Is the determination of whether a synapse is excitatory or inhibitory based on what factor?
The determination of whether a synapse is excitatory or inhibitory is based on the type of neurotransmitter released at the synapse. Excitatory synapses release neurotransmitters that promote the firing of the receiving neuron, while inhibitory synapses release neurotransmitters that prevent the firing of the receiving neuron.
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 in the nervous system?
The function of a synapse in the nervous system is to transmit signals between neurons, allowing for communication and coordination of various bodily functions and behaviors.

What is a shunting synapse?
A shunting synapse is a type of synapse that primarily functions to inhibit the activity of a neuron rather than to excite it. When neurotransmitters are released at a shunting synapse, they can cause an increase in the conductance of inhibitory ions, effectively "shunting" or reducing the effect of excitatory inputs. This mechanism plays a crucial role in regulating neuronal signaling and maintaining the balance between excitation and inhibition in neural circuits. Shunting synapses are important for processes such as sensory processing and neuronal stability.
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?
Excitatory and inhibitory signals work together in normal nerve function to maintain balance and regulate the firing of neurons. Excitatory signals stimulate a neuron to fire an action potential, while inhibitory signals prevent or reduce the likelihood of an action potential being generated. This balance is crucial for proper information processing and nerve function in the body.
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 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
Why is pcp more addictive than LSD?
PCP is more addictive than LSD because it works on Dopamine Receptors in the reward pathway. Normally, inhibitory neurotransmitters are active in the synapse. These neurotransmitters inhibit dopamine from being released. When endorphins activate the dopamine receptors, the release of inhibitory neurotransmitters is shut down. Without inhibition, dopamine can be released. PCP mimics endorphins and binds to opiate receptors, turning off dopamine inhibition. Dopamine is allowed to flood the synapse, producing immediate feelings of sedation and well-being. 10 bucks says your in Med Chem with Mr. Choi.
