Anatomy
What is anatomy?
The study of the structures of our bodies
Why is lab safety important?
It helps us stay safe and prevent accidents and injuries
What is the name of the chemical signals and messages neurons send to the brain?
Neurotransmitters
What are enzymes?
Proteins made by our cells
What part of the circulatory system carries blood towards the heart?
Veins
What three pieces of personal protective equipment (PPE) do we wear in the lab?
Lab coats, gloves, and safety goggles
What are the three main parts of a neuron?
Dendrite, axon, and cell body
What important role do enzymes play in our bodies?
They act as catalysts
What are the three parts of the respiratory system?
Lungs, airway, and diaphragm
When should you wear safety glasses in the lab?
Always
Which part of the neuron receives signals and which part releases signals?
The dendrite receives signals and the axon terminal releases signals
What is a catalyst?
A catalyst is a compound that helps to get a reaction started and makes it go faster
What are the four chambers of the heart?
Right ventricle, right atrium, left ventricle, and left atrium
Name two of the rules for being safe in the lab.
No food or drink, wear PPE, listen to instructions, keep your space clean
Name three of the five neurotransmitters that we talked about.
Dopamine, acetylcholine, serotonin, glutamate, and GABA
What enzyme did we look at in our experiment?
Catalase
What are the three steps for breathing?
Step 1: the diaphragm moves down and air comes into the airway and lungs where oxygen moves to your blood
Step 2: carbon dioxide moves from your blood into the lungs and is exhaled
Step 3: the diaphragm relaxes
If an accident happens in the lab, what is the first thing you should do?
Notify the instructor
What do inhibitory neurons do?
They stop neurotransmitters from being released
What are the three steps for how an enzyme works?
Step 1: the substrate binds to the active site
Step 2: the reaction takes place
Step 3: the products are released from the active site
