to determine their evolutionary relationships. Organisms with similar anatomical features are assumed to be relatively and closely related evolutionarily, because of this they are assumed to share a common ancestor. As a result of the study of

Also the cat is chosen for this because of its anatomy that’s similar to that of humans, and its size makes it easy to observe and dissect. The study of animals in science education has been around since the 1960s and it continues to be an important part of a classroom today. Cat dissection isn’t only used for an anatomy class though it’s also used for psychology, behavior, and other subjects. People considered using a cat for dissection because it can relate to many different animals and even humans. A cat can even relate to other mammals such as whale and bat. With all of this being said, our purpose for this laboratory dissection is again to identify the anatomical structures of a cat and compare it to human bodies to find similarities and differences therefore it provides relevant information to how human anatomy works. Because all of the organs are virtually the same and have the same function, felines are definitely good models for understanding the human anatomy. There are differences though, that make one unique compared to the other. Similar body parts are under homologies or analogies however, both provide evidences for a certain species evolution. Homologous structures are structures that are similar in related organisms because they’re inherited from a common ancestor. These structures may or may not have the same functions from their descendants example of this is their forelimbs. They inherited this pattern from a common ancestor. However, their forelimbs now have different functions. On the other hand, analogous structures are structures that are similar in unrelated organisms. The structures are similar because they evolved to do the same job, not because they were inherited from a common ancestor. They also have the same function. However, wings evolved independently in the two groups of animals. This is
