The Correct Answer is B
Choice A reason:
This is a correct statement. The central nervous system (CNS) is responsible for processing sensory information, generating motor commands, and regulating cognitive and emotional functions.
Choice B reason:
This is an incorrect statement. The peripheral nervous system (PNS) consists of the cranial nerves, spinal nerves, and ganglia that connect the CNS to the rest of the body.
Choice C reason:
This is a correct statement. The autonomic nervous system (ANS) regulates involuntary functions of smooth muscles, cardiac muscles, and glands. It has two branches: the sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS).
Choice D reason:
This is a correct statement. The sympathetic nervous system (SNS) prepares the body for stress or emergency situations by increasing heart rate, blood pressure, respiratory rate, and blood glucose levels. It also dilates the pupils, bronchi, and blood vessels to skeletal muscles.
