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 2,000 years, to the Ancient Greeks. There are three broad areas:
•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.
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.
Microscopic anatomy, also known as histology, is the study of cells and tissues of animals, humans, and plants. These subjects are too small to see without a microscope.
Through microscopic anatomy, people can learn about the structure of cells and how they relate to each other.
For example, if a person has cancer, examining the tissue under the microscope will reveal how the cancerous cells are acting and how they affect healthy tissue.
A researcher may apply histological techniques such as sectioning and staining to tissues and cells. They may then examine them under an electron or light microscope.
Sectioning involves cutting tissue into very thin slices for close examination.
The aim of staining tissues and cells is to add or enhance color. This makes it easier to identify the specific tissues under investigation.
People who work in histology laboratories are called histotechnicans, histotechnologists, or histology technicians. These people prepare the samples for analysis. Histopathologists, also known as pathologists, study and analyze the samples.
The technician will use special skills to process samples of biological tissues. The tissues may come from:
•patients seeking a diagnosis
•suspects in a crime, if it is a forensic lab
•the body of a person who has died
The process involves:
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.
