Synapse
The opening across which one neuron communicates with another neuron is called a synapse. At the synapse, chemical signals called neurotransmitters are released from the presynaptic neuron, which then bind to receptors on the postsynaptic neuron to transmit the signal.
The axon terminals of a neuron are responsible for relaying signals from one neuron to another neuron or to an effector, such as a muscle or gland. When an action potential travels down the axon, it triggers the release of neurotransmitters at the axon terminals, which then stimulate the next neuron or target cell.
The microscopic space that separates the axon terminal of one neuron from the dendrites of another neuron is called the synaptic cleft. Neurotransmitters are released from the axon terminal into the synaptic cleft to communicate with the dendrites of the neighboring neuron.
To "connect" two neurons, (or a neuron and a muscle cell), by providing a space between an axon terminal of one neuron and a dendrite of another neuron (or a muscle cell), so neurotransmitters that are released by an axon terminal can diffuse across that space to reach the dendrite (or muscle cell) and either initiate the possibility of the second neuron to fire or cause a muscle cell to contract.

It is called an Interneuron
