Synaptic transmission occurs when the neurotransmitter from the presynaptic cell diffuses across the synaptic cleft and binds to its receptors located on the postsynaptic membrane.
Synaptic transmission ends when the dissociates from the receptor and is removed from the synaptic cleft.
The presynaptic neuron releases the neurotransmitter into the synaptic cleft.
A(n) in the axon terminal region causes voltage-gated calcium channels to open.
A neurotransmitter is the chemical signal that opens voltage-gated ion channels.
, or ion movement through chemically gated channels, may depolarize or hyperpolarize the neuron.
Synaptic transmission ends when the neurotransmitter leaves it receptor and is removed from the synaptic cleft.
All neurotransmitters are enzymatically degraded.
The neurotransmitter glutamate is pumped back into the terminal.
The action of the postsynaptic cell depends on which neurotransmitter is involved, and the specific receptor found on that cell.
All acetylcholine receptors produce excitatory postsynaptic potentials.
Acetylcholine binds to more than one type of receptor.
is an example of a neurotransmitter that activates different ion channels resulting in more than one effect on the postsynaptic cell.
There is more than one family of receptors for norepinephrine and epinephrine.
receptors bind norepinephrine and epinephrine.
Cholinergic neurons are only found in the somatic nervous system.
receptors are located in postsynaptic membranes of both preganglionic and ganglionic neurons.
The major inhibitory neurotransmitter in the CNS is glutamate.
Rapid signaling of direct-acting neurons is important for communication, sensory-motor coordination, and other higher order functions.
NE, ACh, and serotonin all produce state changes in the CNS.
Coordinating sensory input with motor outputs requires synaptic signaling.
neurotransmitters can modulate neurons, ultimately changing their functions and producing a new and different output.
