Where are the sensory nerve cell bodies located?

• A. Neuromuscular junction
• B. Synapses
• C. Dorsal root ganglia
• D. Anterior horn cell

Answer: (C)

Sensory nerve cell bodies are primarily located in the dorsal root ganglia. This location is significant because the dorsal root ganglia contain the cell bodies of sensory neurons, which are responsible for transmitting sensory information from the peripheral nervous system to the central nervous system. The sensory neurons in the dorsal root ganglia have long axons that extend from sensory receptors in the periphery (such as skin, muscles, and organs) and enter the spinal cord through the dorsal roots. This anatomical arrangement is crucial for the proper functioning of the sensory pathways, allowing for the quick and efficient transmission of sensory signals, such as touch, pain, temperature, and proprioception. Understanding this location helps in diagnosing and treating conditions related to sensory nerve injuries or diseases. Other options like the neuromuscular junction involve the ending of motor neurons, synapses are sites of communication between neurons, and the anterior horn contains motor neuron cell bodies, which do not reflect the organization of sensory nerves.
