Animal Structure and Function
2
Tissue

• Groups of cells with a common structure and
  function

3
Tissues

• Epithelial Tissue
• tightly packed cells used for lining
• Connective Tissue
• cells scattered through an extracellular matrix
• Nervous Tissue
• transmits signals (neurons)
• Muscle Tissue
• fibers for contraction

4
Epithelial Tissue

• Cell layers
• Simple
• Stratified
• Pseudostratified
• Shape of Cells
