Which part of the neuron receives signals from other neurons?

• A. Axon
• B. Dendrites
• C. Soma
• D. Synapse

Answer: (B)

Dendrites are specialized structures on neurons that are primarily responsible for receiving signals from other neurons. They are tree-like extensions that increase the surface area available for connections with other neurons, allowing them to detect neurotransmitters released into the synaptic cleft. Once dendrites receive a signal, they convert this information into electrical impulses, which are then transmitted to the soma (cell body) of the neuron. In contrast, the axon is responsible for transmitting the electrical impulses away from the soma to other neurons or muscles. The soma serves to process the signals received and maintain the metabolic functions of the neuron. The synapse is the junction between two neurons where communication occurs, but it is not a part of the neuron that receives signals; rather, it’s the site where signals are transmitted. Therefore, the role of dendrites in signal reception is crucial for neuronal communication and function.
