Human Anatomy, Animal Anatomy, and Plant Anatomy are the various branches of Anatomy. Among these three, human anatomy was the one that was most thoroughly studied and used to examine the internal organs, wounds, and other wounds of a person.
Human anatomy has different branches which are as follows :
Macroscopic or Gross Anatomy
Macroscopic or Gross Anatomy primarily focuses on the study of large body parts that are visible to the unaided eye. For example, the anatomy of the kidney, the digestive system, the lungs, etc.
Surface anatomy, systemic anatomy, and regional anatomy are other divisions of gross anatomy. They are been explained below:
- Regional Anatomy: Regional anatomy is referred to as an examination of several structures within a specific area.
- Systemic Anatomy: Systemic anatomy is referred to as an examination of human structures, system by system.
- Surface Anatomy: Surface anatomy refers to the study and examination of a person's body's interior structures solely.

Microscopic Anatomy
This anatomy focuses primarily on the study of incredibly tiny and minute structures those that can only be seen under a microscope.
- For example, it deals with several cell types.
- Cytology and histology are two further subfields in the study of microscopic anatomy.
- Human blood cells are the subject of cytology, while different bodily tissues are the subject of histology.
Developmental Anatomy

This anatomy is a field of study that focuses on the many structural changes that the body goes through as people age. The goal of embryology anatomy is to comprehend the event process before birth fully.
- To understand devlopnment anatomy, one must know about musculoskeletal function and how both structure and performance are affected by exercise or illness.
- On the other hand, exercise physiologists face a significant problem in anatomical teaching where understanding anatomy is becoming more and more crucial.
- There is a severe lack of exercise physiologists willing to demonstrate macroscopic anatomy for instructional purposes.
What is Physiology?
[Click Here for Sample Questions]
Physiology is the study of a body's overall functional system is known as physiology. It is included in the field of science and biology. It is divided into three parts:
- System Physiology: Essentially, it studies how all the body's systems function.
- Comparative Physiology: Essentially, it is the study of many traits of living things.
- Medical Physiology: It is the study of Genetic Disorders related to the operation of the physical systems of the body as well as physiological dysfunctions.

Sample Questions
Ques. What is meant by Anatomy? (2 Marks)
Ans. Anatomy can be defined as the study of scientific and biological branches that primarily focus on human, animal, and plant anatomy. Among these three, the human anatomy was the one that was most thoroughly researched because it was also used to examine the internal organs, wounds, and other wounds of a person.
Ques. What is meant by Physiology? What are its major types? (3 Marks)
Ans. The study of a body's overall functional system is included in the field of biology and science known as physiology. It is additionally divided into
- System Physiology: It is the study of how all of the bodily systems work together as a whole.
- Comparative Physiology: This field of study examines numerous traits of living things.
- Medical Physiology: It is the study of diseases and physiological dysfunctions related to how the physical body systems work.
Ques. What is meant by Gross Anatomy? What are its branches? (3 Marks)
Ans. The study of large bodily components that are readily visible to humans with the unaided eye is known as gross anatomy. For instance, the anatomy of the kidney, the digestive system, the lungs, and other organs that are visible to the unaided eye and hence amenable to study are examples of gross anatomy. Surface anatomy, systemic anatomy, and topographic anatomy are other divisions of gross anatomy.
- Regional Anatomy: The study of the different structures within a particular region is known as regional anatomy.
- Systematic Anatomy: Systematic anatomy is the study of the human body's structures system by system.
- Surface Anatomy: Surface anatomy refers to the study of a person's body's interior structures alone.
Ques. Who founded Anatomical Science? (2 Marks)
Ans. Herophilus is referred to as the Father of Anatomy, just as Hippocrates is known as the Father of Medicine. He was arguably the finest anatomist of antiquity and possibly all time, according to the majority of people. Vesalius, who lived and worked in the 16th century A.D., is the only one who might disagree with him in this opinion.
Ques. What is the importance of Physiology? (3 Marks)
Ans. Physiology is important for because:
- Research in physiology helps in our understanding of how the body functions in health and how it responds to and adapts to the stresses of daily life.
- It also aids in our understanding of what goes wrong with the diseases.
- It makes it easier to develop new treatments and recommendations for maintaining the health of humans and animals.
Ques. Who named Organs? (2 Marks)
Ans. Body parts such as bones, organs, and muscles were given names based on how they appeared by Greek scientists, who were followed by Roman and mediaeval scientists.
Ques. What are the area of functioning in Physiology? (2 Marks)
Ans. The study of physiology deals with areas like growth and reproduction, health benefits, exercising, intestinal microbiomes, lung function and breathing, sleep research, extreme conditions, surviving in space, and life conservation.
Ques. Who are the founders of medicine, anatomy and physiology? (2 Marks)
Ans. Because of his more than 70 publications, Hippocrates is regarded as the founder of modern medicine. Following the extensive observation, he scientifically defined numerous ailments and associated treatments. Andreas Vesalius is the founder of anatomy. Carl Ludwig is the founder of modern physiology.
Ques. What is Importance of Anatomy? (3 Marks)
Ans. The importance of anatomy is as follows:
- Knowledge of anatomical structure of the body is important to understand musculoskeletal function and how the structure and function are modified.
- It is necessary for professionals in physical therapy and athletic training and as well as for exercise physiologists too.
Ques. What are the differences between anatomy and physiology? (5 Marks)
Ans. The differences between anatomy and physiology are as follows:
| Particulars | Anatomy | Physiology |
|---|---|---|
| Definition | The area of research that examines how humans, animals, and other living things are put together, particularly as revealed via dissection and the division of organs. | The area of biology examines how living things normally behave and what makes them up. |
| Founders | Andreas Vesalius | Carl Ludwig |
| Importance | Anatomy is important in the study of medicine and other life sciences because it teaches us about the various parts of living things, such as plants, animals, and people, as well as their structures and distinguishing characteristics. | Research in physiology aids in our understanding of how the body functions in health and how it responds to and adapts to the stresses of daily life. It also aids in our understanding of what goes wrong with the disease, making it easier to develop new treatments and recommendations for maintaining the health of humans and animals. |
