Nervous Tissue
Epithelial Tissue (skin)
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.
