Branch-like extensions of neurons that detect information from other neurons are called what?

• A. Dendrites
• B. Axons
• C. Soma
• D. Myelin

Answer: (A)

How neurons receive input from other neurons. The branch-like extensions that detect this input are dendrites. They reach out to connections at synapses and have receptors for neurotransmitters released by other neurons. When these chemicals bind to receptors on the dendrites, electrical signals are generated and travel toward the cell body, where they are integrated. The extensive branching of dendrites increases the surface area available for receiving signals from many different neurons, helping the neuron gather information. In contrast, the axon transmits signals away from the neuron to other cells, the soma (cell body) serves as the integration hub, and myelin insulates some axons to speed up signal conduction.
