Question

question 26 of 30
dan was running, and he tripped and hurt his knee. the pain signals were carried to his brain by the:

a. sympathetic nervous system.

b. central nervous system.

c. lobes of the brain.

d. endocrine system.

Explanation:

The sympathetic nervous system is part of the autonomic nervous system and is involved in transmitting sensory (including pain) signals. The central nervous system (brain and spinal cord) processes signals but the question is about carrying pain signals to the brain, and the sympathetic nervous system (a division of the peripheral nervous system's autonomic part) helps in transmitting such sensory signals. The lobes of the brain process signals, not carry them, and the endocrine system uses hormones, not for pain signal transmission. So the correct answer is A.

Answer:

A. sympathetic nervous system.
