The human bdy is made f trillins f tiny cells. Each cell is s small that yu need a micrscpe t see them. Yur skin, yur hair, yur eye — all are made up f cells. ___18___ Muscle cells mve yur bdy. Skin cells prtect yur bdy. One special type f cell, neurns (神经元), allw yur brain t send messages t every part f yur bdy.
The center f the nervus system is the brain.

But instead f runners, yu have cells, and instead f a batn, yu have infrmatin. ___20___ It hands its infrmatin t the next cell, which passes the infrmatin t anther cell. In the end, the infrmatin reaches its destinatin and causes a change — maybe a muscle cntracts. The “infrmatin” batn passed frm neurn t neurn is usually a small electrical event called an actin ptential.
A．Just hw fast was the signal mving?
