Cartilage Characteristics

Cartilage is NOT a characteristic of bone tissue.
Cartilage provides a framework for the growth and development of bones.

Types of Cartilage

There are three types of cartilage: hyaline, elastic, and fibrocartilage.
Elastic cartilage contains an abundant network of elastic fibers and is found in the external ear and epiglottis.
Fibrocartilage is found in intervertebral discs and the symphysis pubis.

Cartilage Growth

Cartilage grows through two mechanisms: appositional growth and interstitial growth.
Appositional growth occurs through the formation of new cartilage on the surface of existing cartilage.
Interstitial growth occurs through the formation of new cartilage within existing cartilage.

Bone Tissue

The major organic component of the extracellular matrix of bone tissue is collagen.
Bone tissue forms through two main processes: intramembranous ossification and endochondral ossification.
Intramembranous ossification occurs in areas of ordinary mesenchyme where osteoblasts differentiate directly within richly vascularized connective tissue.
Endochondral ossification involves the invasion of the diaphysis by a periosteal bud containing capillaries, mesenchymal cells, and osteoprogenitor cells.

Bone Growth

Bone growth occurs at the growth plate of long bones.
The growth plate is composed of several zones, including a zone of resting cartilage, a zone of proliferation, a zone of maturation, and a zone of hypertrophy.

Bone Tissue Types

Compact bone tissue has collagen fibers arranged in lamellae.
The rough endoplasmic reticulum is prominent in the cytoplasm of osteoblasts.

Cartilage Functions

Hyaline cartilage provides a framework for the growth and development of bones.
Fibrocartilage is found in areas subject to high stress, such as intervertebral discs and the symphysis pubis.
Fibrocartilage contains type I collagen.
