{"role":"assistant","content":"A neuron is a fundamental building block of the nervous system, responsible for transmitting and processing information throughout the body. Neurons are specialized cells that communicate via electrical and chemical signals. They consist of three main parts:\n\n1. **Cell Body (Soma)**: The central part of the neuron that contains the nucleus and organelles. It integrates incoming signals and generates outgoing signals.\n\n2. **Dendrites**: Branch-like extensions from the cell body that receive signals from other neurons and sensory receptors.","refusal":null,"annotations":[]}
