Responses to Cell Injury

This course provides an overview of cellular adaptations to chronic stress, including atrophy, hypertrophy, hyperplasia, metaplasia, and dysplasia. It also covers mechanisms of cell death (necrosis and apoptosis) and the major patterns of necrosis using gross and microscopic features, forming a foundational framework for understanding pathological processes.

About Course

The Responses to Cell Injury course introduces learners to the fundamental cellular changes that occur in response to stress and damage. The course explores key adaptive processes such as atrophy, hypertrophy, hyperplasia, metaplasia, and dysplasia, which enable cells to respond to chronic stress conditions.

Students will also examine the mechanisms of cell death, including necrosis and apoptosis, along with the major patterns of necrosis identified through gross and microscopic features. Emphasis is placed on understanding these processes as the foundation for studying disease development and pathological changes in tissues and organs.

What You'll Learn

By the end of this course, you will be able to:

  • Define and provide examples of the five main cellular adaptations to chronic stress: atrophy, hypertrophy, hyperplasia,  metaplasia, and dysplasia.
  • Differentiate between physiological (normal) and pathologic (disease-related) adaptations
  • Necrosis, covering their mechanisms, morphology, and fate in the body.
  • Apoptosis covering their mechanisms, morphology, and fate in the body.

Prerequisites

To be successful in this course, you should have a basic background in human anatomy and physiology, introductory histology, and fundamental concepts of cell biology, including membrane structure and basic metabolic processes.

Who Can Take This Course?

This course is for undergraduate students in medicine and allied health sciences (including physiotherapy, nursing, and biomedical sciences) who require foundational knowledge of cellular injury, adaptation, and death to support their understanding of pathology and clinical disease processes, aligned with core concepts outlined in Robbins and Cotran Pathologic Basis of Disease.
