TISSUE LAB

Tissue Lab
w/focus on Epithelial & Connective Tissues

Talk with your table about something good that's happened to you this week!

​

At Your Table...

examine epithelial, connective, muscle, and nervous tissue characteristics and view them microscopically

I will...

compare & contrast the structure & function of all 4 categories of tissues found in the human body

We will...

These are tissues that line and cover our bodies. For the microscope, look at the EDGE of the specimen (the APICAL SURFACE AREA).

Where to Find Them?

Cuboidal tissues will be located within the specimen. Their apical surface area is the lumen inside their cell area

But then there's cuboidal...

When you get your specimen zeroed in, use your phone to take a picture of it so you can draw it later. Don't forget to label!

​​Take a pic!

​EPITHELIAL TISSUES

Multiple Choice

Find the SIMPLE SQUAMOUS tissue:

Multiple Choice

Which organs contain most of the cuboidal tissues in the body?

• Kidneys & Bladder

• Heart

• Liver

• Skin

Match

Match the following tissue types

Simple Columnar

Simple Squamous

Simple Cuboidal

• Simple Columnar

• Simple Squamous

• Simple Cuboidal

Open Ended

What is the importance of having pseudostratified epithelia lining your trachea? Why not simple squamous or cuboidal?

Talk with your table/neighbor about something you learned about epithelial tissues

​

At Your Table...

examine epithelial, connective, muscle, and nervous tissue characteristics and view them microscopically

I will...

compare & contrast the structure & function of epithelial and connective tissues specifically.

We will...

Connective tissue do just that-they "connect" other tissues together. Think about what all is connected inside of your body

Where to Find Them?

Blood is a tissue and a connective tissue at that! How does it "connect"?

There's always an oddball...

When you get your specimen zeroed in, use your phone to take a picture of it so you can draw it later. Don't forget to label!

CONNECTIVE TISSUES

Open Ended

How do you think blood is a "CONNECTive" tissue:

Open Ended

Notice the nuclei pushed to the outside of the adipose cell

WHY IS THAT?

Describe why the nucleus it is not centrally located within the adipose cell:

• Several of your ligaments, such as the ligaments in your knee (ACL, MCL, etc) are twisted elastic connective tissue

FUN FACT: ​The fibers of the ACL and PCL ligaments are wound in a spiral pattern to withstand the twisting & pulling of the knee. In contrast, the fibers of the MCL and LCL pass more straight from bone to bone along the sides of the knee joint.

Open Ended

What advantage would a "twisted" elastic tissue give you over one that is not?

​BLOOD CONNECTS TO EVERYTHING IN YOUR BODY!
