Verified step by step guidance
1
Understand the types of neurons: Neurons can be classified based on their structure into multipolar, bipolar, and unipolar neurons. Unipolar neurons have a single process extending from the cell body.
Identify the function of unipolar neurons: Unipolar neurons are primarily involved in sensory functions, transmitting sensory information from the body to the central nervous system.
Examine the components of the nervous system: The nervous system is divided into the central nervous system (CNS), peripheral nervous system (PNS), autonomic nervous system, and enteric nervous system.
Determine where unipolar neurons are found: Unipolar neurons are predominantly found in the peripheral nervous system, particularly in the sensory ganglia of spinal and cranial nerves.
Conclude the association: Since unipolar neurons are mainly involved in sensory pathways and are located in the peripheral nervous system, the correct answer is the peripheral nervous system.
