{"role":"assistant","content":"A neuron is a specialized cell that is the fundamental building block of the nervous system. Neurons are responsible for transmitting information throughout the body using electrical and chemical signals. They consist of three main parts:\n\n1. **Cell Body (Soma)**: This contains the nucleus and organelles, which are essential for the cell's metabolic activities and overall function.\n\n2. **Dendrites**: These are tree-like structures that extend from the cell body and receive signals from other neurons or sensory receptors.","refusal":null,"annotations":[]}
