The space between neuronal celll bodies is the extracellular space, which is filled with extracellular fluid. The space between neurons in contact with one another via a synapse is called a synaptic cleft.
The space between the output of a neuron, the axon, and the input of another neuron, a dendrite, is called a synapse.
While neurons do convey signals between one another, they do not do this by directly touching one another (except for some small molecules which keep them correctly in position, called synaptic adhesion molecules); rather, an output of a neuron, an axon terminal, releases chemicals called neurotransmitters into the gapbetween itself and a dendrite, called the synapse or synaptic cleft or synaptic gap. The neurotransmitters diffuse across the gap, and into receptors on the dendrite, which initiates a neural signal in the dendrites which moves down the dendrites, across the soma (body of the neuron), to the axon hillock(the part of the soma where the axon starts); if enough such signals arrive at about the same time there, either from many other dendrites or from many quick signals from one or more dendrites, then the summation of those signals can trigger an action potential in the axon, thus continuing the neural impulse.
In the form that the question was originally asked, "What is the space between the dendrites and axon in a neuron?", it should be noted that the structure physically between the dendrites (input) part of the neuron and the axon (output) part of the neuron is the body of the neuron, called the soma.
Submicroscopic space between axon and dendrites of two consecutive neurons is called a synapse , it is meant for conduction of nerve impulses .

The dendrite of a neuron usually receives a chemical signal from another neuron, although a cell body (soma), or sometimes even an axon, of another neuron can receive the signal.Synapses which occur between an axon and a dendrite are called axodendritic synapses, while synapses between an axon and a cell body are called axosomatic synapses, and synapses between an axon and an axon are called axoaxonic synapses.
No, not at all. The axon is the transmitting end of a neuron, and a dendrite is the receiving beginning of another neuron.The axon sends its signal "through" a synapse between the axon terminal and a dendrite via chemicals called neurotransmitters that it releases into the synaptic space, which diffuse to and are taken into structures on dendrites called ligand-gated ion pores, which open to allow sodium ions into the dendrite, which change its electrical charge, which initiates the propagation of a corresponding signal along the dendrite and cell body toward the axon hillock, which, if enough signals from dendrites reach it, will then fire and send the nerve signal onward along the axon, as an action potential.

The location of dendrite and axon: If dendrite and axon emerge from same process, the neuron is unipolar. If dendrite and a single axon emerge from opposite ends of the soma, the neuron is bipolar. If the neuron has more than 2 dendrite it is called multipolar.

The tiny space between each axon tip and the next dendrite or muscle is called a synapse. At the synapse, electrical signals from the axon are transmitted to the dendrite or muscle through the release of chemical messengers called neurotransmitters.

Usually from the axon of one nerve to the dendrite of another. The axon sends impulses away from the nerve body, and the dendrite receives impulses from other nerves.

Nerve messages pass from the axon of one nerve into the dendrite of another through a space separating them called the synaptic cleft.
