Graded synaptic transmission

WebMost of your synapses are chemical synapses, meaning that information is carried by chemical messengers from one neuron to the next. In the article on synapses, we discussed how synaptic transmission works. Here, we’ll focus on neurotransmitters, the chemical messengers released from neurons at synapses so that they can “talk” to neighboring cells. WebThe axon terminal is adjacent to the dendrite of the post-synaptic—receiving—cell. This spot of close connection between axon and dendrite is the synapse. 4.

WebGraded potentials are small changes in membrane potential that are either excitatory (depolarize the membrane) or inhibitory (hyperpolarize the membrane). Many excitatory graded potentials have to happen at once to depolarize the cell body enough to trigger the action potential. [Attribution and references] Sort by: Top Voted Questions
