Why do neurons have many inputs but one output?

Neurons have many inputs to integrate a wide range of signals from other neurons, allowing them to process complex information and respond appropriately to varying stimuli. This integration occurs through synapses, where multiple neurotransmitter signals can either excite or inhibit the neuron's activity. The single output, typically through the axon, enables the neuron to transmit a unified signal, maintaining clarity and direction in communication within the nervous system. This design helps facilitate efficient processing and coordination of neural information.
