Q

What are the two most common positions regarding animal experimentation? (2)

A

Q

What does the somatic nervous system do? (3)

A

46
Q

What does the autonomic nervous system do? (3)

A
  • participates in regulation of internal environment
  • afferent nerves carry sensor signals from internal organs to CNS
  • also has efferent nerves that carry motor signals from the CNS to internal organs
47
Q

What are the two types of efferent nerves in the autonomic nervous system? (2)

A
  • sympathetic nerves

48
Q

What do sympathetic nerves do?

A
  • mobilize energy resources in threatening situations (eg. via adrenal gland)
49
Q

What do parasympathetic nerves do?

A
  • act to conserve energy
50
Q

What areas does the spinal cord comprise of? (2)
