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. 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.
