The central nervous system includes the brain and spinal cord, and the peripheral nervous system is the rest.
A human nervous system is much more complex. Unlike a human a jellyfish does not have a central nervous system.

The similarities between the earthworm and human nervous system is that they are carbon based. The difference is that the humans nervous system is skeletal while that of the earthworm is not.
somatic is voluntary autonomic is involuntary.
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
Vertebrates have vertebra.Invertebrates don't.
The somatic nervous system is the voluntary part of the brain and it operates under conscious control. The autonomic nervous system is the part of the brain that is involuntary, and that humans have no control over.
The main difference is that the nervous system controls and coordinates different functions of body and is made up of nervous tissues while respiratory system includes lungs trachea nasal cavities and is concerned with breathing ,its main functional tissues are epithelial and muscular .
Nervous tissue is made up of different cells working together to perform a given function -- in this case, to carry messages from one part of the body to another. Different nervous tissues working together make up nervous system organs, such as nerves, the spinal cord, or the brain. These organs work together in the nervous system, a collection of organs performing a body function. So, in sum, the difference between nervous tissue and the nervous system is one of size and scope: nervous tissue makes up nervous organs, which make up the nervous system.
