Talk about types of neurons (sensory ones)

Depending on the number, polarity and general arrangement of the extensions in relation to the cell body, there are 4 types of neurons: - Unipolar neurons: they have only one process, the axon which starts from the rounded cell body. This is the typical type in invertebrates. In humans they are present at the embryonic stage of neuroblasts -Pseudo-unipolar neurons: they have a single main process which, near the cell body, is divided into an afferent prolongation (dendrite) and an efferent prolongation (axon). Ex: T-neurons of the spinal ganglia.
