Difference between Fibrocartilage and Hyaline Cartilage

Fibrocartilage

It is a proportional mixture of cartilaginous tissue and fibrous tissue. Thus, they are a little tough and inflexible. This cartilage is composed of type Ⅰ and Ⅱ collagen, which provides elasticity. It is strong and has a dense layer of collagen fibres. Fibrocartilage is seen in the glenoid labrum, acetabular labrum, menisci, pubic symphysis, etc. Also, in the places where the ligaments and tendons attach to bone.

Hyaline Cartilage

It is a translucent cartilage that is present on many bone joints. Hyaline cartilage is a firm structure that has collagen. It is a simple structure with no blood vessels or nerves. It is seen in the nose, ribs, trachea and larynx.

Hyaline cartilage is enveloped by a fibrous perichondrium membrane or synovial membrane. The membranes facilitate diffusion, and thus supply the cartilage with nutrients.

Fibrocartilage

Hyaline Cartilage

It is a mixture of cartilaginous tissue and white fibrous tissue.

It is a translucent cartilage that is present on many bone joints.

It has type Ⅰ and Ⅱ collagen.

It has type Ⅱ collagen.

It is strong cartilage with a dense layer of collagen fibres.

It has less collagen and is comparatively weaker cartilage.

The perichondrium layer is absent.

The perichondrium is present (except articular hyaline).

It is seen in the glenoid labrum, acetabular labrum, menisci, pubic symphysis, etc.

It is seen in the nose, ribs, trachea and larynx.

Frequently Asked Questions

What is articular cartilage?

It is a type of hyaline cartilage that is present on the articular surfaces of the bone joints. These cartilage are usually covered by the synovial membrane, and are soaked in synovial fluid.

What is elastic cartilage?

It is a yellow cartilage that makes up the ear pinna. It is composed of a key protein called elastin. Its microanatomy is somewhat similar to the hyaline cartilage.

What is perichondrium?

It is a layer of connective tissue that envelopes the cartilage of bones. Perichondrium has a fibrous layer composed of collagen fibres and fibroblast. Also, it has an inner undifferentiated chondrogenic layer. This perichondrium is seen in hyaline and elastic cartilage. It is absent in articular and fibrocartilage.
