The correct answer is: It is the part of a neuron that carries information to the cell body.
To answer this question, we need to understand what a dendrite is. A dendrite is a part of a neuron, which is a specialized cell in the nervous system. Neurons have several components, including a cell body, axon, and dendrites.
The role of a dendrite is to receive signals or information from other neurons. It does this by having branches or extensions that form connections, called synapses, with the axons of other neurons. These synapses allow for the transfer of electrical and chemical signals between neurons.
Once the dendrites receive the signals from other neurons, they transmit this information to the cell body of the neuron. The cell body then processes the signals and decides whether to generate and transmit its own signal along the axon, which is another part of the neuron.
In summary, a dendrite is the part of a neuron that carries information to the cell body.
