What are dendrites primarily responsible for in a neuron?

Dendrites play a crucial role in the functioning of a neuron by primarily receiving messages from other neurons. They are branched structures that extend from the neuron’s cell body, increasing the surface area available for synaptic connections. When neurotransmitters are released from the axon terminals of neighboring neurons, they bind to receptor sites on the dendrites. This binding generates small electrical signals, or graded potentials, that are then conducted toward the neuron’s cell body.

This process is essential for the integration of information in the nervous system, allowing the neuron to respond to stimuli and communicate with other neurons. By effectively gathering and conveying incoming signals, dendrites facilitate the overall functioning and communication within neural networks.
