From the Textbook
100
These receive synaptic messages from other neurons and communicate this to the soma; some are smooth, some have bumps
What are the dendrites
100
The abrupt, short-lived electro-chemical impulse
What is an action potential
100
This is the study of the effects of drugs on nervous system functioning and human behaviour
What is psychopharmacology
100
This is the fluid filled space between the two neurons
What is the synaptic cleft
100
These are the right and left halves of the cerebrum
What are the cerebral hemispheres
200
These are the endings of the axon branches which release chemicals (neurotransmitters) into the synapses
What are the terminal buttons
200
This is the charge of an axon when it is resting
What is -70 mv
200
These are drugs that facilitate the effects of a particular neurotransmitter
What is an agonist
200
This is what is at the end of the terminal button; these things contain neurotransmitters
What is vesicles
200
This is the formation of new neurons
What is neurogenesis
300
This is the gaps in the myelin sheath along the axon of a neuron.
What is the Nodes of Ranvier
300
This is how neurons transmit signals
What is electrochemically
300
This is what some agonists do to leave the neurotransmitters in the synapse for longer
What is preventing reuptake
300
These cross the synaptic cleft and bind with the post-synaptic neuron
What is a neurotransmitter
300
This is referred to as the "master gland"
What is the pituitary gland
400
This functions as something to increase the speed of an action potential.
What is the myelin sheath
400
This is the chemical charge a neuron has to reach in order for the action potential to be stimulated
What is -65 mv
400
This drug stimulates the release of dopamine & norepinephrine
What is nicotine
400
These are in the cell receiving the impulse; they are chemical gated ion channels
What is neuroreceptors
400
This is a hormone released by the pituitary gland that regulates reproductive behaviours.
What is oxytocin
500
These are the terms used for discussing the number of axons on a neuron.
What is unipolar, bipolar, multipolar
500
This is how fast an action potential can happen
What is 100m/second
500
This is a type of drug that blocks dopamine receptors (preventing the neurotransmitters from working)
What is antipsychotic drugs
500
There are over 100 of these and we are still discovering more
What is neurotransmitter
500
Refers to a long-lasting increase in neural excitability in synapses along a specific neural pathway
What is long-term potentiation
