Question

question 25 of 30
when you stub your toe, the pain message is carried to your brain by the:
a. central nervous system.
b. autonomic nervous system.
c. parasympathetic nervous system.
d. sympathetic nervous system.

Explanation:

• The central nervous system (CNS) consists of the brain and spinal cord. It is responsible for processing and interpreting sensory information, including pain. When you stub your toe, sensory neurons send pain signals to the spinal cord (part of the CNS), which then relays the information to the brain.
• The autonomic nervous system (ANS) controls involuntary bodily functions like heart rate, digestion. It has two divisions: the sympathetic (fight - or - flight response) and parasympathetic (rest - and - digest response) nervous systems. These are not directly involved in carrying pain messages from the toe to the brain.

Answer:

A. central nervous system
