Final answer:
Multipolar neurons, characterized by one axon and multiple dendrites, are predominantly found in the central nervous system, including the brain and spinal cord, and are exemplified by motor neurons and interneurons.
Step-by-step explanation:
Multipolar neurons are the most common type of neurons and can be found throughout the central nervous system (CNS), which includes the brain and spinal cord. These neurons are characterized by having one axon and multiple dendrites extending from the cell body. Motor neurons and interneurons are common examples of multipolar neurons. Motor neurons are especially large in the spinal cord and are responsible for the initiation of skeletal muscle contraction. For instance, the motor neurons that cause muscle contraction can have very long axons, such as those reaching the muscles in the big toe.
