What is the space between dendrite and axon within a neuron called?

Explanation:
The space is called the synaptic cleft. At chemical synapses, the sending neuron releases neurotransmitters into this tiny gap, which then diffuse across the cleft and bind to receptors on the receiving neuron's membrane to propagate the signal. The nucleus and cytoplasm are parts of the cell’s interior, while the axon hillock is the region where an action potential often starts. Note that the cleft is the gap between neurons at a synapse, not a space inside a single neuron.
