Why anatomy? Anatomy is a branch of biology that concerns the study of the structure of organisms and their parts. It explains how the body and many of its systems work. Having this kind of knowledge can benefit in many ways. It is necessary to know how the body works to maintain homeostasis. You only have one body and need to keep it healthy to live. An understanding of medical care and anatomy may be able to save the lives of family, friends, and possible bystanders. If you develop a liking for healthcare, it is very much possible to pursue a career. Many consider it the best science because it is a stable bank of knowledge and a mechanism of injury.
To fully understand the mechanism of injury, we must first know the different parts of the body. The three main body cavities are the cranial, thoracic, and abdominopelvic cavities. The cranial cavity consists of the brain and cerebral spinal fluid (CSP), which cushions the brain from injury and transmits neuromodulators through the spinal cord. The thoracic cavity consists of the heart, lungs, esophagus, trachea, and thymus. Some of these organs are organized into the mediastinum, the central part of the thoracic cavity. The abdominopelvic cavity consists of four quadrants: right upper, right lower, left upper, left lower. In them lies the stomach, small and large intestines, bladder, appendix, kidney, spleen, gallbladder, liver, pancreas, and reproductive system. Knowing the different organs, cavities, and where they are help us to understand how urgent an injury is. A neglected dental infection in the dental cavity may make its way into the sinus cavity. From there it can spread into the cranial cavity, which may cause it to be fatal.
Dr. Stacey Upshaw came to speak to us about all of this asking the question "why anatomy?" The real question is why not? Why not study the subject that defines us and describes us as humans? Anatomy is us. Without it, we wouldn't have made it this far as a society and species.
