What do dendrites primarily do in a neuron?

Dendrites play a crucial role in the functioning of neurons by primarily receiving signals from other neurons. These branch-like structures extend from the neuron's cell body and are covered with receptors that respond to neurotransmitters released from the axon terminals of adjacent neurons. When a neurotransmitter binds to a receptor on a dendrite, it generates a small electrical change in the neuron, which can influence whether the neuron will fire an action potential and communicate further information down the line.

Unlike axons that transmit electrical signals away from the neuron, dendrites are specifically designed for signal reception and integration, making them essential for the communication between neurons in neural networks. This function is vital for processing information in the nervous system, allowing the brain and body to respond appropriately to various stimuli. Thus, the primary function of dendrites in a neuron is indeed to receive signals from other neurons.
