The autonomic nervous system is also made up of a third component known as the enteric nervous system, which is confined to the gastrointestinal tract. The autonomic nervous system operates by receiving information from the environment and from other parts of the body. Yet, despite significant noise levels our brain appears to function reliably, presumably because it has evolved under the constraints that are imposed by noise. This system is responsible for sending, receiving, and interpreting information from all parts of the body. The peripheral nervous system (PNS) includes all of the parts of the nervous system outside of the brain and spinal cord. These parts include all of the cranial and spinal nerves, ganglia, and sensory receptors. It is part of the overall nervous system that also includes a complex network of neurons, known as the peripheral nervous system.

The PNS is like the wires that go to individual houses. The nervous system, one of the most complex and important parts of our body, is responsible for responding to external and internal stimuli..

Responses to the integrative decisions are brought about by motor activities (muscular contractions and glandular secretions). Without those “wires,” the signals produced by the CNS could not control the body (and the CNS would not be able to receive … The peripheral nervous system (PNS) is the connection between the central nervous system and the rest of the body. The autonomic nervous system is a complex network of cells that controls the body’s internal state. The autonomic nervous system is a system of efferent (motor) nerves that connect the CNS with internal organs, but unlike the motoneurones that connect directly with skeletal muscles, the pathway between the spinal cord and a visceral organ is interrupted by a synapse within an autonomic ganglion.

The sensory systems keep the central nervous system (the brain and the spinal cord) informed of changes in the external and internal environments.

The nervous system is an organ system containing a network of specialized cells called neurons that coordinate the actions of an animal and transmit signals between different parts of its body. Nervous system, organized group of cells specialized for the conduction of electrochemical stimuli from sensory receptors through a network to the site at which a response occurs. Structure. The presence of noise in nervous systems has profound implications for their computational power174.

Since the nervous system is responsible for controlling most of our vital functions (breathing, heartbeat, hunger, thirst, posture, etc.) The nervous system derives its name from nerves, which are cylindrical bundles of fibers (the axons of neurons), that emanate from the brain and spinal cord, and branch repeatedly to innervate every part of the body. Along with the endocrine system, the nervous system controls the vital functions of the body and maintains homeostasis.

The CNS is like the power plant of the nervous system.

While CNS organs have a protective covering of bone (brain-skull, spinal cord—spinal column), the nerves of the PNS are exposed and more vulnerable to injury. The sensory information is integrated and processed by interneurons in the spinal cord and brain.

It detects and responds to changes inside and outside the body. […] The nervous system is responsible for sending, receiving, and interpreting information from all parts of the body. The nervous system monitors and coordinates internal organ function and responds to changes in the external environment. This system can be divided into two parts: the central nervous system (CNS) and the peripheral nervous system (PNS).

The primary function of the peripheral nervous system is to serve as a pathway of communication between the CNS and the rest of the body.

The nervous system is the part of the body that coordinates voluntary and involuntary actions and transmits signals to and from different parts of its body.
