Introduction:
The most important function of the nervous system is to maintain the body’s temperature, ion balance, and other conditions within optimum levels. The
Answer to Problem 1MCQ
Correct answer:
The peripheral nervous system receives sensory stimuli, whereas the central nervous system integrates sensory information. Hence, the correct answer is option a..
Explanation of Solution
Reason for correct answer:
Option a. is given as “receives sensory stimuli; integrates sensory information.”
The central nervous system consists of two organs: brain and spinal cord, whose function is to integrate sensory information and coordinate the response of the body. The peripheral nervous system transmits information between the central nervous system and the rest of the body.
Reason for incorrect answer:
Option b. is given as, “produces sensory information; produces movements.”
The central nervous system is used for integrating sensory information and for coordinating the body’s responses, while the peripheral nervous system help in processing changes in the external and internal environment. Hence, option b. is incorrect.
Option c. is given as, “integrates sensory information; receives sensory stimuli.”
The central nervous system helps in integrating sensory information, and the peripheral nervous system helps in transmitting the information between the central nervous system and the other parts of the body. Hence, option c. is incorrect.
Option d. is given as, “coordinates voluntary actions; coordinates involuntary actions.”
The central nervous system builds up the peripheral nervous system and conducts information from the brain and spinal cord to the rest of the body. The peripheral nervous system controls both voluntary and involuntary actions. Hence, option d. is incorrect.
Hence, the options b., c., and d. are incorrect.
The sensory information is integrated by the central nervous system; whereas, the sensory stimulus is received by the peripheral nervous system. Thus, the correct option is a..
