Nervous Systems: Cells and Functions
... • The axon usually carries information away from the cell body. • Axons conduct information to target cells, which can be other neurons, muscle cells, or gland cells. • At its end, the axon divides into many fine nerve endings. At the tip of each nerve ending is a swelling called the axon terminal. ...
