Introduction To Biology

Biology is ‘’study of life". It is a vast subject that covers in details of chemical machines in our body. The Biologists research the human brain, the forming of genes and including the reproductive system. Biologists also study the DNA. Biology studies natural science, life and living organisms.

There are four major categories in Biology, Cell theory, Gross Anatomy, Microscopic Anatomy and Basic Anatomy.

Important aspects of Biology

• Cell Theory
• Gross Anatomy
• Microscopic Anatomy
• Basic Anatomy

Cell Theory

Cells are the life sustaining structure in every living thing on the face of the earth.  This theory became a big development in the middle of the 17^th century due to major inroads made by microscopy in medical world.  The cell theory is one of the foundations in biology. The cell theory reveals that new cells give birth to every existing cell, and that the new cells form the fundamental unit of structure, function and organization in all living organisms.

Gross Anatomy

The macroscopic details of human structure are called Gross Anatomy. It does not bother about microscopic structural details of human body but is studied with the naked eye. Gross Anatomy is studied in two ways. One is through systematic study and the other through regional approach. In systemic approach, the human body is considered to be composed of different organs systems and in regional approach, human body is considered to be composed of different regions.

Microscopic Anatomy

Microscopic anatomy deals with the study of microscopic details of various structures of human body. Microscopic anatomy depends on an important instrument known as the microscope.

Basic anatomy

Though Basic Anatomy is not considered as a major subdivision of human anatomy still it is considered to be an important learning opportunity for medical students who study medicine. Basic anatomy explains in detail all the basic nuances of human anatomy so that the different structural arrangements of these basic components can be understood properly.
