It essentially includes the understanding and interpretation of structure both external and internal. Anatomy It is the study of gross internal structure of organs and different parts. It ascertains the identification and similarities of one organism with other organism in the course of studies.
Some organism have considerable similarities in external and internal features, where as in some organisms, there is close resemblance in external features but they differ in internal structure.
For example — Man, Monkey and Dog have analogy in internal organ system but externally all of them differ from one another. Histology The body of various plants and animals are composed of different kinds of organs and organ systems. These organs are formed by special structures called tissues. The tissues are the groups of such cells which are similar in structure, function and origin. Thus the tissues are microscopic structures and can be studied only with the help of microscope.
Substantially the microscopic study of internal structure of living organism is called as Histology. Cell Biology The body of living beings is composed of one or many cells.
The structure, function and division of the cell directly determines the life activities of living beings. All researches or studies related to cell are included under the branch known as Cell Biology. It involves the studies of all kinds of cells and their behaviour.
