The neuron type described in the material is which?

The neuron type described in the material is which?

• A. Bipolar, sensory
• B. Multipolar, motor
• C. Unipolar, motor
• D. Pseudounipolar, autonomic

Answer: (B)

Neurons are categorized by their shape and their job. Motor neurons that control skeletal muscles are typically multipolar, meaning they have many dendrites and a single axon to integrate signals and send commands to muscle fibers. If the material describes a neuron with several dendritic branches around the cell body and one long axon, that fits the classic multipolar motor neuron perfectly. Bipolar neurons, with one dendrite and one axon, are usually found in sensory systems like the retina or olfactory epithelium. Unipolar (pseudounipolar) neurons have a single process that splits into peripheral and central branches and are characteristic of primary sensory neurons in the dorsal root ganglia. Autonomic motor neurons are also motor, but they are typically multipolar as well, not pseudounipolar. So the description best matches multipolar, motor.
