A neurotransmitter binds to specific receptors on the postsynaptic membrane of a receiving neuron, leading to the opening of ion channels. This causes an influx of positively charged ions, such as sodium (Na+), which depolarizes the membrane. If the depolarization reaches a certain threshold, it triggers an action potential by opening voltage-gated sodium channels, allowing further sodium influx and propagating the electrical signal along the neuron.
No, neurotransmitters do not create new action potentials. They transmit signals between neurons by binding to receptors on the receiving neuron, causing a change in the membrane potential of the receiving neuron which may lead to the generation of a new action potential.
Every time neurotransmitter is released from the presynaptic neuron it generates an excitatory post synaptic potential(EPSP) in the postsynaptic neuron. When the EPSP is greater than the threshold for excitation an action potential is generated.
When an action potential reaches the axon terminal of the presynaptic neuron, it triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the postsynaptic neuron, leading to changes in its membrane potential. This process either excites or inhibits the postsynaptic neuron, depending on the neurotransmitter and receptor type involved.
When the _____________reaches the ends of the axon the neurotransmitter is released and it diffuses to the muscle cell membrane to combine with receptors there?Sarcolemma
By a chemical released by an axon.
Increases, leading to more neurotransmitter release at the synapse. This can result in a stronger postsynaptic response in the receiving neuron.
The receiving neuron is less likely to generate action potential.
When a signal is sent out from the nervous system it is caused a release of a neurotransmitter that releases an action potential.
No, neurotransmitters do not create new action potentials. They transmit signals between neurons by binding to receptors on the receiving neuron, causing a change in the membrane potential of the receiving neuron which may lead to the generation of a new action potential.

When an action potential reaches the end of a neuron, it triggers the release of neurotransmitters into the synapse. These neurotransmitters then bind to receptors on the receiving neuron, causing ion channels to open and allowing ions to flow in, which generates a new action potential in the receiving neuron, thus continuing the signal.
synaptic cleft. This release allows the neurotransmitters to bind to receptors on the postsynaptic neuron, leading to changes in its membrane potential and potentially initiating a new action potential in the receiving neuron.
