What does an axon release when an impulse reaches the end of it?
Neurotransmitters to the synapse and the neurotransmitters bind with the receptors releasing the second messengers.
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.
A nerve impulse starts at the dendrite then travels to the?
cell body, continues down the axon, and finally reaches the axon terminal. At the axon terminal, the impulse triggers the release of neurotransmitters to communicate with other neurons or muscles.
When an action potential reaches an axon terminal, what happens to the neurotransmitters?
When an action potential reaches an axon terminal, it triggers the release of neurotransmitters into the synaptic cleft.
When an action potential reaches the nerve terminal, what happens to the neurotransmitter release?
When an action potential reaches the nerve terminal, it triggers the release of neurotransmitters into the synapse.
What does an axon release when an impulse reaches the end of it?
Neurotransmitters to the synapse and the neurotransmitters bind with the receptors releasing the second messengers.
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.
How does an impulse cross a synape?
An electrical impulse travels along a nerve until it hits a synapse, where it causes the release of chemicals (neurotransmitters) which migrate across the synapse. At the other side , these neurotransmitters activate receptors which cause an electrical signal to continue along the nerve.
A nerve impulse is carried across a synapse by?
neurotransmitters, which are chemical messengers that transmit signals between neurons. When a nerve impulse reaches the end of a neuron, it triggers the release of neurotransmitters into the synapse. These neurotransmitters then bind to receptors on the neighboring neuron, initiating a new nerve impulse to continue the signal transmission.

When an action potential reaches an axon terminal, what happens to the neurotransmitters?
When an action potential reaches an axon terminal, it triggers the release of neurotransmitters into the synaptic cleft.
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.
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.
What is the route followed by nerve impulses when one neuron communicates with another?
When one neuron communicates with another, the nerve impulse travels down the axon of the presynaptic neuron, reaches the axon terminal, triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the postsynaptic neuron's dendrites, initiating a new nerve impulse in the postsynaptic neuron.
Does the impulse cross the neuromuscular junction when a muscle contracts?
No, the impulse traveling down the axon ends at the axon terminal but causes the axon terminal to release neurotransmitters. The neurotransmitters diffuse across the synaptic cleft causing the sarcolemma of the muscle to initiate its own impulse.
What is the functions of neurotransmitter?
The neurotransmitters are stored in tiny sac-like structures called vesicles at the end of axons. When an impulse, or nerve signal, reaches the end of the axon, the vesicles release a neurotransmitter into the small space between the adjoining cells (synaptic gap). Neurotransmitters diffuse across the synapse and bind to receptors in the receiving cell that are specific for the neurotransmitter.
