Verified step by step guidance

Understand the structure of a neuron: Neurons are specialized cells that transmit nerve impulses. They consist of several key parts: dendrites, a cell body (soma), an axon, and often a myelin sheath.

Identify the function of dendrites: Dendrites are tree-like extensions at the beginning of a neuron that help increase the surface area of the cell body. They receive electrical messages from other neurons.

Differentiate between the parts of a neuron: The cell body contains the nucleus and is responsible for maintaining the cell's health. The axon is a long, slender projection that conducts electrical impulses away from the cell body. The myelin sheath is a fatty layer that covers the axon, helping to speed up the transmission of impulses.

Focus on the role of dendrites: Dendrites receive incoming signals from other neurons and conduct these impulses toward the cell body. This is their primary function in the neuron.

Conclude with the correct answer: Based on the functions of each part of the neuron, dendrites are the structures that receive and conduct impulses toward the cell body.
