: Microscopic structure of tissues (epithelial, connective, muscular, nervous). Lab #2 : Microscopic structure of bones. Lab #3 : Fatigue during static work. Lab #4 : Posture and flat feet. Lab #11 : Effect of saliva enzymes on starch. Example Write-up: Lab #1 "Microscopic Structure of Tissues"
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
This lab is usually the first one students complete in the textbook. laboratornaja rabota po biologii za 8 klass kolesov
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.
Repeat the process for connective (e.g., bone or blood), muscular (skeletal), and nervous tissues. Lab #4 : Posture and flat feet
Examine the slide under low and then high magnification. Note how closely the cells are packed.
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: prepared slides of epithelial
