Which structure contains the nucleus and organelles and integrates signals?

• A. Soma
• B. Dendrites
• C. Axon
• D. Axon Terminal

Answer: (A)

In a neuron, the body part that houses the nucleus and essential organelles and does the work of combining incoming signals is the soma. The soma is like the cell’s control center and energy hub, packed with the nucleus, mitochondria, endoplasmic reticulum, and other organelles needed for metabolism and protein synthesis. Dendrites bring in signals from other neurons and funnel them toward the soma, where these inputs are integrated. If the combined signals reach the threshold, the neuron fires an action potential that travels along the axon. The axon transmits the signal, and the axon terminal releases neurotransmitters to communicate with the next cell. So the structure that contains the nucleus and organelles and performs signal integration is the soma.
