If you hit your thumb with a hammer, these wires in your arm -- that, of course, we call nerves -- transmit the information into the junction box in the spinal cord where new wires, new nerves, take the information up to the brain where you become consciously aware that your thumb is now hurt.
Ako se udarite čekićem po palcu, te žice u vašoj ruci -- koje, naravno, zovemo živci -- prenose informaciju do razvodne kutije gdje nove žice, novi živci, prenose informaciju do mozga gdje postajete svjesni da je palac ozlijeđen.
