Fibroblasts are typical cells that lead to stromal repair in an organ. Fibroblasts play a critical role in healing wounds and are the most common cells found in connective tissue. These cells are long flat elongated cells. They secrete both several types of protein as well as ground substance.

The different types of protein they secrete include collagen, elastin, reticular fibers, and fibronectin. Fibroblasts end up creating an extracellular matrix of connective tissue. Even cartilage is a specialized example of a fibroblast.

Connective tissue develops from the mesoderm on any animal tissue that can be found in between tissues all over the body. Epithelial tissue, on the other hand, is located on the organs’ blood vessels and outer surfaces. Connectives tissues help in protecting and supporting the body while epithelial tissues help in absorption of nutrients to the body.

Epithelial tissues can be found in the kidneys, lungs, and skin while the connective tissues can be found in ligaments, nerves, and bones. Epithelial tissues are surrounded by blood capillaries that allow them to absorb the nutrients from what we consume. The epithelial tissues are not surrounded by blood capillaries that mainly protects the cells and the organs they surround.

When someone contracts a myopathy, he or she will struggle with movement.

They might have trouble grabbing a glass off the counter. This is because the skeletal muscles might be struggling with contraction. When the skeletal muscle can’t contract, then the tendon then can’t move the bone. The tissue that connects the muscles is called fascia. There are also muscle fibres in the muscles.
