Verified step by step guidance

Understand the classification of neurons based on their structure: Neurons can be classified as multipolar, bipolar, or unipolar based on the number of processes extending from the cell body.

Identify the characteristics of a unipolar neuron: Unipolar neurons have a single process that extends from the cell body, which then branches into two distinct structures. This type of neuron is primarily involved in sensory functions.

Consider the function and location of each neuron type listed in the problem: Motor neurons of the spinal cord are typically multipolar, Purkinje cells in the cerebellum are also multipolar, and interneurons in the brain are usually multipolar as well.

Focus on sensory neurons of the dorsal root ganglia: These neurons are known to be unipolar, as they have a single process that splits into two branches, one connecting to the peripheral sensory receptor and the other entering the central nervous system.

Conclude that sensory neurons of the dorsal root ganglia are classified as unipolar neurons, as they fit the structural and functional criteria for this classification.
