This article will explain the autonomic nervous system, or ANS, how it works, and the disorders that can affect its functioning. The nervous system is a collection of cells that send and receive electrical and chemical signals throughout the body. The ANS is part of the peripheral nervous system. It is a collection of neurons that influence the activity of many different organs, including the stomach, heart, and lungs. The nervous system regulates the internal environment of the body. It is essential for maintaining homeostasis. Homeostasis refers to the relatively stable and balanced conditions inside the body that are necessary to support life.
The Physiology of the Autonomic Nervous System.
C Grey Matter consists of nonmyelinated interneurons, and white matter is composed of myelinated nerve fibres from the sensory and motor neurons. Association areas are linked to intellectual activities and personality Temporal lobe Sensory areas are associated with vision and hearing; Association areas are linked to memory and interpretation of sensory information Parietal lobe Sensory areas are associated with touch and temperature awareness;. Association areas have been linked to emotions and interpreting speech Occipital lobe Sensory areas are associated with vision;. Association areas interpret visual information Corpus callosum Nerve tract that joins the two cerebral hemispheres Thalamus Coordinates and interprets sensory information and directs it to the cerebrum Hypothalamus Co ordinates many nerve and hormone functions Cerebellum Controls limb movement, balance, and muscle tone Pons Acts as a relay station by sending nerve messages between the cerebellum and the medulla Medulla Oblongata Joins the spinal cord to the cerebellum; one of the most important sites of autonomic nerve control The Autonomic Nervous System The Autonomic Nervous System works together with the endocrine system in adjusting the body to changes in the external or internal environment. All autonomic nerves are motor nerves, Sympathetic- nerve cells system that prepare the body for stress Parasympathetic- returns the body to normal levels after adjustments to stress.
