Muscular And Nervous Tissue Lab

Name ______________________ Muscular Tissue and Nervous Tissue Lab Pre-Lab 1. What does muscular tissue do for the body? __________________________________________________________________________ 2. What is the purpose of nervous tissue?

___________________________________________________________________________ 3. Name the three types of muscular tissue.

___________________________________________________________________________ Lab It is your responsibility to draw your tissues carefully. This is a lab grade and the drawings will be graded for neatness and accuracy. You will use these drawings (and links on my website) to study for the lab practical portion of your test. Procedure: 1. Go to your assigned station in the lab. 2. Use your time wisely. You will see a tissue sample under the microscope. DRAW EXACTLY WHAT YOU SEE. There should be NO NEED TO ADJUST THE COARSE ADJUSTMENT KNOB. If you field of view is unclear, you should use the fine adjustment knob only. 3. You will have 7 minutes for you and your partners to look at and draw what you see in your field of view. 4. Label a cell for the nervous tissue, striations for skeletal muscle, nucleus for smooth muscle and intercalated disks for cardiac muscle. 5. When time is up, you will move to the next station. 6. If 7 minutes is not ample time for your group, you will have time to come back to any that you need extra time. Data: Station #1
