GENERAL HISTOLOGY

Detailed explanation-1: -Loose and dense connective tissue are made up of the following three fibers: collagen fibers, reticular fibers, and elastin fibers.

Detailed explanation-2: -A diagram of a collagen molecule. Collagen is the most common fibrous protein in the ECM, and it isi important for resisting tensile forces. It is the most abundant protein in mammals-25% of total protein mass! It is a protein composed primarily of the amino acids glycine & proline, and it also contains sugar groups.

Detailed explanation-3: -Type III collagen is found as a major structural component in hollow organs such as large blood vessels, uterus and bowel, tissues that must withstand stretching. It is also found in many other tissues in association with type I collagen.

Detailed explanation-4: -Types. There are close to 30 different types of collagen that have been identified so far. The most abundant type of collagen present in the human body is that of Type I (over 90% of the collagen in the body being type I) with significant amounts of Type II, III and IV also accounted for.

Detailed explanation-5: -Type I. This type makes up 90% of your body’s collagen. Type II. This type is found in elastic cartilage, which provides joint support. Type III. This type is found in muscles, arteries and organs. Type IV. This type is found in the layers of your skin. Type V.
