Verified step by step guidance

Understand the structure of a neuron: Neurons are composed of a cell body (soma), dendrites, and an axon. Each part has a specific role in the neuron's function.

Identify the role of dendrites: Dendrites are tree-like extensions at the beginning of a neuron that help increase the surface area available for receiving signals from other neurons.

Clarify the function of dendrites: Dendrites primarily receive and integrate incoming signals from other neurons, which are usually in the form of neurotransmitters released into the synaptic cleft.

Differentiate dendrites from other neuron parts: Unlike axons, which transmit electrical impulses away from the cell body, dendrites do not generate action potentials but rather collect and process incoming information.

Conclude the correct function: Based on the understanding of dendrites' role, they are responsible for receiving and integrating signals, not transmitting impulses away from the cell body or storing neurotransmitters.
