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 several parts, including dendrites, axons, and the soma (cell body).

Identify the function of dendrites: Dendrites are branched extensions of the neuron. Their primary function is to receive signals from other neurons and transmit these signals to the soma.

Differentiate between dendrites and other neuron parts: Axons are long, slender projections that transmit signals away from the soma to other neurons, muscles, or glands. The soma is the cell body that contains the nucleus and is responsible for maintaining the cell's health.

Clarify the role of synapses: Synapses are the junctions where neurons communicate with each other. They are not part of the neuron structure itself but are crucial for signal transmission between neurons.

Conclude with the correct identification: Based on the functions and structures described, the branched extensions of a neuron that receive signals are called dendrites.
