What type of membrane potential is generated at the synapse on the postsynaptic membrane?
It can be an excitatory postsynaptic potential (EPSP) or an inhibitory postsynaptic potential (IPSP), depending on the synapse. The EPSP depolarizes the membrane, while the IPSP hyperpolarizes it.
What is the function of a synapse?

What is meant by summation at a synapse and how can the two ways it is accomplished be described?
Summation is the method in which signal transmission between neurons occurs. Summation occurs through excitatory neurotramitters and inhibitory neurotransmitters. Excitatory produces depolarization of the postsynaptic cell. Inhibitory mitigates the effects of an excutatory neurotransmitter. For more information visit the Related Link.
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.
How exitatory and inhibitory interact in normal nerve function?
propagation of impulse pre synaptic to post synaptic
What function does synaptic vesicles containing neurotransmitter?
To send a signal to the next neuron ... across the synapse.
What is the function of sodium deoxycholate in media?
To act as a biological detergent that lyses cells. To act as a biological detergent that lyses cells.
What is the junction point between neurons?
A synapse is the junction or a point of close contact between two neurons.
What is the function of the cell body of the nervous system?
the impulses are brought to the cell body from whre its carried by the axon to the synapse
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.
What is the function of fasciculus gracilis?
The pathway carries epicritic function from the midthoracic trunk through the lower extremities (~ T7 and below) up to the medulla to synapse on the gracile nucleus.
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.
