Bone Structure

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 .
