differentiate between autonomous nervous system, peripheral nervous system, central nervous system with examples.
The nervous system is divided into - central nervous system (CNS) and peripheral nervous system (PNS). The CNS consists of the brain and spinal chord while the PNS consists of the nerves that connect the central nervous system to different parts of the body.
The central nervous system receives information from all parts of the body and also sends information to the muscles. Communication between the CNS and body parts is facilitated by the nerves of PNS.
PNS is further categorized into somatic nervous system and autonomic nervous system(ANS). Somatic nervous system transmit impulses to and from CNS to voluntary organs such as skeletal muscles. Autonomic nervous system transmit impulses to and from CNS to involuntary organs such as heart. ANS is further classified into sympatheic and para sympathetic nervous system.
