Facts about Anatomy

Anatomy is the study of body parts which can be seen easily through our naked eyes.

What is Anatomy?

Anatomy can be defined as a study of the internal structure and organs of living beings. In the field of medicine, life science and in other research sectors, anatomy plays a vital role by helping to learn about the structures, characteristic features and other different parts in all living organisms, including plants, animals, birds, insects and humans.

There are different types of Anatomy.

Types of Anatomy

Microscopic Anatomy

This is also called Histology, which mainly deals with the study of cells, tissues and other small or minute structures or living things which are not visible to the naked eye.

Gross Anatomy

This is also called the Macroscopic anatomy, which mainly deals with the study of different structures, which are visible to the naked eye. This type of anatomy provides complete structural information along with its internal and external parts.

Human Anatomy

The type of anatomy, which mainly deals with the study of different structures and their parts in the human body. This type of anatomy mainly focuses on different organ systems, including the circulatory system, digestive system, endocrine system, excretory system, muscular system, nervous system, respiratory system, reproductive system and skeletal system.

Plant Anatomy

This is also called phytotomy. It mainly deals with the study of the internal structure of plants including the cells, tissues, roots, stem, leaves, flower, fruit and seeds.
