The signal between neurons is primarily stopped through the process of neurotransmitter reuptake and enzymatic degradation. After neurotransmitters are released into the synaptic cleft and bind to receptors on the postsynaptic neuron, they are either reabsorbed into the presynaptic neuron by transporters or broken down by enzymes. This cessation of neurotransmitter action prevents continuous stimulation of the postsynaptic neuron, effectively terminating the signal. Additionally, some neurotransmitters may diffuse away from the synapse, further contributing to signal termination.

What is the space junction between two neurons called?
The space junction between two neurons is called a synapse. It is a small gap where the electrical signal in the form of an action potential is converted into a chemical signal in the form of neurotransmitters to allow communication between neurons.
How is contact between neurons accomplished?
Contact between neurons is achieved through structures called synapses. At a synapse, the electrical signal (action potential) in the presynaptic neuron triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the postsynaptic neuron, causing a change in its membrane potential and transmitting the signal.
Does the number of neurons in a chain affect the signal speed?
Yes, the number of neurons in a chain can affect signal speed, but the relationship is not straightforward. While the speed of signal transmission along an individual neuron is primarily determined by factors like myelination and axon diameter, the overall processing time can increase with more neurons due to synaptic delays at each junction. Therefore, a longer chain of neurons can lead to slower overall signal propagation due to these additional processing times, despite individual neurons transmitting signals rapidly.
What are neurons that carry information between sensory neurons and motor neurons?
Interneurons or association neurons.
What are the neurons that serve as links between sensory neurons and motor neurons?
interneuron
Function of neurotransmitter?
To transmit a signal between neurons.
What is the space junction between two neurons called?
The space junction between two neurons is called a synapse. It is a small gap where the electrical signal in the form of an action potential is converted into a chemical signal in the form of neurotransmitters to allow communication between neurons.
What is junction between two neurons?
The junction between two neurons is called a synapse. At the synapse, the electrical signal in the first neuron (presynaptic neuron) is converted into a chemical signal in the form of neurotransmitters, which then travel across the synapse and are received by the second neuron (postsynaptic neuron) to continue the signal transmission.
How does information travel through the small space between neurons in the brain?
Information travels through the small space between neurons in the brain through chemical messengers called neurotransmitters. When an electrical signal reaches the end of one neuron, it triggers the release of neurotransmitters into the synapse, the gap between neurons. These neurotransmitters then bind to receptors on the neighboring neuron, transmitting the signal and allowing communication to occur between the two neurons.
What is the small space between one neuron and the next is called?
A synapse, chemical signals called neurotransmitters cross these gaps, carrying on the signal.
How does information travel across the space between neurons?
Information travels across the space between neurons through chemical messengers called neurotransmitters. When an electrical signal reaches the end of one neuron, it triggers the release of neurotransmitters into the synapse, the gap between neurons. These neurotransmitters then bind to receptors on the neighboring neuron, causing a new electrical signal to be generated and continue the communication process.
How is contact between neurons accomplished?

At a synapse, the electrical signal (action potential) in the presynaptic neuron triggers the release of neurotransmitters into the synaptic cleft.

What are specialized junctions between neurons called?
Specialized junctions between neurons are called synapses. Synapses allow neurons to communicate with each other by transmitting signals in the form of neurotransmitters. There are two main types of synapses: electrical synapses, where ions flow directly between neurons, and chemical synapses, where neurotransmitters are released to relay the signal.
The point of communication between two neurons?
The point of communication between two neurons is called a synapse. At the synapse, the sending neuron releases neurotransmitters into the tiny gap between the two neurons, which then bind to receptors on the receiving neuron, triggering an electrical signal to be sent down the receiving neuron. This process allows for communication and transmission of information between neurons in the brain and nervous system.
How does a neuron send a signal to communicate with other neurons or muscles?
A neuron sends a signal through an electrical impulse that travels down its long, slender body called an axon. When the impulse reaches the end of the axon, it triggers the release of chemical messengers called neurotransmitters. These neurotransmitters then cross the small gap between the neurons or between a neuron and a muscle cell, allowing the signal to be passed on to the next cell.
Do neurons touch each other?
Not exactly; as an impulse moves from one neuron to another it crosses a small space between the neurons called a synapse. The neurons as said to 'not touch' because the cell MEMBRANES of the two neurons do NOT touch, nor merge, nor consequently is there any sharing of cytoplasm between the two neurons. The two neurons ARE, however, HELD TOGETHER at that synapse by small molecules called SYNAPTIC ADHESION MOLECULES, which protrude FROM each neuron into the synaptic cleft or gap and then stick to one another. In this sense, PARTS of neurons do 'touch' PARTS of other neurons, in a MECHANICAL or structural manner, but NOT in an electrical or signal sense. The neural SIGNAL passes through the synaptic cleft or gap via neurotransmitter chemicals which are released by one neuron, diffuse quickly through the gap, and then stimulate a signal in the receiving neuron.
