Synaptic Cleft
Neuromuscular Junction.
Synapse.
The space between the terminal bouton and dendrite is called the synaptic cleft, or synapse.
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.

Synapse is a narrow gap containing communicating junction between two neurons where an axon terminal comes near contact with dendrite terminal of next neuron. A narrow fluid filled space, called synaptic cleft, occurs between the two.As the impulse reaches the presynaptic knob, it stimulates release of neurotransmitter into the cleft.
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 synapse. It's comprised of 3 parts: an end of the pre-synaptic neuron (called an axon terminal, or axon button), the beginning of the post-synaptic neuron (usually a dendrite, or often a dendritic spine), and the gap in between them (called the synaptic cleft).The synapse is held in place by small molecules called synaptic adhesion molecules, which protrude from each of the axon terminal and the dendrite, and stick together along parts of their lengths, like the two end joints of two fingers, one from each hand, laying against one another and glued together there.
synaptic gap
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.
Nerve messages pass from the axon of one nerve into the dendrite of another through a space separating them called the synaptic cleft.
