Draw a representative section of each tissue in your notebook and label the main components (nucleus, cytoplasm, cell membrane). Summary Table (Example): Tissue Type Structural Features Epithelial Lab #2 : Microscopic structure of bones

Cells are tightly packed with little intercellular substance. Protection, secretion, absorption. Cells are widely spaced with lots of intercellular matrix. Support, transport, nutrition. Muscular Elongated cells (fibers) capable of contraction. Movement of body parts. Nervous Neurons with long and short processes. Reception and transmission of impulses.

Set up the microscope and place the slide of epithelial tissue on the stage.

Each tissue has a unique structure that corresponds strictly to its function. For example, the tight packing of epithelial cells provides a protective barrier, while the long processes of neurons allow for signal transmission across distances. General Write-up Tips
