Anatomy is a branch of science concerned with the study of structure in animals, human beings and living organisms. Human anatomy is a segregated subject of study. Anatomy of any living organisms other than the human body is termed as ‘Zootomy’. Speaking of living organisms, plants are also classified as living objects.
However, instead of referring the anatomy of plants as Zootomy, it is known as Phytotomy. In general, the term ‘Anatomy’ is coined from two Greek words ‘Ana‘ and ‘Tome‘ meaning “up” and “a cutting“. Earlier, anatomy was virtually understood as dissection. However, researches and studies have remodeled the concept of anatomy over the decades, defining dissection a crucial part of anatomy and not the subject as a whole.
Types of Anatomy
Since anatomy is elucidated as the identification of physical structures in living things, it is broadly classified into two categories. Let us quickly take a look at these categories and understand the concept well.
- Gross Anatomy – Better known as Macroscopic anatomy, gross anatomy refers to the study of biological structures that are easily viewed with naked eyes. Sometimes gross anatomy is also called topographical anatomy. Parts of the body like heart, bones, eyes and lungs are very much visible to our naked eyes. The study of such structures defines the concept of gross anatomy. Speaking of study, the concept of dissection ropes in. In anatomy, cutting open a human cadaver to observe and record structural details is easy. However in gross anatomy, studies can be performed using non-invasive procedures. For example, in Endoscopy, a simply tube is inserted in the body fitted with a camera in the end. This is enough to observe the physical structure of the living organism inside. X-Ray, Angiography and MRI (Magnetic Resonance Imaging) are other examples of performing gross anatomy using non-invasive methods.
- Microscopic Anatomy – Right as the name suggests, microscopic anatomy deals with the study of cells and tissues of living organisms that are impossible to be viewed with naked eyes. Since learning about tissues and cells require procedures like sectioning or cutting up the tissue in small, delicate slices and staining to enhance the color of the tissues and cells for better distinguishing, microscopic anatomy is also called histology. The study of cells under microscopic observation is often termed as cytology.
