The site in a neuron where information from thousands of other neurons is collected and integrated is the

• A. Cell body (soma)
• B. Axon
• C. Myelin sheath
• D. Terminal buttons

Answer: (A)

Signals arriving from thousands of inputs are collected and summed mainly in the cell body. The dendrites pull in information from many neurons, and the soma acts as the integration center, combining excitatory and inhibitory signals. When the total reaches the threshold at the axon hillock, an action potential is triggered and travels along the axon. So, the cell body is the key site where widespread synaptic input is gathered and decisions about firing are made. The other parts have different roles: the axon transmits the signal away, the myelin sheath speeds conduction, and the terminal buttons release neurotransmitters into synapses.
