Anatomy is the identification and description of the structures of living things. It is a branch of biology and medicine. People who study anatomy study the body, how it is made up, and how it works.
The study of anatomy dates back more than
- human anatomy
- animal anatomy — zootomy
- plant anatomy — phytotomy
Human anatomy is the study of the structures of the human body. An understanding of anatomy is key to the practice of medicine and other areas of health.
The word “anatomy” comes from the Greek words “ana,” meaning “up,” and “tome,” meaning “a cutting.” Traditionally, studies of anatomy have involved cutting up, or dissecting, organisms.
Now, however, imaging technology can show us much about how the inside of a body works, reducing the need for dissection.
Below, learn about the two main approaches: microscopic anatomy and gross, or macroscopic, anatomy.
In medicine, gross, macro, or topographical anatomy refers to the study of the biological structures that the eye can see. In other words, a person does not need a microscope to see these features.
The study of gross anatomy may involve dissection or noninvasive methods. The aim is to collect data about the larger structures of organs and organ systems.
In dissection, a scientist cuts open an organism — a plant or the body of a human or another animal — and examines what they discover inside.
Endoscopy is a tool for diagnosing illness, but it can also play a role in research . It involves a scientist or doctor inserting a long, thin tube with a camera at the end into different parts of the body. By passing it through the mouth or rectum, for example, they can examine the inside of the gastrointestinal tract.
There are also less invasive methods of investigation. For example, to study the blood vessels of living animals or humans, a scientist or doctor may inject an opaque dye, then use imaging technology, such as angiography, to see the vessels that contain the dye. This reveals how the circulatory system is working and whether there are any blockages.
MRI scans, CT scans, PET scans, X-rays, ultrasounds, and other types of imaging can also show what is happening inside a living body.
Medical and dental students also perform dissection as part of their practical work during their studies. They may dissect human corpses.

Most people working in healthcare have had training in gross anatomy and histology.
Paramedics, nurses, physical therapists, occupational therapists, medical doctors, prosthetists, and biological scientists all need a knowledge of anatomy.
