EVERYDAY SCIENCE

Detailed explanation-1: -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.

Detailed explanation-2: -The afferent division of the peripheral nervous system carries impulses to the CNS; the efferent division carries impulses away from the CNS.

Detailed explanation-3: -An axon typically develops side branches called axon collaterals, so that one neuron can send information to several others. These collaterals, just like the roots of a tree, split into smaller extensions called terminal branches. Each of these has a synaptic terminal on the tip.

Detailed explanation-4: -The axon carries impulses away from the cell body. Axons and dendrites are sometimes called nerve fibers.

Detailed explanation-5: -Neurons generally comprise a cell body with one or more extensions. There are two types of extension: dendrites (short extensions with ramifications) and an axon (just one extension of varying length depending on the cells).
