Dendrites are responsible for receiving information from other neurons.

Dendrites are responsible for receiving information from other neurons.

• A. Sending information away from cell body
• B. Receiving information from other neurons
• C. Producing neurotransmitters
• D. Supporting axons with myelin

Answer: (B)

Dendrites are the parts of a neuron that collect messages from other neurons. They have receptors for neurotransmitters released into the synapse, so when a chemical signal arrives, the dendrite adjusts its membrane potential and passes the signal toward the cell body for processing. This receiving role is what makes dendrites the primary way neurons sense and respond to their neural environment. In contrast, the axon is the part that carries information away from the cell body toward other neurons or muscles. Neurotransmitters are produced in the neuron and released at the axon terminals, not on the dendrites. Myelin, produced by glial cells, insulates the axon to speed up signal transmission, not the dendrites. So the statement about dendrites receiving information from other neurons is the accurate description of their function.
