Study Notes

Cellular Development Terms

  • -plasia: Indicates changes in the number and morphology of cells.
  • a/plasia: Denotes either a total lack of cell growth or a significant reduction in cell development.
  • ana/plasia: Refers to an abnormal growth of undifferentiated cells, often associated with malignant conditions.
  • dys/plasia: Involves the production of cells or tissues that are abnormally formed, which may indicate precancerous changes.
  • hyper/plasia: Characterized by an abnormal increase in the number of cells, commonly seen in glandular tissues.
  • hypo/plasia: Indicates a decrease in the number of cells or tissues, potentially resulting in organ dysfunction.

Size Changes in Tissues and Organs

  • -trophy: Pertains to variations in the size of cells and their respective organs.
  • a/trophy: Represents a reduction in the size of tissues, often leading to wasting conditions.
  • hyper/trophy: Describes an enlargement of cells, tissues, or organs, which can occur due to increased demand or hormonal stimulation.
  • hypo/trophy: Associated with progressive degeneration of tissues, synonymous with atrophy.

Growth Origin Terminology

  • -genesis: Relates to the original development and formation of cells and organs.
  • a/genesis: Refers to the complete absence of original developmental processes, resulting in missing structures.
  • hyper/genesis: Involves the repeated creation of body parts or organs, such as the formation of supernumerary organs.
  • hypo/genesis: Indicates congenital underdevelopment of organs, often leading to functional deficiencies.
