The long fibres of protein found in the extracellular matrix that provide structural support for cells are called microtubules. They are hollow rods that are essential to cell shape and support.
The most common cells found in connective tissues are fibroblasts. These cells are responsible for producing and maintaining the extracellular matrix components such as collagen, elastin, and ground substance, which provide support and structure to the tissue.
Connective tissues primarily develop from the mesoderm germ layer. The mesoderm gives rise to various connective tissue types, including bone, cartilage, blood, and adipose tissue. Some connective tissues, like those found in the head, may also have contributions from the ectoderm and neural crest cells, but the mesoderm is the principal source for most connective tissues in the body.
Collagen is the fiber type that gives connective tissue great strength. It is the most abundant protein in the human body and provides structural support and tensile strength to tissues such as tendons, ligaments, and skin.
A fibroblast is a type of cell that synthesizes the extracellular matrix and collagen, the structural framework (stroma) for animal tissues, and plays a critical role in wound healing. Fibroblasts are the most common cells of connective tissue in animals.

A fibroblast is cell that makes scar tissue, and that can be anywhere in the body.
The most widely distributed tissue type in the body is known as the connective tissue.
Yes, most connective tissues arise from mesenchyme, an embryonic tissue. Mesenchyme gives rise to fibroblasts, which then differentiate into various types of connective tissue cells and produce the extracellular matrix. However, some specialized connective tissues like blood and lymph do not directly arise from mesenchyme.
Connective tissue hold structures together.
