In several interneuron types, all functions are carried out by dendrites as these neurons are devoid of a canonical axon. This figure shows the synapse of a pre-synaptic neuron (A) and a post-synaptic neuron (B): At the synapse, the pre-synaptic neuron releases neurotransmitters (number 2 in the figure), which are molecules that the post-synaptic neuron detects. Ribosomes are present in dendrites, having tapering ends due to which their diameter goes on decreasing.

The function of the dendrites in general, and of the dendritic spines in particular, is to act as the main contact of the neurotransmitters that arrive from outside. In other words, the dendritic spines act as terminals to which the stimuli arrive from the other neuron that sends neurotransmitters through the synaptic space. You can find an example of a dendritic spine in this micrograph: Once the neurotransmitter binds to the neurotransmitter receptor in the post-synaptic neuron, a signaling cascade starts that enables the information to be processed at the synapse.
