DPT 505 Neuroscience (Synaptic transmission and
neurotransmitter) || All Answers Are Correct 100%.
How many synapses can each neuron make? correct answers As many as 100,00 synapses
How many neurons are in the brain correct answers 85 billion neurons
How do most of the neurons transmit information? correct answers Chemical signals with the aid
of neurotransmitters
Where are the neurotransmitters released from? correct answers Synaptic cleft
How many neurotransmitters have been identified? correct answers Over 100
T/F Neurons have receptors for one type of neurotransmitter? correct answers False
How do drugs that treat neurologic disease work? correct answers Either enhance or reduce the
ability of neurotransmitters to interact with the post-synaptic receptor
What do synapse allow communication with? correct answers Communication between neuron
and post-synaptic cell
Neurons, organs, glands, blood vessels, muscle cells
What are synapse composed of? correct answers Pre-synaptic/post-synaptic terminal
Synaptic cleft
What type of signal can the synapse transmit correct answers Chemical or electrical
The small number of synapses that are just electrical synapses are called correct answers Gap
junction
T/F there is no space between electrical pre and post synaptic membranes correct answers True
T/F The electrical pre-synaptic cell releases neurotransmitters correct answers False(It does not)
In the electrical synapses, is communication one way or bidirectional correct answers
Bidirectional
What is the benefit of signaling in electrical synaptic transmission? correct answers Fast
Helps synchronize sets of neurons
5 steps of chemical transmission correct answers Synthesis
Storage
Release
Reception
, Inactivation
When is an action potential triggered correct answers Only when the axon hillock reaches its
threshold
What occurs when NTs bind to a receptor? correct answers Creates a flow of ions into post-
synaptic cell
Thus changing the post-synaptic potential
Is it true that post-synaptic potential can be either excitatory or inhibitor? correct answers True
What causes an action potential? correct answers Sufficient positive electrical response
# of signals acting on a post-synaptic neuron? correct answers Multiple
What do the signals on the post-synaptic neuron dependent on? correct answers Dependent on
the summation of the net results of the excitatory/inhibitory inputs
What are the types of synapses correct answers Axodendritic
Axosomatic
Axoaxonic
What is convergence correct answers Single neuron receives thousands of inputs from other
neurons
What is divergence? correct answers Single neuron synapses with thousands of other neurons
T/F NTs can only bind with specific receptors correct answers True
T/F Each NT doesn't have multiple receptor types correct answers False
Do neurons have receptors? correct answers Yes, they have multiple different receptors so
neurons can respond to a variety of NTs
Where are NTs and receptors found? correct answers Different parts in the brain, also different
NTs and specific receptors for these different parts
What allows for the different/unique behaviors for different areas of the brain? correct answers
Different combination of NTs and receptors
What is embedded in the post0synaptic neuronal membrane? correct answers Proteins
Post-synaptic receptors are activated by correct answers Neurotransmitters
Two classes of Post-synaptic receptors correct answers Ionotropic
Metanotropic
