Question

Quizplus · Accepted Answer

The synaptic cleft is the space between the presynaptic and postsynaptic cells.

Answer: A
 The presynaptic cell is the neuron that sends the signal across the synapse and releases the neurotransmitter.

Answer: B
 A neurotransmitter is a chemical released by the presynaptic cell that binds to receptors on the postsynaptic cell and transmits the signal.

Answer: C
 The postsynaptic cell is the neuron that receives the signal from the presynaptic cell.

Answer: D
 The synaptic knob, also known as the axon terminal, is the end of the presynaptic neuron that contains vesicles filled with neurotransmitters.

Answer: F
 A chemical synapse involves the release of neurotransmitters from the presynaptic cell and the binding of these neurotransmitters to receptors on the postsynaptic cell.

Answer: E
 An electrical synapse is a type of synapse where ions can pass directly between the presynaptic and postsynaptic cells through gap junctions.
