Question

structural classification
the structural classification, which includes all (1 ) system organs, has two subdivisions - the central nervous system and the peripheral nervous system (see figure 7.2)
the central nervous system (cns) consists of the (2 ) and spinal cord, which occupy the dorsal body cavity and act as the integrating and command centers of the nervous system. they interpret incoming (3 ) information and issue instructions based on past experience and current conditions.
the peripheral (pe - ri - fer - al) nervous system (pns) includes all parts of the nervous system outside the cns. it consists mainly of the nerves that extend from the spinal cord and brain. spinal nerves carry impulses to and from the (4 ) cord. cranial (kra ne - al) nerves carry impulses to and from the brain. these nerves serve as communication lines. they link all parts of the body by carrying (5 ) from the sensory receptors to the cns and from the cns to the appropriate glands or muscles.
o 1 spinal 2 impulses 3 nervous 4 brain 5 sensory
o 1 brain 2 sensory 3 spinal 4 impulses 5 nervous
o 1 impulses 2 nervous 3 brain 4 sensory 5 spinal
o 1 nervous 2 brain 3 sensory 4 spinal 5 impulses
o 1 sensory 2 spinal 3 impulses 4 nervous 5 brain

Explanation:

The structural classification pertains to the nervous system organs. The CNS contains the brain and spinal - cord which process sensory information. The PNS has nerves extending from the spinal cord and brain, with spinal nerves connecting to the spinal cord and cranial nerves to the brain, and they carry impulses.

Answer:

1. nervous
2. brain
3. sensory
4. spinal
5. impulses
