Other unipolar neurons found in invertebrates do not even have distinguishing processes such as dendrites.

The majority of these are unipolar neurons in that they have a single axon leaving the cell body and is sent towards the sensory organ.

Unipolar neurons are common in insects, where the cell body is often located at the periphery of the brain and is electrically inactive.

A unipolar neuron is a type of neuron in which only one protoplasmic process (neurite) extends from the cell body.

Unipolar neurons that begin as bipolar neurons during development are known as pseudounipolar neurons.
