Verified step by step guidance

Understand the structure of a neuron: Neurons are specialized cells in the nervous system that transmit information. They consist of a cell body (soma), dendrites, and an axon.

Identify the role of dendrites: Dendrites are branch-like structures that extend from the cell body. Their primary function is to receive signals from other neurons or sensory receptors.

Clarify the process of signal reception: Dendrites have receptors that bind to neurotransmitters released by other neurons. This binding initiates electrical changes in the dendrite.

Explain signal transmission to the cell body: Once the dendrites receive the signal, they transmit the electrical impulses toward the cell body, where the signals are integrated.

Differentiate from other neuron parts: Unlike axons, which conduct impulses away from the cell body, dendrites are specifically designed to bring information to the neuron, making them crucial for receiving and processing neural information.
