Which type of repair involves the generation of new cells of the same type that can perform the same function?

• A. Resolution
• B. Granulation tissue
• C. Regeneration
• D. Fibroblastic repair

Answer: (C)

The correct answer is regeneration because this process specifically focuses on the replacement of damaged or lost tissue with new cells of the same type that can perform the same functions as the original tissue. In regeneration, the cells proliferate and restore the tissue to its original structure and functionality, allowing for a complete recovery from injury.

In contrast, resolution refers to the process where an injury heals and the tissue returns to its normal state without any functional loss, but it does not involve the generation of new cells. Granulation tissue is an intermediate phase in the healing process where new connective tissue and blood vessels form. Although it is essential for healing, it does not imply the restoration of the same type of cells that originally existed. Fibroblastic repair is part of the healing process where fibroblasts proliferate and synthesize collagen and other extracellular matrix components; however, this can lead to scarring rather than the restoration of the initial tissue type. Thus, regeneration is the only process that directly involves the production of new cells of the same type capable of performing the same specific functions.
