Neurons
What is the space between a presynaptic and post synaptic neuron called?
Synapse, Synaptic Gap, Synaptic Cleft
Where are the neurotransmitters found in a neuron?
Terminal buttons
This type of drug is most likely to cause an action potential?
Agonist
Which parts of the body are associated with the Central Nervous System?
brain and spinal chord
A neuron will either respond fully or not at all to a stimulus, regardless of the stimulus's strength or duration. This principal is called the
All or None Principle
When the inside of a neuron has a higher concentration of negative ions than the outside and is not firing we call the state
Resting Potential
Which type of neurotransmitter is most likely to cause an action potential?
Excitatory
This agonist mimics your body's endorphins and can dull the perception of pain
Which part of the nervous system is also referred to as "rest and digest"
Parasympathetic nervous system
What type of neuron connects a sensory neuron to a motor neuron?
Interneuron
The time shortly after a neuron fires, and cannot fire again is called the
Refractory Period / hyperpolarization
Which neurotransmitter is most associated with motivation, addiction, reward and learning?
Dopamine
Medicine such as Advil or Tylenol are analgesics which block or inhibit the transmission of pain. A drug that blocks a message is known as
Antagonist
When this part of the autonomic nervous system is activated, your heart rate increases, pupils dilate, and your saliva production is inhibited
Sympathetic Nervous System
What is the name of the covering of some axons especially in the peripheral nervous system? They insulate the axon and speed up messages.
Myelin Sheath
The level of stimulation required to trigger an action potential in a neuron (usually -55mV) is called
Threshold, Threshold of Excitation
Which neurotransmitter is associated with depression?
Serotonin
Which psychoactive drugs decrease nervous system activity?
depressants
The Peripheral Nervous System is split into these two parts
autonomic and somatic
The process in which transmitter molecules are recycled back to the terminal buttons of the sending neuron
Reuptake
During an action potential, the electrical state of the axon changes to become
depolarized / negative to positive
What neurotransmitter is associated with memory deficits especially the formation of new memories?
Acetylcholine
This drug increases the serotonin in your synapse by blocking the reuptake process, helping individuals with depression
SSRIs
What type of signal is transmitted from sensory neurons to the brain?
Afferent signals
Which neurotransmitter is known as your neural brake and is the main inhibitory neurotransmitter?
GABA
