Tissue Types…
4 types of tissue
1. Muscle Tissue
2. Nervous Tissue
3. Epithelial Tissue (skin)
4. Connective Tissue

Connective Tissues
• Includes– Tendons – Ligaments – Bones

Connective Tissue
• Tendons – Connect muscle to bones.
– silvery-white tissue at the ends of the muscles – Non-elastic = muscles contract and tendons
pull the bones causing movement.

Connective Tissue
• Ligaments – Connect bones at joints .
– Elastic to allow
For movement

Joints and Cartilage
• Joints – Places where bones meet.
• Cartilage – firm tissue at the ends of bones.– Glossy white, protects and lubricates bones at
joints.

Skeletal Muscles
• Muscles are connected to bones by tendons.
• ONLY pull or contract.
• Work in opposing pairs.
