Which is the middle layer of the meninges?
Which space is located between the dura mater and the skull?
Epiarachnoid space
Subarachnoid space
Epidural space
Subpial space
Specialized endothelial cells that have tight junctions and prevent the movement of materials from the blood into the brain
meninges
blood-brain barrier
cerebrospinal fluid
epidural space
Identify this space within the vertebrae through which the spinal cord passes
foramen magnum
vertebral foramen

Cerebrospinal fluid is secreted by
Choroid plexus
Arachnoid
Dura
Pia
pertaining to below the dura mater, tumor of blood
cerebellitis
cerebral thrombosis
subdural hematoma
rhizomeningomyelitis
An infection induced inflammation of the meninges surrounding the brain and the spinal cord
epilepsy
meningitis
dementia
cerebral palsy
A mild or severe trauma that can result from a
violent impact to the head
epilepsy
Traumatic brain injury
dementia
multiple sclerosis
Select 3 symptoms of MTBI (Mild Traumatic Brain Injury).
headache
memory loss
fainting
nausea or vomiting
What is the best way to prevent TBI?
Wear a helmet, Wear a seat belt in the car, No texting while driving, Wear protective gear when playing a sport
Don't play sports ever again
Eat a lot of ice cream
Make sure you wear a helmet all day every day.
How do you get a TBI?
When an object hits you in the head or you hit your head in an object
A large jolt to the head such as an explosion
A motor vehicle crash
All of the above
What is the difference between a Mild TBI and a Severe TBI?
A mild TBI is deadly and a Severe TBI is harmless. A mild TBI kills 100 billion people each year in the USA but the Severe TBI only kills 1 thousand.
There is no difference, they are both the same.
A Mild TBI can cause headache, Dizziness, balance, and coordination problems. A Severe TBI can cause light sensitivity, sound sensitivity, and/or seizures.
All of the above
What happens inside your brain when you get a TBI?
When you get a TBI your brain moves inside your skull and that can cause damage to the main lobes of the brain.
When you get a TBI you could tear the tissue in your brain. It could also cause other physical damage to the brain such as bleeding.
When you get a TBI you can experience a loss of consciousness or memory loss of the event.
All of the above

synaptic cleft
Chemicals released into a cleft when an action potential reaches the terminal are called.....
ligand gated ion channels
synaptic vesicles
neurotransmitters
voltage gated ion channels
Which pattern shows how signals are transmitted from the presynaptic neuron to the post synaptic neuron
electrical --> electrical
electrical --> chemical
chemical --> electrical --> chemical
electrical --> chemical --> electrical
Which side of the synapse contains neurotransmitters?
presynaptic
postsynaptic
both
What causes the release of neurotransmitters into the cleft?
an action potential reaches the terminal
ligand gated ion channels open
excititory neurotransmitters bind to ligand gated ion channels
an action potential on the post synaptic neuron triggers nearby voltage gated ion channels
Drugs have their effects because they
mimic some neurotransmitters
cause neurotransmitters to be released without a signaling action potential
block the re-uptake of some neurotransmitters
cause action potentials to move in reverse along the axon
What chemical is activated by the action potential in the presynaptic neuron that causes the vesicles containing neurotranmitters to move toward the synaptic cleft?
calcium
potassium
sodium
phosphorus
Type of synapse which increases the chance of the next neuron firing
Inhibitory
Excitatory
Neurotransmitters
Neuron
Type of synapse which decreases the chance of the next neuron firing
Inhibitory
Excitatory
Neurotransmitters
Neuron

Serotonin and Dopamine
Dopamine and norephinephrine
GABA and Serotonin
GABA and Dopamine
Both Parkinson's Disease and Schizophrenia are associated with dysregulation of...
GABA
Dopamine
Seratonin

Antagonist
A chemical that mimics or enhances the effect of a neurotransmitter:
Agonist
Antagonist
