The Importance of Anatomy and Physiology Courses
Anatomy is the scientific branch of physiology concerned with the arrangement of the various parts of an organism. Anatomy is an ancient science, having its origins in prehistoric times. Modern anatomists are aware of the fact that all of our organs and systems are made up of complex networks of nerves, blood vessels, muscles, and bones. There are literally thousands of hormones and nutrients that are involved in the nervous system, and nearly all of these play vital roles in organ function. However, understanding how all these components work together to produce organs and tissues that function properly is largely a matter of understanding the basic anatomy of living things.
Anatomy is literally the language of life. Every living thing is made up of a complex network of cells and tissue, and the understanding of how all of this interlinks is an important part of modern medicine. Physicians who perform surgery rely on the accuracy and precision of radiography to determine the location of internal problems and injuries, and medical books and articles on the subject abound on the internet. Despite the importance and usefulness of anatomy in medicine, many students lack a fundamental understanding of it, so they fail to pass the required medical entrance examination. The lack of basic knowledge of anatomy can have serious consequences in higher education, because students need to understand anatomy in order to perform well in their courses and fulfill their prerequisites.
When a student takes anatomy studies, he/she will learn many fundamental concepts of physiology and medical terminology. However, anatomy is much more than a simple course of study; understanding anatomy is essential to learning about physiology and the other components of the human body. For example, although the heart is part of the body, physiology will not cover the heart function and circulation, because the heart is one of many components of the body. Understanding how the different parts interrelate with each other, and how they produce the physiological processes that compose the human body, is necessary for nurses, doctors, and other medical professionals.
Anatomy has many different levels of organization, depending on the type of tissue that is being studied. In addition to the major organs, there are the major structures, or anatomic structures. These include the heart, lungs, stomach, intestines, reproductive organs, and so on. The structure of these structures gives rise to differences in function, physiology, and medical terminology. Thus, anatomy presents both the basic level of understanding and terminology, and different levels of study as well. One example of this is between cardiovascular and coronary anatomy.
The first step to understanding anatomy is through the dissection of living organisms. In case of humans, this would be the torso, brain, and so on. An animal or insect dissection can be just as enlightening. There are many different types of animals that can be dissected: rats, dogs, cats, and so on.
Microscopy is part of the process of studying anatomy and characterized by fine sections of skin or other matter with a microscope. This allows an expert to look closely at tissues, organs, and cells for characteristics such as size, shape, and density. One of the fields of microdissection best illustrated through practice is histology. Histology uses tissues from human or animals to study tissue diseases such as allergies or cancer. For example, a pathologist may examine lung cancer using microscopic anatomy and tissue biopsy.
Anatomy education helps people make healthy and informed choices regarding health, especially concerning disease. With knowledge of anatomy, patients can better diagnose certain illnesses and treat them before progress is made. For example, the early detection of breast cancer is essential for breast cancer survivors, as well as patients who are diagnosed with a heart ailment. A thorough understanding of anatomy helps people choose the best course of action and not be taken by surprise by any illness or disease
Anatomy and physiology courses offer many career options, depending on which fields of expertise one is most interested in. For example, while those interested in the human anatomy are able to seek employment as cardiologists, ophthalmologists, or physicians, those interested in physiology can pursue positions in clinical or research laboratories, as well as in other types of healthcare settings. Those who are enrolled in an undergraduate program in anatomy and physiology can expect to take up to two years to complete their degree and obtain their doctorate degree.
