2. Bellwork 9/27
Take out your practice from yesterday so we can review it.
Complete the Epithelial Learning Check. Use your own please. Do not use a textbook, notes, electronic device or your neighbor. This is to see what you know and where you need to go.

3. Announcements Epithelial, Muscle and Nervous Tissue Quiz on Th/F
Cancer Flyer is now Late
Work on your Re-Test Packet – due Monday

4. Agenda 9/27 Learning Goal: Essential Question:
What are the structure, function and location of muscle and nervous tissues?
Review Epithelial Tissues Practice
Muscle and Nervous Tissue Notes
Practice
HW: Reading Notes on ConnectiveTissue
Learning Goal:
Identify and classify Muscle and Nervous Tissue based on their structure, function and location

5. Muscle Tissue
Muscle Tissue
Function
Movement

6. Muscle Tissue Muscle Tissue Location Attached to bone (skeletal)
Walls of hollow internal organs (smooth)
Heart (cardiac)

7. Distinguishing Characteristics
Muscle Tissue
Muscle Tissue
Distinguishing Characteristics
Thin, elongated, cylindrical cells
Elongated nuclei
Contractile

8. How to identify muscle tissue

10. Smooth muscle tissue Makes up walls of hollow organs
Spindle shape, one nucleus per cell
Involuntary

11. Skeletal muscle tissue
Found attached to bone
Long, thread-like cells, multiple nuclei
Voluntary
Fun Fact: Muscle tissue is the most abundant tissue in the human body.

12. Cardiac muscle tissue Found in the heart
Long, striated, branched cells, with one nucleus per cell and intercalated disks joining each cell
Involuntary

13. You Try It! Name the tissue. Smooth Muscle Tissue Is this the
cell membrane,
nucleus,
or cytosol?
Nucleus

14. You Try It!
Name the tissue.
Skeletal Muscle Tissue
How do you know?

15. You Try It! This is Cardiac Muscle Tissue
