Answer: The correct answer for the fill in the blank is conveys; interprets.
Th nervous system is broadly divided into two branches that is Central nervous system ( made up of brain and spinal cord) and peripheral nervous system, which is made up of nerves leaving brain and spinal cord and travelling the rest of the body.
PNS ( peripheral nervous system) receives information ( through sensory division), which is originally gathered by the sensory receptors of the body and send it to the CNS ( central nervous system). The CNS thus interprets the information and gives appropriate response.
Therefore, PNS conveys messages and CNS interprets them.
