What part of a neuron is responsible for receiving information?
- A. axon
- B. terminal bre
- C. dendrite
- D. myelin sheath
Correct Answer: C
Rationale: Dendrites are the part of a neuron responsible for receiving information from other neurons. They are branched structures that extend from the cell body and contain receptors for neurotransmitters. When neurotransmitters bind to these receptors, they generate electrical signals that travel toward the cell body, initiating communication between neurons. Dendrites play a crucial role in integrating incoming signals and determining whether the neuron will fire an action potential.
