검증된 단계별 안내1
Understand the structure of a neuron: Neurons are specialized cells that transmit nerve impulses. They consist of several parts, including dendrites, axon, cell body, and synaptic terminals.
Identify the function of dendrites: Dendrites are tree-like extensions at the beginning of a neuron that help increase the surface area for receiving signals from other neurons. They receive electrical messages from the synapses of other neurons.
Recognize the role of the cell body: The cell body, or soma, is the part of the neuron that contains the nucleus and other organelles. It processes the signals received by the dendrites.
Differentiate between axon and dendrites: The axon is a long, slender projection that conducts electrical impulses away from the cell body, whereas dendrites receive signals and send them to the cell body.
Conclude that dendrites are responsible for receiving signals and sending them to the cell body, making them the correct answer in this context.
