electrical synapses
A synaps. A synaps is where 2 nerve cells meet. In theory and on a microscopical basis, they do not really touch to pass their electric signal. Instead, the arriving nerve potential depolarises some kanals at the end of the first nerve cell, opening them. Thus a bunch of messengers (neurotransmitters) are released from the 1st nerve cell. They float around between the first and second nerve cell (yes, there is a "gap"), and bind on ion kanals on the 2nd nerve cell. The latter kanals open, causing an ion flow, and thus depolarising the cell, causing the electric potential (nerve signal) from the 2nd nerve cell.
The junction between two nerve cells (neurons) is called a synapse.
Between the two cells is a gap, visible using electron microscopy. When an impulse reaches the end of the presynaptic neuron, this cell releases by exocytosis packets of neurotransmitter (e.g. acetylcholine). These cross the gap, and their arrival at the postsynaptic membrane stimulates an impulse in the postsynaptic neuron.
It is called a synapse.

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 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.

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.
synaptic gap
The junction between a motor neruon's axon and the muscle cell membrane is called a neuromuscular junction or a myoneuraljunction?
neuromuscular junction or myoneural junction
The space between two connecting neurons is called a synapse.
Neuromuscular junction.
Synaptic Cleft.
The gap between the axon terminal and muscle cell is called the synaptic cleft. It is defined as the small gap, measured in nanometers, between an axon terminal and any of the cell membranes in the immediate vicinity.

A "synape" is a misspelled synapse.
An axo-axonal synapse is what a connection specifically between one axon and another axon is called. The general term for a connection between neurons is SYNAPSE, and typically is between an axon and a dendrite.
