False. Nodes of Ranvier are sections along a mylenated axon that are not mylenated. Instead they contain numerous voltage gated Na and K channels. These channels help transmit the chemical depolarization along the axon until it reaches the synaptic node. Neurotransmitters are stored in synaptic vessicles in the synpatic node.

How do action potentials move from one neuron to another?
The action potential stimulates the axon terminal to release its neurotransmitters. The neurotransmitters attach themselves to the dendrote of the next neuron, so that it will open its NA+ channels.
What is a active zone?
An active zone is a specialized region within a neuron where neurotransmitters are released to communicate with other neurons at a synapse. It is where the presynaptic neuron releases neurotransmitters into the synaptic cleft, which then bind to receptors on the postsynaptic neuron to facilitate communication between the two cells.
What are neuronal endings?
Neuronal endings, also known as axonal terminals, are the tips of axons that make connections with other neurons, muscles, or glands. These structures play a critical role in transmitting information between neurons by releasing neurotransmitters across the synapse. Neurotransmitters allow for communication and signal transmission within the nervous system.
How does transmission occur in the Central Nervous System?
Transmission of data occurs within our Central nervous system by means of Neurons.there are mainly three types of neuronsSensory neuronsmotor neuronsinter neurons
What is the correct route a message takes within a neuron?
Well, isn't that just a happy little question! When a message travels within a neuron, it starts at the dendrites, moves through the cell body, and then down the axon. Finally, it reaches the axon terminals where it can pass on to the next neuron. Just like painting a beautiful landscape, each step is important in creating a masterpiece of communication in our brains.
Where are neurotransmitters stored in the neuron?
Neurotransmitters are stored in small sacs called vesicles within the axon terminals of a neuron.
Where are nuerotransmitters stored?
Neurotransmitters are stored in tiny sacs called synaptic vesicles within the axon terminals of neurons. When an action potential travels down the neuron, these vesicles release neurotransmitters into the synapse, where they can then bind to receptors on the adjacent neuron.
Neurotransmitters are stored in synaptic vesicles called the?
Neurotransmitters are stored in synaptic vesicles called the presynaptic terminal. These vesicles are located at the end of the axon terminal of a neuron and release neurotransmitters into the synapse to facilitate communication with other neurons.
What part of a neuron contains neurotransmitters?
Neurotransmitters are used to send messages from cell to cell, usually neuron to neuron. Neurotransmitters are released from the pre-synapse, which is at the axon terminus. These neurotransmitters are picked up by the post-synapse on the receiving cell. These post-synapses are located on structures called dendrites or on the cell body.
Where are neurotransmitters stored in nerves?
Neurotransmitters are stored in small sacs called vesicles within the nerve cells, specifically in the axon terminals.
How do action potentials move from one neuron to another?
The action potential stimulates the axon terminal to release its neurotransmitters. The neurotransmitters attach themselves to the dendrote of the next neuron, so that it will open its NA+ channels.
How do neurotransmitters travel within the brain and nervous system?
Neurotransmitters travel within the brain and nervous system by crossing the synapse, a small gap between neurons. They are released from the axon terminal of one neuron, travel across the synapse, and bind to receptors on the dendrites of the next neuron, transmitting signals between neurons.
Communication within a neuron is electrical while communication between neurons is chemical.?
Yes, that's correct. Within a neuron, communication occurs through electrical signals that travel along the neuron's axon. When these signals reach the synapse (junction between neurons), they trigger the release of chemical neurotransmitters that carry the signal to the next neuron.
What is a active zone?
An active zone is a specialized region within a neuron where neurotransmitters are released to communicate with other neurons at a synapse. It is where the presynaptic neuron releases neurotransmitters into the synaptic cleft, which then bind to receptors on the postsynaptic neuron to facilitate communication between the two cells.
How is the communication between neurons an electrochemical event?
Because the charge travels from the dendrites to the axon to the head of the neuron, now remember neurons do not touch (synapse) so the the charge must now get to the dendrites of the next neuron from the head of the first, so the head releases chemicals called Nero transmitters that carry the impulse to the next neuron. thus Electro-Chemical
What are neuronal endings?
Neuronal endings, also known as axonal terminals, are the tips of axons that make connections with other neurons, muscles, or glands. These structures play a critical role in transmitting information between neurons by releasing neurotransmitters across the synapse. Neurotransmitters allow for communication and signal transmission within the nervous system.
What happens when a substance gets into a neuron?
When a substance enters a neuron, it can bind to receptor sites on the neuron's membrane, triggering a cascade of events within the neuron. This can lead to changes in the neuron's electrical activity, release of neurotransmitters, or alterations in gene expression, ultimately affecting the neuron's function.
