FUNCTION, ANATOMY, AND WORD PARTS OF
THE NERVOUS SYSTEM
1. State the function of the nervous system and analyze associated
terms.
2. Write the meaning of word parts associated with the nervous system
and use them to build and analyze terms.
3. Distinguish between the structures of the central nervous system and
the peripheral nervous system and define the terms associated with
these structures.

The nervous system
is the control center and communications network.
stimulates movement and senses changes both within and outside
the body.
provides us with thought, learning, and memory.
maintains homeostasis with the help of the hormonal system.
has sensory, integrative, and motor components.

ORGANIZATION OF THE NERVOUS SYSTEM
Central nervous system (CNS) = brain + spinal cord
Peripheral nervous system (PNS) = nerves that connect
the CNS to receptors, glands, and muscles
Types of cells = neurons + neuroglia
