Which two parts of the nervous system are responsible for sending and receiving information?

The central nervous system (CNS) and peripheral nervous system (PNS) are essential components of the overall nervous system responsible for processing and transmitting information throughout the body. The CNS, which consists of the brain and spinal cord, serves as the main control center, integrating sensory information and coordinating responses. It processes inputs and generates outputs that affect various bodily functions.

The peripheral nervous system complements the CNS by extending throughout the body and connecting it to the CNS. It is comprised of sensory (afferent) nerves that relay sensory information from the body to the CNS and motor (efferent) nerves that transmit commands from the CNS to the muscles and glands. This integrated system enables the body to respond appropriately to internal and external stimuli, making the interplay between the CNS and PNS crucial for effective communication within the nervous system.

Other options, such as the cognitive and autonomic systems, primarily focus on specific functions rather than the overall mechanisms of sending and receiving information. Similarly, while somatic and sympathetic systems are components of the greater nervous framework, they do not encompass the full extent of information transfer as seen in the central and peripheral systems. The motor and sensory systems refer to specific roles within the nervous system but again do not represent the entire communication capacity
