📖 1. Connective tissues in skeleton

🔑 Key Concepts & Definitions

• Connective tissues are tissues made up of living cells embedded in a non-living intercellular matrix.
• All tissues including bones are called connective tissues because they contain living cells in a matrix.

📝 Essential Points

• The human skeleton is composed of various tissues, including cartilage, tendons, ligaments, and bones, all classified as connective tissues.
• These tissues are characterized by having a small number of living cells within a non-living matrix.
• Cartilage is less rigid than bone tissue, containing specialized cells called chondrocytes within a collagen and elastin matrix.
• All connective tissues, including bones, serve structural and functional roles in the skeleton, supporting movement and stability.

💡 Key Takeaway

Connective tissues are fundamental components of the skeleton, characterized by living cells embedded in a non-living matrix, enabling structural support, flexibility, and movement.
