Understanding Synaptic Transmission

What is the role of the synaptic cleft in neurotransmission?

• It stores neurotransmitters.

• It is the gap where neurotransmitters are released.

• It generates action potentials.

• It degrades neurotransmitters.

Which ion is crucial for the release of neurotransmitters during synaptic transmission?

• Chloride

• Calcium

• Potassium

• Sodium

What is the process called when synaptic vesicles release neurotransmitters into the synaptic cleft?

• Osmosis

• Exocytosis

• Endocytosis

• Diffusion

How do neurotransmitters affect the post synaptic neuron?

• They destroy the neuron.

• They have no effect on the neuron.

• They can either activate or inhibit the neuron.

• They always activate the neuron.

What happens to neurotransmitters after they detach from receptors?

• They remain in the synaptic cleft.

• They are absorbed by the post synaptic neuron.

• They are converted into ions.

• They are degraded or reabsorbed by the preoptic cell.
