The ________ Lies Between the Presynaptic and Postsynaptic Membranes

Question

The ________ lies between the presynaptic and postsynaptic membranes.
A) synaptic knob
B) cell body
C) synaptic cleft
D) secretory vesicles

Accepted Answer

The synaptic cleft is the narrow space that separates the presynaptic and postsynaptic membranes at a synapse. It is the region across which chemical neurotransmitters diffuse to transmit signals between neurons. The synaptic knob, cell body and secretory vesicles are not located between the presynaptic and postsynaptic membranes.
