Final answer:
Unipolar neurons, found in invertebrate animals, have a single process and stimulate muscles or glands. In humans, resembling unipolar neurons are pseudo-unipolar cells, serving sensory functions with their cell bodies located in ganglia.
Step-by-step explanation:
Unipolar neurons are a distinct class of nerve cells characterized by a single process extending from the cell body.
Unlike in humans, true unipolar neurons are found in invertebrate animals, where they often stimulate muscles or glands.
In the context of humans, what we refer to as unipolar neurons are actually pseudo-unipolar cells.
These specialized sensory neurons have dendrites that receive sensory information which is then transmitted to the central nervous system.
The cell bodies of these pseudo-unipolar neurons are typically located in ganglia.
