Which part integrates neural information from dendrites and contains the nucleus?

• A. Soma
• B. Axon
• C. Dendrite
• D. Terminal Button

Answer: (A)

The soma, or cell body, is where neural information from the dendrites is integrated and where the nucleus is housed. Dendrites gather signals from other neurons, and the soma sums these inputs to determine if the combined signal reaches the threshold to trigger an action potential. Inside the soma, the nucleus manages the cell’s activities and contains genetic material. Other parts have different roles: dendrites primarily receive information, the axon carries impulses away, and the terminal buttons release neurotransmitters at synapses. So the soma is the key site for both integrating incoming information and housing the nucleus.
