Chemical synapses are the most common type, and they are the ones that most people think of when they hear the term “synapse.” Chemical synapses involve the release of chemical messengers called neurotransmitters, which are released by one neuron and bind to receptors on another neuron, ...
Are endorphins neurotransmitters? How do excitatory neurotransmitters differ from inhibitory neurotransmitters? What class of neurotransmitter is serotonin? Can neurotransmitters be both excitatory and inhibitory? What are chemical synapses in the nervous system and how do they work?
Neurons are connected to each other and tissues so that they can communicate messages; however, they do not physically touch — there is always a gap between cells, called a synapse. Synapses can be electrical or chemical. In other words, the signal that is carried from the first nerve fibe...
involving the release of inflammatory mediators after nerve or tissue damage, demyelination of sensory neuron synapses, and plastic changes in the central nervous system. Different pain mechanisms require different medications. For example, the dopamine receptor antagonist haloperidol ...
Step-by-Step Solution:1. Definition of Synapse: A synapse is defined as the small gap or junction between two neurons, where the transmission of signals occurs. It is crucial for communication in the nervou

Neurons are the fundamental unit of the nervous system that receive and transmit signals to different parts of the body.
Some individuals who are depressed have an abnormally small amount of the neurotransmitter serotonin at certain synapses in the brain. a. One category of antidepressant drugs is called selective serotonin reuptake inhibitors. What action does this drug ...
According to the Hebbian rule, synapses increase their efficiency if the synapse persistently takes part in firing the postsynaptic target neuron. An often-used simplification is those who fire together, wire together, but if two neurons fire exactly at the same time, then one cannot hav...
Neurotransmitters are chemical substances made by the neuron specifically to transmit a message.Neurotransmitters are released from synaptic vesicles in synapses into the synaptic cleft, where they are received by neurotransmitter receptors on the target cell. Neuromodulator A chemical substance or medical ...
