Generally, disruptions at a cellular level usually involve changes or damage to the cells themselves, or they involve the presence of unexpected material within the cell, such as [[Pigmentation - Pathology|pigments]] or [[Mineralisation_-_Pathology#Calcification|calcified material]]. When cells begin to [[Degenerations and Infiltrations - Pathology|degenerate]] or become [[Degenerations and Infiltrations - Pathology|infiltrated]] by foreign material then cellular metabolism has been disrupted. The alteration in the structure of the cell can be suggestive of the metabolic abnormality that has occurred, and result in the cellular parameters extending beyond the normal physiological range for the cell.

There are several [[Disorders of Cell Growth - Pathology|changes in the size of cells]] and their respective organs that are commonly seen in pathological states:
There are several [[Cell Growth Disorders|changes in the size of cells]] and their respective organs that are commonly seen in pathological states:
*'''Atrophy''' is a decrease in the size of the cells and respective organ(s), occurring after the organ has reached it's normal size.
*'''Atrophy''' is a decrease in the size of the cells and respective organ(s), occurring after the organ has reached it's normal size.
*'''Hypertrophy''' is an increase in the size of an organ due to an increase in size of the individual cells.
*'''Hypertrophy''' is an increase in the size of an organ due to an increase in size of the individual cells.
