Afferent and Efferent are two divisions of which part of the nervous system?

The afferent and efferent divisions are associated with the Peripheral Nervous System (PNS). The afferent division is responsible for carrying sensory information from the body to the central nervous system (CNS), while the efferent division transmits motor commands from the CNS to various effectors, such as muscles and glands. This distinction is crucial in understanding how the nervous system processes and responds to stimuli.

The role of the PNS is to connect the CNS with the limbs and organs, serving as a communication relay between the brain and spinal cord and the rest of the body. This division allows for the integration of sensory data and the execution of motor functions, which highlights the significance of both the afferent and efferent pathways in maintaining bodily functions and responses to the environment.

The other choices pertain to components of the nervous system that do not specifically address the afferent and efferent divisions. The Central Nervous System (CNS) comprises the brain and spinal cord, handling processing and integration but not directly linking to sensory and motor pathways as seen in the PNS.
