Animal Cell
Red blood cells are special cells that do not have a nucleus, which allows them to travel through your body easier. This means that they are missing what?
DNA
In what type of connective tissue do we store fat molecules?
Adipose
What type of epithelial tissue are common at the sites of diffusion and filtration?
Simple squamous
All three epithelial membranes are composed of what two components?
Epithelial tissue and connective tissue
What are the three components of a homeostatic mechanism?
Effector, Receptor, and Set Point
Whenever you move, you are using your muscles. Muscle cells are specially designed to use an enormous amount of energy. Which organelle do they have more of?
Mitochondria
What is the extracellular matrix?
The space between cells!
What is the name of the structure that all epithelial tissues are connected to?
Basement membrane
What membrane secretes a watery fluid that lines our internal organs?
Serous membrane!
What is the feedback mechanism that seeks to return to the set point by reversing change?
Negative feedback
What contributes to the inside of the cell being described as a "fluid-mosaic model"?
The cytoplasm
What is the purpose of areolar connective tissue?
Bind skin to internal organs
What makes pseudostratified cells not really considered to be layered?
All cells touch the basement membrane
Which membrane lines cavities and tubes that open to the outside of the body?
Mucous membrane
What is the feedback mechanism that seeks to return to the set point by adding onto the already present change?
Positive feedback
The cell membrane is designed to allow molecules to pass through, either alone or with the help of special proteins. What word best describes the cell membrane?
Semi-permeable
Marny doesn't like how her skin looks and wants to get rid of her wrinkles. She decided to go to Ulta and get collagen cream. Will this help her (physically, not emotionally)?
No! Collagen molecules are too big to pass through the skin!
What are Goblet cells?
Cells that produce mucous
What is another name for the cutaneous membrane?
The skin!
When you get too hot and start sweating, which feedback mechanism is this an example of?
Negative!
What is the name of the proteins that float around the cytoplasm, are the main components in protein productions, and catalyze reactions?
Ribosomes!
What do fibroblasts do?
Secrete Fibers!
With which type of epithelial tissue do we see keratinization occur?
Stratified squamous
Why is the Synovial membrane considered a minor membrane? Where is it located?
It is only made up of connective tissue and lines the joints!
When you begin to give birth, your body releases the hormone oxytocin. In response, your body releases more oxytocin to increase contractions, which eventually leads to birth. Which feedback mechanism does this represent?
Positive!
