What is the primary function of dendrites in a neuron?

Dendrites play a crucial role in the function of neurons by transmitting impulses toward the cell body. They are the branched extensions of a neuron that receive signals from other neurons or sensory receptors. Through their numerous connections, dendrites gather information and relay it to the neuron’s soma, or cell body, where the information is processed. This ability to receive and integrate synaptic signals is essential for the propagation of nerve impulses and overall communication within the nervous system.

While other structures in the neuron also serve important functions, such as the axon, which transmits impulses away from the cell body, or synaptic connections with other neurons, the specific role of dendrites is to ensure that the neuron can effectively receive and process incoming signals. This is vital for coordinating various bodily responses and maintaining homeostasis.
