What is the primary role of dendrites in a neuron?

Dendrites play a crucial role in the functioning of a neuron by receiving stimuli from other neurons or sensory receptors and conveying this information to the cell body. They are typically branch-like structures that extend from the neuron and can form synaptic connections with the axon terminals of other neurons, allowing for the transmission of electrical signals, known as impulses. By integrating these signals, dendrites are essential for processing information and determining whether the neuron will fire an action potential, thus facilitating communication within the nervous system. This is fundamental in the overall function and responsiveness of neural circuits, making the role of dendrites vital in neurotransmission and the relay of information throughout the body.
