What is the role of dendrites in the nervous system?

Dendrites play a critical role in the function of neurons by carrying impulses toward the nerve cells. They are specialized extensions of the neuron that receive signals from other neurons or sensory receptors. When these signals are received, they are converted into electrical impulses that are then transmitted to the cell body of the neuron for further processing.

Dendrites increase the surface area of the neuron, allowing it to receive and integrate a greater number of signals. This is essential for communication within the nervous system, as neurons need to relay information efficiently and effectively. The more inputs a neuron can gather via its dendrites, the better it can respond to stimuli and communicate with other neurons. This function is crucial for the overall operation of the nervous system, including reflexes, muscle movement, and sensory perception.
