What parts make up the central nervous system?
brain
spinal cord
autonomic nervous system
somatic nervous system
Part of the nervous system that extends out from the spinal cord to the rest of the body
central nervous system
peripheral nervous system
brain
cerebral cortex
Nerve cells that run through our entire body that send and receive messages with each other; look like trees
neurons
dendrites
axons
synapses
The part of a neuron that receives information from other neurons and passes it along through the cell body
synapse
dendrite
axon terminal
cell body
The part of a neuron that transmits messages away from cell body; covered by myelin sheath
synapse
dendrite
axon
axon terminal
The part of a neuron that covers the axon; helps speed up the the transmission of message; white fatty substance that also insulates the axon
synapse
dendrite
myelin sheath
axon terminal
Part of a neuron gaps in the myelin sheath that don't cover the axon.
synapse
Schwann cell
nodes of Ranvier
axon terminal
Small fibers branching out at the end of a neuron that send messages out to other neurons
synapse
Schwann cell
nodes of Ranvier
axon terminal
The area between the axon terminals where messages are sent and dendrites that receive the message
synapse
Schwann cell
nodes of Ranvier
cell body
Chemical messengers that carry impulses across the synaptic gaps between neurons
neurotransmitters
neurons
Schwann cells
reticular activating system
Match the neurotransmitter with the correct function
acetylcholine
helps control muscles; used in learning
dopamine
involved in reward and pleasure
noradrenaline
regulates mood and stress response
serotonin
contributes to sleep, hunger, and mood
Match the following
Regulates things you control; enables us to feel things and move muscles
somatic nervous system
Regulates things you don’t control; heart rate, blood pressure, digestion, breathing, etc…
autonomic nervous system
Goes into action during stressful events
(fight or flight)
sympathetic system
Calms body down after emergencies
(rest & digest)
parasympathetic system
Put the following in the correct category
brain
spinal cord
autonomic system
somatic system
sympathetic system
parasympathetic system
Order the parts of the brain from smallest to largest
midbrain
hindbrain
forebrain
Put the parts of the brain in the correct area
medulla
pons
cerebellum
thalamus
reticular activating system
hypothalamus
limbic system
cerebrum
part of the reticular activating system
Wrinkled outer layer of the brain – like bark on a tree; has ridges and valleys
cerebral cortex
corpus callosum
limbic system
reticular activating system
Structure that connects the two hemispheres of the brain
cerebral cortex
corpus callosum
limbic system
reticular activating system
Which of these is NOT a device that provides images of the brain?
The incorrect answer records the electrical activity of the brain - no image
EEG - Electrencephalograph
CAT scan
MRI
PET scan
What functions are more closely related to each particular part of the brain?
language ability (most righties & 2/3 of lefties)
logic
facts
problem solving
math
imagination
art
feelings
creativity
directions & spatial awareness
Info received on one side of the body is sent to the (a) hemisphere of the brain
Which of the following are ways scientists study how our brains work?
accidents
electrical stimulation
brain imaging (MRI, CT/CAT, PET scans)
personality tests
