Cartilage and Bone Overview

Hyaline cartilage is the most common type of cartilage in the human body.
The outer fibrous layer of the perichondrium in hyaline cartilage provides structural support and protection to the cartilage.
Chondroblasts, derived from mesenchymal stem cells, are responsible for secreting the cartilage matrix in hyaline cartilage.

Osteocytes and Bone Matrix

Osteocytes, which are mature bone cells, possess a single nucleus located in a small space known as a lacuna.
The primary component of organic material in the bone matrix is type I collagen, providing strength and flexibility.
Osteoclasts are the cells responsible for bone resorption, breaking down bone tissue during remodeling processes.

Genetic Conditions and Cartilage Growth

Osteogenesis imperfecta is a genetic disorder characterized by reduced or defective type I collagen, leading to brittle bones.
Appositional growth is the type of cartilage growth that occurs when new cells are added to the surface of the tissue.

Bone Cells and Their Functions

Osteoblasts are the cells that secrete the bone matrix and deposit calcium salts, playing a crucial role in bone formation.
Sharpey's fibers anchor the periosteum to the underlying bone, providing stability by integrating the two tissues.
Cancellous bone is another name for spongy bone, known for its porous structure that facilitates nutrient exchange and shock absorption.

Learn about the two main types of bone cells - osteocytes and osteoclasts. Osteocytes maintain the bone matrix, while osteoclasts are responsible for bone resorption. Understand their structures, functions, and locations within the bone.
