Behavior Science & Research Design
Abyan was reading a book about brains and had an idea that specific functions come from specific regions
What is Localization?
Central(brain & spinal cord) and Peripheral(nerves running through the body & has 2 sub div.) nervous system
What are the 2 major divisions of the nervous system?
Iman had a sudden short episode of intense fear that triggered severe physical reactions
What is Anxiety?
The magic school bus followed the chemical signal to deliver a message, but they came to a sudden stop at the bottom of the nerve cell! For some reason there was a gap not allowing them to go to the other side. That gap is a ____
What is a Synapse?
TRUE or FALSE:
Astrocytes are part of the microglia category
FALSE:
they are part of the macroglia -
work to support neurons, repair damage, regulate neuronal communication, and maintain blood-brain barrier
While playing charades, we had to act out something that has gray matter outside and white matter in the middle. Has bumps & grooves, and is sectioned into lobes
What is the brain?
PNS sub divisions:
1. has nerves that carry sensory signals
2. Regulates the body(digestion & Heartbeat)
1. What is the Somatic nervous system?
2. What is the Autonomic nervous system?
Two students were debating. Arnold said all animals have brain. Phoebe said no. What example can Phoebe use to build her argument and if the animal doesn't have a brain, what does it have?
Jellyfish and they have nervous nets
If this thing breaks down/ stops working, a stroke may occur because this the basic unit of the nervous system
What is a neuron?
What are the 2 types of Glia & their function?
Macroglia-
Microglia- primary immune defense of CNS; remove damaged neurons, pathogens, and other foreign substances
Medical student Franz Gall was running around trying to introduce a theory of his, that traits come from the shape of the skull
What is Phrenology?
Magic school bus took a trip into the brain and found something that has layers of tissue between the brain & skull. Ms.Frizzle gave the students a hint that it had a Dura, Arachnoid, and Pia mater
What is Meninges?
Looking at images of the brain, Ralphie noticed it actually has 3 major parts, an oval, a small circle under it, and a long cylinder sticking out the oval. Name all 3 underlined parts
What is the Cerebrum?
What is the Cerebellum?
What is the BrainStem?
Name the 3 types of neurons
What is a sensory neuron?
What is a motor neurons?
What is an interneuron(intermediate)?
Which two Macroglia are responsible for producing/covering neurons with myelin(insulatory material)?
Oligodendryocytes(CNS)
Schwann cells(PNS)
Researchers conducted a track experiment. They had same mile time, but for the experiment one had to sprint while the other jogs. The sprinter one broke a leg. What is the IV and DV in this experiment.
IV: speed
DV: leg broke
If someone is in danger, this nervous system division will cause their heart rate and blood pressure to increase and create sweat glands( FIGHT or FLIGHT)
These things are similar to what happens to a tooth. In which "cavities" arise, except they are in the brain and are filled with fluid.
*CSF = cerebro-spinal- fluid* Protect, extert, buoyance, and transport
What are Ventricles?
Some students were playing outside, and all of a sudden a ball that was thrown is coming for Ms.Frizzle, without thinking she ducks. What is her reaction?
A reflex
The magic school bus arrived at the walls of the ventricles and found the cells that produce cerebrospinal, protect the brain from injury, and remove waste products. What is the name of the cells they found?
Ependymal Cells
1.manipulating the body may affect behavior
2.Body & behavioral measures covary
3.Experience affects the body, including the brain
1. What is Somatic intervention?
2. What is correlations?
3. What is behavioral interventions?
When Aya breaks her fast, this system will simulate digestion, increase her saliva production, and slow her heart rate: She calls it "REST & DIGEST"
What is the Parasympathetic nervous system?
1. Where is the Dorsal located?
2. Where is the Ventral located?
3.Where is the Anterior located?
4. Where is the Posterior located?
5. Where is the Medial located?
6. Where is the Lateral located?
1. up
2. down
3. in front
4. Behind
5. towards the middle
6. Towards the sides
Name 5 parts of the Neuron and their functions
Dendrites - where inputs are received Cell membrane- protects cell Cell body(soma): nucleus- integrates incoming info
Axon - Highway for 1 way electrical signals Node of Ranvier allows ions to go in & out(gatekeeper) Myelin sheath allow electrical impulses to transmit fast Synapse: gap chemical messages must pass
Frontal lobe, Temporal lobe, Parietal lobe, Occipital lobe
What are the four sections/divisions of the Brain?
