The picture you have in your mind of the nervous system probably includes the brain , the nervous tissue contained within the cranium, and the spinal cord , the extension of nervous tissue within the vertebral column.

12.1 Structure and Function of the Nervous System

The autonomic nervous system ANS regulates involuntary functions. Anaesthesia, surgery, and critical illness lead to a varied degree of physiological stress that alters the ANS. The organization of ANS is on the basis of the reflex arc and it has an afferent limb, efferent limb, and a central integrating system. Autonomic neuropathy refers to damage to the autonomic nerves and diabetes mellitus is the most common cause. Autonomic neuropathy involves a number of organs and has serious clinical consequences in the perioperative period and during their management in the critical care unit.

The autonomic nervous system coordinates involuntary control of viscera and other tissues throughout the body, with the exception of skeletal muscle. This branch of the central nervous system, organized into parasympathetic and sympathetic divisions, integrates efferent and afferent fibers that regulate the activities of the majority of organs, glands, and smooth musculature found in the body. The presynaptic cell bodies of neurons composing both categories originate in the gray matter of the spinal column, but are classified by fundamental differences. Anatomically, the origin of the sympathetic thoracolumbar division of the central nervous system lies between the first thoracic T1 and the second or third lumbar section L2 or L3. In contrast, the exiting fibers of the parasympathetic division craniosacral originate from both the medulla oblongata and the sacral portion of the spinal cord S2 to S4. Unable to display preview.

The nervous system is a complex network of nerves and nerve cells neurons that carry signals or messages to and from the brain and spinal cord to different parts of the body. It is made up of the central nervous system and the peripheral nervous system. The central nervous system CNS is made up of the brain and spinal cord. The brain controls most body functions, including awareness, movements, sensations, thoughts, speech and memory. The spinal cord is connected to the brain at the brain stem and is covered by the vertebrae of the spine. Nerves exit the spinal cord to both sides of the body.
