The brain, spinal cord, retina, sensory neurons, ganglia, and the nerves
The brain, spinal cord, retina, sensory neurons, ganglia, and the nerves are the organs of the nervous system.
the autonomic nervous system (ANS) includes the peripheal nerves and ganglia on either side of the spinal cord ( note: some textbooks include the ANS as a division pf the peripheal nervous system both ways are correct.)
Brain and spinal cord compose the central nervous system (CNS).All the nerves that innervate everything outside of your CNS is your peripheral nervous system (PNS).
the spinal cord
Yes, the PNS contains ganglia, cranial nerves, and spinal nerves.
Frogs have 9 organ systems: the integumentary, circulatory, skeletal, digestive, muscular, nervous, respiratory, excretory and the reproductive systems.
All vertebrates have ganglia of some sort, but there are many different types of ganglia, from dorsal and spinal to autonomic, basal, sympathetic, and other types. Humans have basal ganglia, which makes up a section of the brain.

The Sympathetic Nervous System and the Parasympathetic Nervous System
CNS is the subsystem of Nervous system which copmrises of brain and spinal cord only while Nervous system comprises brain,spinal cord and ganglia etc
