MICROANATOMY

Detailed explanation-1: -Dendrites extend out from the cell body and receive messages from other nerve cells. An axon is a long single fiber that transmits messages from the cell body to the dendrites of other neurons or to other body tissues, such as muscles. A protective covering called the myelin sheath, covers most neurons.

Detailed explanation-2: -The dendrites receive messages from other cells or the environment. The cell body contains the nucleus and other important organelles. The axon is a long projection from the cell body that carries the signal in the neuron to the terminal.

Detailed explanation-3: -Dendrites are extensions, or processes, of the cytoplasm that carry impulses to the cell body. An extension or process called an axon carries impulses away from the cell body. Nervous tissue also includes cells that do not transmit impulses, but instead support the activities of the neurons.
