Chemicals that cross the synaptic gap and bind to receptors on another neuron are called?
nuerotransmitter
Do antagonists increase the reuptake of neurotransmitters as they cross the synaptic gap that separates neurons?
Antagonists do not typically increase the reuptake of neurotransmitters. Instead, antagonists are substances that block or inhibit the action of neurotransmitters at their receptors, preventing the intended signaling effects. Reuptake refers to the process by which neurotransmitters are reabsorbed by the presynaptic neuron after crossing the synaptic gap, and this process is primarily influenced by transport proteins rather than antagonists.
How does a signal cross the synaptic gap?
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 are The chemicals that bridge the synaptic gap?
Chemicals that bridge the synaptic gap are called neurotransmitters.
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).
Chemicals that cross the synaptic gap and bind to receptors on another neuron are called?
nuerotransmitter
Is a minute gap between a neuron and target cell across which neurotransmitters travel?
No, a minute gap between a neuron and target cell is not enough for neurotransmitters to travel. The space known as the synaptic cleft is actually very small, measuring only about 20-40 nanometers. Neurotransmitters cross this gap by diffusion to bind to specific receptors on the target cell's membrane.
How does a signal cross the synaptic gap?
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.
How does an impulse cross a synaptic gap between two nerve cells?
When an action potential reaches the end of a neuron, it triggers the release of neurotransmitters into the synaptic gap. These neurotransmitters then bind to receptors on the neighboring neuron, causing ion channels to open and allowing the impulse to continue along the second neuron. The neurotransmitters are then either broken down or taken back up by the original neuron to end the signal.
What are The chemicals that bridge the synaptic gap?
Chemicals that bridge the synaptic gap are called neurotransmitters.
What chemical substance carries information across the synaptic gap to the next neuron?

neurotransmitters

Neurotransmitters.
What are the Chemicals that cross the synaptic gap and bind to receptors on another neuron called?
Synapse is a narrow gap containing communicating junction between two neurons where an axon terminal comes near contact with dendrite terminal of next neuron. A narrow fluid filled space, called synaptic cleft, occurs between the two.As the impulse reaches the presynaptic knob, it stimulates release of neurotransmitter into the cleft.
Why are neurotransmitters sometimes referred to as a key?
When an action potential reaches the knoblike terminals at an axon's end, it triggers the release of chemical messengers called neurotransmitters. Within 1/10,000th of a second, the neurotransmitter molecules cross the synaptic gap and bind to receptor sites on the receiving neuron-as precisely as a key fits a lock.
