Human Anatomy Introduction

Human Anatomy is the foundation of medical studies in which we study structure of a human body. Anatomy is the branch of biology which deals with the structure of living organisms and their parts.

There are three main branches of anatomy:

  1. Macroscopic Anatomy
  2. Microscopic Anatomy
  3. Developmental Anatomy

Macroscopic Anatomy

Also known as Gross Anatomy, it is the study of structures of living organism which is visible to unaided eye without the use of microscope. As the gross anatomy is studied on dead bodies it is also named as cadaveric anatomy

It is approached in two ways

  1. Systemic Approach: In systemic approach, living body is studied by considering each system separately. Like, Digestive system, integumentary system etc.
  2. Regional Approach: In regional approach, living body is studied by dividing it into different regions like,
    • Upper limb
    • Lower limb
    • Thorax
    • Abdomen
    • Head and neck

Microscopic Anatomy

Also known as histology, it is the study of structures of living organisms which is not visible to unaided eye but requires the use of microscope. It studies structure of human body at tissue level.

Developmental Anatomy

Also known as embryology, is the study of how zygote is formed and changes through which fetus goes before it is born.
