Practice question · Select all that apply
Select every statement that is TRUE about the nervous system.
Hints
- Two options are misconceptions - one misassigns heart control, one reverses CNS and PNS.
- Heart rate is autonomic (not somatic), and everything OUTSIDE the brain and cord is the PNS.
Show the answer
- A. The autonomic nervous system is under conscious voluntary control.
- D. Everything outside the brain and spinal cord belongs to the peripheral system.
- E. Sympathetic and parasympathetic branches act on the same organs in opposite directions.
Why
The balance principle and the two branches' jobs are true. The somatic system runs voluntary muscle (not the involuntary heart), and the CNS is the brain and cord itself - the PNS is what lies outside - so those two are false.
