What type of cell bodies are found in the cell-rich/free zone of Weil?

Adipocytes
Fibroblasts
Neurons
Macrophages

The correct answer is: Fibroblasts

The cell-rich/free zone of Weil is an area within the periodontal ligament that contains a significant number of fibroblasts. These fibroblasts are crucial because they play an essential role in the maintenance and remodeling of the extracellular matrix in periodontal tissues. They are responsible for synthesizing collagen and other fibers that provide structural support to the periodontal ligament, contributing to the overall health and stability of the tooth in its alveolar socket. This zone is characterized by a high turnover of cells that help in tissue repair and regeneration, which is primarily facilitated by fibroblasts. The presence of adipocytes, neurons, or macrophages is not typical for this specific area, making fibroblasts the most relevant and correct choice.
