What are dendrites primarily responsible for in a neuron?

Dendrites are primarily responsible for receiving signals from other neurons. They are the branch-like extensions of a neuron that facilitate the communication process between cells in the nervous system. When neurotransmitters released by the axon terminals of other neurons bind to the receptors on the dendrites, they generate electrical signals that can influence the activity of the neuron. This function is crucial for neural communication and the processing of incoming information, allowing the neuron to integrate various signals from multiple sources.

By focusing on the role of dendrites in signal reception, it becomes evident that they are essential for the overall functioning of neural networks, enabling the transmission of information within the brain and the nervous system. Other parts of the neuron, such as the axon, are involved in sending signals, while the cell body is responsible for maintaining the neuron's health and producing neurotransmitters. Protective functions are typically managed by glial cells rather than by dendrites themselves.
