MusculoSkeletal How to remember the Types of Collagen

How to remember the four major types of collagen?

the higher number you go the weaker it goes


Type I is the strongest as it is located in bones, skin, tendons, fascia, cornea, teeth and mature scars.

Type II little bit less strength seen in cartilage, vitreous humor, and nuclus pulposus

Type III goes even weaker as it is present in granulation tissue, embryonic tissue, uterus, blood vessels, and keloids.

Type IV is the weakest is it only supports a row of epithelial cells as it's found only in basement membranes.

Wink Type 1 n 2

  • bONE is made of type ONE collagen;
  • CARTilage is made of type two collagen. Alternatively remember carTWOlage.
  • Still if you find it confusing remember B of bone comes before C of cartilage; B-1, C-2.
