Parts of the Nervous System
Neurons and Neuroglia
Neurotransmitters & Neuron parts
All the Things It Can Do
Action Potential
100
This type of information is sent TO the Brain and is typically sensory information
What is afferent?
100
This neuroglia is the largest one in both number and in size.
What is an astrocyte?
100
This neurotransmitter is the "love" signal.
What is oxytocin?
100
These are the 3 Functions of the Nervous System.
Monitors internal and external environments
Interprets or integrates the information
Coordinates a response (sends signals to body)
100
This is the charge of the axon while AT REST.
What is -70 mV?
200
If you are in fight or flight mode, this system would be activated.
What is sympathetic nervous system?
200
What is a bipolar neuron?
200
This is the space between neurons.
What is the synapse?
200
CSF has these 4 main functions.
What are buoyancy, excretion of waste, endocrine medium, and protection?
200
This is the name for where the line on the graph DROPS. 
What is Repolarization?
300
This part of the nervous system responds automatically, and can be sympathetic or parasympathetic.
What is the autonomic nervous system?
300
These two glial cells have the same job, to create myelin on the axon, to speed up the action potential. One does it only in the PNS, whereas the other only works in the CNS.
What are Schwann Cells and Oligodendrocytes?
300
This neurotransmitter is the reward signal, which is why drugs such as cocaine or alcohol greatly impact it.
What is dopamine?
300
These are the 3 meningeal layers in the CNS in order from the outside in.
Dura Mater, Arachnoid, Pia Mater
300
This ion is moving INTO the axon during depolarization.
What is Na (sodium)?
400
Voluntary control of muscles is part of this system
What is the somatic nervous system?
400
If you are sick, this neuroglia may be found in HIGHER numbers due to its job as a "clean up crew."
What is Microglia?
400
This type of neuron sends information from the internal organs to the brain.
What is interoceptor?
400
This spinal cord root will send sensory information to spinal cord and then up to the brain.
What is the motor root?
400
This ion is found INSIDE the Axon while at rest.
What is K (potassium)?
500
Sensory information is usually this, while motor information is usually this.
What is afferent and efferent?
500
This neuroglia makes and circulates CSF.
What are ependymal cells?
500
This is a change in behavior based on new information
Learning
500
This bypasses the brain, taking in sensory information and coordinating a motor response without consulting the brain first.
What is a monosynaptic reflex?
500
The ______ channel closes, and then the ____ channel opens at the PEAK of the Action Potential graph.
Sodium closes, Potassium opens
