What are pseudounipolar, bipolar and multipolar neurons?

In pseudounipolar neuron, the cell body gives rise to a single process, which bifurcates immediately into two axons. The primary sensory neurons (neurons conveying impulses from the sensory receptors to the spinal cord) are pseudounipolar.

In bipolar neurons, a process projects from each end of the cell body. Cells of this type are found in the vestibular and cochlear ganglia and in the nasal olfactory epithelium. A multipolar neuron gives rise to numerous dendrites and usually a single axon. Most neurons in the brain are multipolar.
