WebMar 17, 2024 · Hyaline Cartilage. This is the most common form of cartilage in the body and also the weakest type. It is mostly made up of collagen (type II) with relatively few elastic fibres and is surrounded by a perichondrium. Hyaline is a precursor for bone and so is found in the epiphyseal growth plates of children.
