Which neuron morphology is typical for motor neurons?

• A. Unipolar
• B. Sensory
• C. Multipolar
• D. Motor

Answer: (C)

Motor neurons are typically multipolar, meaning they have multiple dendrites along with a single axon. This arrangement lets them integrate input from many other neurons and then transmit a coordinated command to the muscles via the axon. Unipolar (pseudounipolar) neurons are common for sensory pathways, with a single process that splits into peripheral and central branches to carry information toward the CNS. Bipolar neurons are found in specialized senses like vision and balance. The term motor describes what the neuron does, not its shape, so it isn’t a morphology. So, multipolar is the morphology most characteristic of motor neurons.
