What is the name of the fluid-filled space between the pre- and post-synaptic neurons at a chemical synapse?
Options
- ASynaptic cleft
- BSynaptic vesicles
- CSynaptic receptors
- DSynaptic membrane
Correct answer
A. Synaptic cleft
Step-by-step solution
At electrical synapses, the membranes of pre- and post-synaptic neurons are in close proximity, allowing electrical current to flow directly from one neuron into the other across these synapses. Transmission of an impulse across electrical synapses is similar to impulse conduction along a single axon.The membranes of pre- and post-synaptic neurons at a chemical synapse are separated by a fluid-filled space called the synaptic cleft. When an impulse arrives at the axon terminal, it stimulates the movement of the syn
