​

Nervous Tissue

Epithelial Tissue

Purposes?

How many cell types are there? What are they called?

What's the difference between a simple and stratified layer? Benefits of each?

What is polarity?

Connective Tissue

Purpose?

What are they different types?

What is the extracellular matrix (ECM)?

Homeostasis

Control Systems

Describe and provide an example for each of the following:

Negative Feedback

Positive Feedback

Feedforward Regulation

Homeostasis

Control System Components

Define each of the following:
-Set point
-Sensor
-Integrator
-Effector

Surface Area

What is surface area and why might a cell want to increase it?

What is the issue with increasing surface area?

Give an example of how cells effectively increase their surface area

Let's practice!!

Multiple Choice

True or false: there are 5 types of animal tissues

• True

• False

Open Ended

List all 4 types of animal tissues

Multiple Choice

In animals, a sheet of densely packed cells that covers the body, covers individual organs, or lines the walls of various cavities inside the body.

• Epithelial

• Connective

• Muscle

• Nervous

Fill in the Blanks

Since epithelial cells have two sides, one that faces the ECM and one that faces the environment, they are considered to have

Open Ended

List the three epithelial cell shapes

Open Ended

List as many types of connective tissue as you can

Fill in the Blanks

A collection of two or more tissues that performs a specific function or set of functions.

Open Ended

What's the difference between negative feedback, positive feedback and feed forward feedback? Give examples of each

Fill in the Blanks

cell releases molecules that bind to a receptor on the same cell

Fill in the Blanks

Molecules are releases inti interstitial fluid to act on nearby cells

Fill in the Blanks

signaling molecule released from one nerve cell to an adjacent nerve cell

Fill in the Blanks

chemical messengers produced by the endocrine system and secreted into the blood, to act on distant cells
