What is the part of the nervous system that receives information about what is happening within the body and in the outside envi
Alecsey [184]

The peripheral nervous system receives information from the environment and relays commands from the central nervous system to organs and glands.

<h3>What is the peripheral nervous system?</h3>

The nerves that emerge from the brain and spinal cord make up the peripheral nervous system. The CNS and the body components are connected through a network of nerves. The somatic nervous system and the autonomic nervous system are additional divisions of the peripheral nervous system.

The somatic nervous system and the autonomic nervous system are two subsystems of the peripheral nervous system. With the exception of the optic nerve (cranial nerve II) and the retina, the cranial nerves make up the PNS in the somatic nervous system. The second cranial nerve is a tract of the diencephalon and not a real peripheral nerve.  The CNS is where the cranial nerve ganglia were born. The PNS, however, is thought to include the ten remaining cranial nerve axons because they travel outside of the brain.  Smooth muscle and glands are subject to involuntary control by the autonomic nervous system.  The sympathetic and parasympathetic states of the system are made possible by the relationship between the central nervous system and the organs.

Why virus, virions, prions have no place in five kingdom classification​
Ainat [17]

Hey, there!!

There is no place for virus, virions, prions in kungdom classification. The reason is they show both living and non living characters, which don't define them whether they are living beings or non living things.

As in 5 kingdoms, the only living organisms are classified.

  • Kingdom Monera mostly deals with the organism which contains prokaryotic cells.
  • Kingdom Protista deals with the organism which have eukaryotic cells.
  • Kingdom Fungi deals with various fungal organism.
  • Kingdom Plantae deals with various type of plants.
  • Kingdom Animalia deals with various type of animals.

So, you can see that there is non of the kingdoms which deals with the organism which have similar characteristics like viruses, virions and prions.
