Neurons are part of the __________ nervous system.
peripheral |
|
autonomic |
|
central |
|
somatic |
The nervous system consists of the brain and spinal cord (central nervous system) and the peripheral nervous system which is the network of nerve cells (neurons) that collect and distribute signals from the central nervous system throughout the body.

The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (50 - 32)\)
\(C° = {5 \over 9} (18)\)
\(C° = {90 \over 9}\)
\(C° = 10\)
An electrically charged atom is a(n):
proton |
|
electron |
|
neutron |
|
ion |
A compound is a substance containing two or more different chemical elements bound together by a chemical bond. In ionic compounds, one atom borrows an electron from another atom resulting in two ions (electrically charged atoms) of opposite polarities that then become bonded electrostatically.
What is a major difference between the somatic and autonomic nervous systems?
each belongs to a different nervous system |
|
one is inherited, the other is learned |
|
one controls thinking, the other controls feeling |
|
one controls voluntary activity, one controls involuntary activity |
Both are part of the peripheral nervous system. The somatic nervous system sends sensory information to the central nervous system and controls voluntary actions while the autonomic nervous system regulates involuntary activity in the heart, stomach, and intestines.
