Functional connection between two neurons is a?
functional connection between two neurons is the transmission of electrical signals from one neuron to another through a synapse. When an electrical impulse reaches the axon terminal of the pre-synaptic neuron, it triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the post-synaptic neuron, allowing the electrical signal to be transmitted and continue the communication between neurons.
What is the name of the region where two neurons are in done contact is known as?
synapse is that junction through which impulse can be transmitted from one neuron to another.
What transfers the nerve impulse from one neuron to another cell at the synapse?
When the sodium ions that entered the cell through the ion channels diffuse into the axon terminal of the neuron, they activate voltage-gated calcium ion channels. As calcium ions flow into the cell, neurotransmitters are released from the cell. These neurotransmitters diffuse across the synapse and activate sodium ion channels in the post-synaptic cell, allowing sodium to flow in and depolarize the cell enough to start another action potential.
What is the tiny space between each axon tip and the next dendrite or muscle called?
The tiny space between each axon tip and the next dendrite or muscle is called a synapse. At the synapse, electrical signals from the axon are transmitted to the dendrite or muscle through the release of chemical messengers called neurotransmitters.
Space through which a nervous impulse is transmitted from one neuron to another?
The synaptic gap, also called the synapse.
Light sensitive worker needed to receive visual images and transmit impules to the brain?
the image passes from neuron to neuron through neurotransmitters until it reaches the brain, where the neurotransmitters are read
What is the small gap between neurons called?
The small microscopic gabs b/w the two neurons are called "Synapse". The conduction of nerve impulse through this synapse is made possible through Neurotransmitters. As the impulse reaches at the Pre-synaptic membrane the small vesicles release these Neurotransmitters which initialize the impulse in post-synaptic membrane.
Where do neurotransmitters act?
They act at the end of a synapse. These are where in the nervous system (relay arc) a relay neurone meets a motor neurone. There is a gap called a synapse between these two neurones and so the only way to transmit the electrical impulse is through neurotransmitters which 'jump' across the gap whilist 'holding' on to the impulse.
The condition that produces inhibition at a synapse is called what?
Neurotransmitters diffuse across the synaptic cleft (a very short distance) and bind to receptor proteins on the postsynaptic membrane. Excitatory neurotransmitters cause sodium ions to move through receptor proteins depolarizing the membrane. Inhibitory neurotransmitters do not depolarize the postsynaptic membrane. Thus, the condition that would produce inhibition at synapse is called HYPERPOLARIZATION.
How does a message. travel across the gap. at a synapse?
it is sent through the neurotransmittersAt the synaptic terminal an electrical impulse will trigger the migration of vesicles containing neurotransmitters toward the presynaptic membrane.
How neurons transmit electro chemical impluses to the brain?
When nerve cells or neurons are stimulated they undergo chemical changes which make little waves of electricity or nerve impulses. These are based mainly on the movement of positively charged sodium and potassium ions through the neurons cell membrane.When the impulses reach a junction-synapse-they trigger the release of chemicals called neurotransmitters. These then cross the synapse and stimulate the receiving neuron to fire impules of their own. Dendrites collect nerve impulses and Axons convey impulses away from cell.
How does heroin affect the Synapse?
In a regular nerve synapse, not exposed to any antigens and in a healthy body, inhibitory, or preventative, neurotransmitters are released constantly to prevent the release of dopamine (<----neurotransmitters), a natural painkiller(or mood-lifter). When the body is severely damaged or injured, natural opiates are released and travel to the inhibitory neurotransmitters. When the opiates arrive at the inhibitory neurotransmitters, they enter the opiate receptors. Once this occurs, the dopamine neurotransmitters can be released and travel to dopamine receptors, to travel through neurons to the rest of the body. Once heroin is brought into the body, people feel a short, but immediate, high. The heroin simulates natural opiates. The heroin travels through the body to the inhibitory neurotransmitters and to the opiate receptors. Once the body has received the heroin, the inhibitory neurotransmitters are no longer released, at least until the heroin wears off. The dopamine is now released and the drug user feels a high from the effects of the dopamine. There is a great source that explains not only the effects of heroin on the synapse, but several other drugs too.
What role do dendrites play in transmission at chemical synapses?
Dendrites are the beginning of action potentials as they are formed and then propagate through a neuron. At the synapse, the dendrites receive the incoming signal from neurotransmitters released at the terminal of the previous neuron.

What is the space between two adjacent nerve cells?
its known as the synapse. Through the synapse is where impulses travel from brain cell to brain cell.
What can cause synapse to not function correctly?
An abnormally thin dendritic spine can yield poor neural impulse conduction; and drugs like LSD which mimic neurotransmitters may "clog" receptors & cause continued activation, I think. I suspect there could also be problems with the PRODUCTION of neurotransmitters or with the conveyance of vesicles containing NT to the synapse. Synapses are spaces or junctions between two neurons. The principle of synapse works on mechanism of neuro-transmitters and neuro-inhibitors. When a nerve impulse reaches the end of one neuron to travel to the next one, at that moment acetylcholine is produced in the synapse. Acetyl choline being a neurotransmitter helps to transmit the nerve impulse. Right after the nerve impulse has passed through the synapse, a neuroinhibitor such as cholinesterase si produced to stop the action of acetylcholine. At a particular synapse, these two chemicals are produced at a very high rate. This is how a nerve impulse works. But suppose if the production of these two chemicals is affected, the synapse will not function properly.
