What else can I help you with?
What happens when an impulse reaches the end of an axon?
It reaches the synapse and sends neurotransmitters to start a new impulse to the next neuron
When an impulse reaches the end of a neuron it tiggers the releases of?
Neurotransmitters
Why is the chemical synapses be release when a neural impulse reaches the end of an axon?
Chemical synapses release neurotransmitters when a neural impulse reaches the end of an axon to transmit information to the next neuron. This release of neurotransmitters allows for communication between neurons and helps propagate the neural impulse across the synaptic gap to continue the signal.
When the what reaches the end of the axon the neurotransmitter is released?
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
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.
When a nerve impulse reaches the end of the axon the tiny sacs that store the neurotransmitters move to the surface and release the neurotranmistters These tiny sacs that store the neurotransmitters?
are called synaptic vesicles. They contain specific neurotransmitters that are released into the synaptic cleft when the nerve impulse reaches the end of the axon. The neurotransmitters then bind to receptors on the neighboring neuron, continuing the signal transmission.
Once transmission of an impulse is started it always?
Once the electrical, within-neuron signal starts, it will continue to the terminal end of the neuron in an all-or-none fashion, unless influenced by another neuron. For example, an inhibitory (e.g., GABA-ergic) neuron can stop or weaken the electrical signal in the first neuron (e.g., by increasing chloride influx). Once the neuron releases its transmitter, though, the transmitter has been released; however, that chemical signal can be modified either post- or pre-synaptically by action at the receptors.

Is it correct that synaptic clefts prevents an impulse from being transmitted directly from one neuron to another?
Yes, that is correct. The synaptic cleft is a small gap between neurons, and it prevents direct transmission of impulses. When an impulse reaches the end of a neuron, it triggers the release of chemical messengers called neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the adjacent neuron, allowing the impulse to be transmitted indirectly.
How does a signal move through a neuron?
A signal moves through a neuron by traveling along the axon, which is a long, thin extension of the neuron. The signal is transmitted as an electrical impulse called an action potential. When the signal reaches the end of the axon, it triggers the release of neurotransmitters, which then carry the signal to the next neuron.
What reaches the end of the axon when the neurotransmitter is released and diffuses to the muscle membrane to combine with receptors there?
nerve impulse
When a nerve impulse reaches the end of a motor neuron?
When a nerve impulse reaches the end of a motor neuron, it triggers the release of neurotransmitters into the synapse. These neurotransmitters bind to receptors on the muscle fiber, causing a change in membrane potential that eventually results in muscle contraction. This process allows for the transmission of signals from the nervous system to the muscular system, enabling movement and coordination.
Where on a neuron does an impulse start and end?
the impulse starts at the dendrites which is located near the cell body and ends at the synaptic terminals which are at the end of the axon.
