Skeletal system
- Connective tissue
- Two major types of skeletal connective tissues
Not just a ridged structure:
- Dynamic and active
- Regularly breaking down and regenerating itself
- Forming our blood
, Cartilage Tissue Structure
- Cartilage cells called chondrocytes
- Matrix is flexible gel-like substance and lacks blood vessels (avascular)
Bones
- Average human has - 206 bones
- Range in a large variety of shapes and sizes
Types of bones
