The intracellular stimulus for the secretion of neurotransmitters into the synaptic cleft is an increase in calcium ion levels (Option c).

  • The synaptic cleft refers to the physical space between these two nerve cells (neurons).

  • This space (synaptic cleft) separates a nerve cell (neuron) and a target cell (e.g., another neuron).

  • Neurotransmitters are chemical messengers, which are released to the synaptic cleft in response to changes in calcium levels.

In conclusion, the intracellular stimulus for the secretion of neurotransmitters into the synaptic cleft is an increase in calcium ion levels (Option c).
