Studying the microscopic structure of tissues. Objective: To familiarize yourself with the structure of different human tissue types and identify the relationship between their structure and function. Equipment: Microscope, prepared slides of epithelial, connective, muscular, and nervous tissues. Procedure: Cells are tightly packed with little intercellular substance
Set up the microscope and place the slide of epithelial tissue on the stage. Support, transport, nutrition
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
Examine the slide under low and then high magnification. Note how closely the cells are packed.
