MICROANATOMY

Detailed explanation-1: -Fibroblasts are the most common cell in connective tissue and connective tissues permanent residents. They secrete the fibers (notably collagen and elastin) and ground substance of the extracellular matrix.

Detailed explanation-2: -Growth and Repair. The most common fixed cell of ordinary connective tissue proper is the fibroblast. Fibroblasts are normally quiescent in the adult. During growth and also during repair after injury fibroblasts are active secretory cells which manufacture the fibers and ground substance of connective tissue.

Detailed explanation-3: -To further understand the physiology of connective tissue, it is essential to note the different types of collagen, which are generally composed of fibers found in the extracellular matrix. Collagen is the most abundant protein found in the human body and has 28 types.

Detailed explanation-4: -The extracellular matrix surrounding the fibroblasts is composed largely of collagen fibrils (there are no elastic fibers in the cornea).
