When an action potential reaches the axon terminal of a neuron, it triggers the release of neurotransmitters into the synaptic gap. These neurotransmitters then bind to receptors on the postsynaptic neuron, causing ion channels to open and allow ions to flow in, generating a new action potential in the receiving neuron.
What else can I help you with?
What is the gap between a neuron and its effector?
The gap between a neuron and its effector is called a synaptic cleft. Neurotransmitters are released from the neuron into this gap and then bind to receptors on the effector cell to transmit the signal.
What chemical is released into the gap to signal the next axon to fire?
The chemical released into the synaptic gap to signal the next axon to fire is called a neurotransmitter. When an action potential reaches the end of an axon, it triggers the release of neurotransmitters from synaptic vesicles into the synaptic cleft. These neurotransmitters then bind to receptors on the postsynaptic neuron, leading to the propagation of the signal if the threshold is met. Common neurotransmitters include acetylcholine, dopamine, and serotonin.
Chemicals that cross the synaptic gap and bind to receptors on another neuron are called?
nuerotransmitter
What are The chemicals that bridge the synaptic gap?
Chemicals that bridge the synaptic gap are called neurotransmitters.
What is the gap where neurotransmitters cross?
Neurotransmitters are formed in the cell body and transported to the axon terminal by Axonic flow of the cytoplasm via axon

What is a synaptic gap?
This is the junction between two neurons. At the one end you have the pre-synaptic membrane - the terminal end of the previous neuron, the pre-synaptic neuron - and on the other side you have the post-synaptic membrane, part of the post-synaptic neuron. Action potentials typically cross the cleft by the use of neurotransmitters. Examples include ACh (Acetyl Choline), often used in the synaptic clefts of parasympathetic neurons.
Chemicals that cross the synaptic gap and bind to receptors on another neuron are called?
nuerotransmitter

Neural transmission across a mammalian synaptic gap is accomplished by?
impulses causing the release of a chemical signal and its diffusion across the synapse.
Where is the synaptic gap?
neourtransmitter
What is the small space separating pre and post-synaptic neurons?
The small space separating pre and post-synaptic neurons is called the synaptic cleft. This cleft allows for the transmission of chemical signals, known as neurotransmitters, from the pre-synaptic neuron to the post-synaptic neuron to occur. The neurotransmitters are released by the pre-synaptic neuron and bind to receptors on the post-synaptic neuron to transmit the signal.
What is synaptic delay?
Synaptic delay is the period of time for neurotransmitter chemicals released from the axon terminus of the sending neuron to cross the synaptic gap by diffusion and attach to matching receptors on the receiving neuron, initiating a reaction (either stimulatory or inhibitory) in that neuron.
How does electrical impulses move through the synapse gap?
Electrical impulses, or action potentials, do not directly move across the synaptic gap; instead, they trigger the release of neurotransmitters from the presynaptic neuron into the synaptic cleft. These neurotransmitters then bind to receptors on the postsynaptic neuron, leading to changes in the postsynaptic membrane potential. This process converts the electrical signal into a chemical signal and back into an electrical signal, allowing communication between neurons.
What do the bubbles of chemical crossing the synapse do?
Chemicals called neurotransmitters move across the synaptic gap by diffusion and carry a neural signal across to the receiving neuron. But the 'bubbles' (vesicles) which contained the neurotransmitter chemicals do NOT themselves cross the synaptic gap, they just release the neurotransmitters into the synaptic gap. (The neurotransmitters move across the synapse, the vesicles do not.)The vesicles release their contents of neurotransmitters into the synaptic gap by a process called exocytosis, in which the neural impulse which reaches the terminal button of the presynaptic neuron causes voltage-gated calcium ion pores to open, allowing an influx of calcium ions, which leads to the fusing of the vesicles to the cell membrane, which amounts to the vesicles 'turning themselves inside out' as the membrane of the vesicle merges with the cell membrane, which expels the neurotransmitters into the synaptic gap.The neurotransmitters flow across the synapse to bind with the postsynaptic neuron, potentially triggering neuron excitation (firing) or inhibition (preventing firing).
