Study Notes
Adaptation and Compensation
- Adaptation is a pathological concept encompassing all vital processes that help organisms interact with and survive in their environments.
- Compensation is a type of adaptation targeted at diseases that addresses the restoration or correction of damaged functions and structures.
- Compensation can occur at various levels, from molecules to systems, helping the organism maintain function.
- There are several compensatory/adaptive processes:
Regeneration
- Regeneration is the restoration of tissues or organs to their original structure and function after injury or damage.
- Types of regeneration:
- Physiological regeneration: occurs in normal physiological conditions, like normal tissue repair.
- Reparative regeneration: restores tissues damaged by disease or injury.
- Pathological regeneration: occurs after injury or disease. It involves the processes of cell growth, division, and differentiation to replace the damaged tissue or to restore its original structure.
Hyperplasia
- Hyperplasia is an increase in the number of cells in a tissue or organ.
- It can be a response to physiological stimulation, such as pregnancy or increased hormone production.
- It can also be a response to pathological conditions.
Hypertrophy
- Hypertrophy is an increase in the size of cells in a tissue or organ.
- It often occurs when the cells are subjected to increased stress or demand, such as increased workload.
Atrophy
- Atrophy refers to a decrease in the size or function of a cell, tissue, or organ.
- Types of atrophy include physiological atrophy (occurs naturally) and pathological atrophy (caused by disease or injury).
Metaplasia
- Metaplasia is a change in the type of cells in a tissue or organ.
- This can occur as a result of chronic irritation or injury.
Healing by First Intention
- Healing by first intention, or primary union, involves the direct approximation of wound edges.
- This process is characterized by minimal scarring and rapid healing.
Healing by Second Intention
- Healing by second intention involves the healing of wounds with a significant degree of tissue loss.
- It often results in more extensive scarring compared to healing by first intention.
