If you have a look at one of the most famous reference book in neuroscience "Principles of neural science" by Kandel (Fifth Edition), on page 22:
There is this figure:
And here is the description of the figure (extracts):
Most neurons in the vertebrate nervous system have several main
features in common. The cell body contains the nucleus, the storehouse
of genetic information, and gives rise to two types of cell processes:
axons and dendrites. Axons are the transmitting element of neurons;
they vary greatly in length, some extending more than 2 m within the
body (...) The action potential, the cell’s conducting signal, is
initiated at the initial segment of the axon and propagates to the
synapse, the site at which signals flow from one neuron to another.
Branches of the axon of the presynaptic neuron transmit signals to the
postsynaptic cell. The branches of a single axon may form synapses
with as many as 1,000 postsynaptic neurons. The apical and basal
dendrites together with the cell body are the input elements of the
neuron, receiving signals from other neurons.
So axons connect with target neuronal cells, either on the dendrites or the soma, to propagate the action potential.
