A branch extending from a neuron that receives signals from another neuron through a synapse is called?

• A. Axon
• B. Dendrites
• C. Synapse
• D. Myelin

Answer: (B)

Signals from other neurons arrive at the dendrites. Dendrites are the tree-like, branching extensions of a neuron that host receptors for neurotransmitters at synapses. When chemical messages cross the synapse and bind to these receptors, the resulting electrical signal is generated and travels toward the cell body, potentially triggering an action potential if the signal is strong enough. The other parts have different roles: the axon carries impulses away from the cell body to other cells; the synapse is the junction where communication occurs; myelin insulates and speeds conduction along the axon.
