If you're asking what the gap between the neurons is called, it is the synapse.
If your asking what the fibrous looking ends of a neuron are called they are the dendrites.
In general, though, when a nerve impulse travels through a nerve fiber, it actually makes repeated hops between the segments of the myelin sheath (the outer coating of the nerve fiber - under a microscope this sheath looks similar to a string of sausage links). As it approaches the end of the fiber the signal is attached to a carrier protein to travel the synaptic gap and into the receptor dendrites of the next neuron in the signal's path.
Neurons transmit signals to one another via synapses. Considering there are gaps at the synapse, how do these neurons stay in place? Same for neuromuscular junctions.

in the micro air sacs
The alveoli in the lungs do not pertain to neurons. Alveoli are small air sacs in the lungs where gas exchange occurs during breathing, while neurons are the cells that transmit electrical signals in the nervous system.

The exchange of oxygen takes place in the alveoli. It is found in our lungs
