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:

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 For any lab from the Kolesov textbook ,

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. Repeat the process for connective (e

Examine the slide under low and then high magnification. Note how closely the cells are packed.
