The pain in the leg that is referred to as "shin splints" is often caused by microtears in the periosteum and perforating fibers. These tears lead to inflammation of the periosteum. Considering the type of tissue found in the periosteum, which cells do you think would be most involved in the repair process?

Osteoclasts

The periosteum is the membrane that serves to line the bones. The membrane consists of connective tissue, osteoblast cells, and osteogenic cells. Osteogenic cells and osteoblasts are involved in the growth and repair of bones as well their the nutrition of bones.

The connective tissue of periosteum consists of cells such as fibroblasts which in turn are the large and immature cells involved in secretion of fibers, ground substances and most of the extracellular matrix of the connective tissues. Therefore, the tearing of the periosteum would be repaired with the help of fibroblasts.

Connective tissue is mainly composed of fibroblasts. They maintain the tissue structure and are involved in healing processes. Fibroblasts are the cells involved in the repair process. Option A is correct.

What is the periosteum?

The term periosteum refers to the thin layer of connective tissue that surrounds or covers the bones.

This membrane is highly vascularized, fibrous, and resistant.

What is the composition of the periosteum?

Two layers compose the periosteum: the outer fibrous one and the inner replacement one.

The external fibrous layer is composed of fibroblasts.

The rechange layer has progenitor cells that turn into osteoblasts and condroblasts, responsible for the increase of bone and cartilage thickness.

The periosteum also has nociceptive nerve endings, which make it very sensitive.

It also has vascular spaces through which veins can pass to nourish the internal part of the bone.

What is a fibroblast?

Connective tissue is mainly composed of fibroblasts.

These cell's function is to synthesize and maintain the extracellular matrix. Fibroblasts secrete collagen proteins that are used to maintain the structure of many tissues.

These cells are also involved in the wound healing processes.

Fibroblasts are then the cells involved in the repair process. Option A is correct.

Chondroblasts, Osteoblasts, and Osteoclasts are cells involved in cartilage and bone growth and healing.
