Autonomic Nervous System           The Autonomic Nervous System controls internal organs, and is divided into two subsystems, the Sympathetic Nervous System and the Parasympathetic Nervous System. These two control the same organs except that they are the reverse of each other, needed for homeostasis (ensuring a stable internal environment to provide an organism with a certain degree of independence from variations in external environments, like maintaining a constant body temperature).           The motor neurons of the Autonomic Nervous System are not connected to their targets but are instead connected to other motor neurons that link them to their targets.

Self Evaluation The nervous system consists of the brain, the spinal cord, and the network of nerves throughout the rest of the body. It is sometimes called the master system , since it regulates and coordinates every other body system. The nervous system provides a rapid means for the various parts of the body to communicate with each other. It allows us to adjust to the world around us and cope with the challenges of life. It influences how we act or react to stress. The fight or flight response is a good example. This is a hormonally stimulated state to prepare the body for an upcoming threat or challenge. The nervous system is composed of two major parts; the central nervous system (CNS) and the peripheral nervous system (PNS). The central system is the brain and spinal cord, and is where most information is processed. The peripheral system is the network of nerves throughout the rest of the body. The peripheral nervous system allows signals to travel between the central nervous system and the body's sensory receptors and motor effectors, such as the muscles. The Central Nervous System (CNS) consists of the brain and spinal cord.

Subject: Autonomic Nervous System Dysfunction Topic Area: Autonomic Forum: The Neurology and Neurosurgery Forum Question Posted By: jose.cruz on Tuesday, July 09, 2002 Dear Dr, I’m 37 yo man, BMI=22,2, usually healthy. In 2000 I was over weighted(BMI nearly 29)and had a High BP episode of 160/100.Did then, in Sept.2000, an EKG, echocardiogram, renal echo and detailed blood and urine testes (usual plus 24 h, thyroid, renal/suprarenal parameters, etc.) that came all fine. All years I do routine med checkup involving EKG, blood and urine tests that are all fine (All years normal EKG and sinus rhythm under 100 bpm –> 2002 values-> EKG normal/sinus/AFreq=VFreq=96bpm, blood and urine tests were Cholest=164, HDL=71, Triglicerids=48, Glucose=79, ). Now with correct weight my BP is controlled without meds – usually 130-140/80-85, only with very sporadic/spaced measures above (but always bellow 160/95), normally related to anxious states. Sometimes I have high pulse rate in rest (with sweatiness), but some anxious - The max HR was 128 bpm, but usually less in 110’s range that are short time long (max some minutes). When globally calm (physic+emotional+mental) my HR is, usually under 72 and at wake up, sometimes close to low 60’s.

The Autonomic Nervous System When its healthy, you're healthy (Click to see larger image) As part of our treatment program at The Center for Contemporary Medicine, we focus a lot of attention on your Autonomic Nervous System. When this system in your physical body is healthy and functioning at optimum levels, you can heal and prevent disease. Your nervous system is divided into two parts, the voluntary and involuntary systems. You control the voluntary system. For example, when you feel something uncomfortable, you will voluntarily move away from it. The involuntary system, which is the Autonomic Nervous System (ANS), is the one that handles actions over which you normally don't have control, such as heart rate, blood pressure, circulation, and glandular function. Although it is located in your physical body, the ANS is effected by emotions. For example, when you feel fear, that emotion will be translated into a physical response such as the release of hormones (adrenaline), that will increase your heart rate, blood pressure or digestive processes. The ANS is quite complex. To help you understand it, we are going to present it as simply as possible. From the illustration here, you can see how extensive and complex the system is. What is obvious from the illustration is that the ANS runs throughout your body. It originates from the spinal column and is connected to all of your glands and organs.

Syllabus on Geriatric Anesthesiology Mark D. Tasch, M.D. Clinical Associate Professor, Department of Anesthesia Indiana University School of Medicine 1120 South Drive, FH #204 Indianapolis, IN 46202-5115 Mark_Tasch@anesthesia.iupui.edu With advancing age, the autonomic nervous system (ANS), heart and blood vessels become less capable of maintaining hemodynamic stability. While aging is, of course, a heterogeneous process both within and among individuals, some aspects are characteristic of the elderly cohort. Typical developments include a diminution in the tonic influence of the parasympathetic nervous system (PNS), a decline in the responsiveness of b -receptors and a progressive replacement of supple, functional cardiac and vascular tissue by stiff, fibrotic material. Veins are also subject to progressive stiffening with age. The decreased compliance of the capacitance system reduces its ability to "buffer" changes in intravascular volume. Thus, aging can exaggerate the hypotension that results from blood loss, as well as from the peripheral pooling of blood with general or conduction anesthesia.

The Autonomic Nervous System Autonomic versus Somatic NS • Somatic nervous system – consciously perceived sensations – excitation of skeletal muscle – one neuron connects CNS to organ • Autonomic nervous system – unconsciously perceived visceral sensations – involuntary inhibition or excitation of smooth muscle, cardiac muscle or glandular secretion – two neurons needed to connect CNS to organ • preganglionic and postganglionic neurons • Notice that the ANS pathway is a 2 neuron pathway while the Somatic NS only contains one neuron. Basic Anatomy of ANS Preganglionic neuron - cell body in brain or spinal cord - axon is myelinated type B fiber that extends to autonomic ganglion Postganglionic neuron - cell body lies outside the CNS in an autonomic ganglion -axon is unmyelinated type C fiber that terminates in a visceral effector Divisions of the ANS 2 major divisions – parasympathetic – sympathetic Dual innervation – one speeds up organ – one slows down organ – Sympathetic NS increases heart rate – Parasympathetic NS decreases heart rate Sources of Dual Innervation • Sympathetic (thoracolumbar) division – preganglionic  cell bodies in thoracic and first 2 lumbar segments of spinal cord • Parasympathetic (craniosacral) division – preganglionic cell bodies in nuclei of 4 cranial nerves and the sacral spinal cord     Locations of Autonomic Ganglia • Sympathetic Ganglia – trunk (chain) ganglia near vertebral bodies – prevertebral ganglia near large blood vessel in gut

UNIT 8 The Spinal Cord, Spinal Nerves, and the Autonomic Nervous System 15. The Spinal Cord Spinal Cord Description The spinal cord begins below the medulla and ends just above the small of the back at the conus medularis . Recall that the area within the vertebral column beyond the end of the spinal cord is called the cauda equina Meninges Recall also that the spinal cord is protected by the vertebrae and the meninges. The dura mater, arachnoid mater and pia mater of the spinal cord are continuous with those of the brain. Cerebrospinal fluid in the subarachnoid space that lies between the arachnoid and pia mater meningeal layers and in the central canal , a space in the middle of the grey matter of the cord, provides a hydrolic cushion for the spinal column. Internal Composition Cross Section of the Spinal Cord Dorsal and ventral horn cells When the cord is viewed in a cross-section, its grey matter is "H" shaped or, as described by Bhatnagar and Andy,1995, butterfly shaped. It has two ventral and two dorsal horns. The white matter surrounding the cell bodies of the cord is made up of ascending and descending fibers. Motor tracts are found on the ventral and lateral aspects of the cord while sensory tracts run along its dorsal area. Neuronal types Motor neurons These lower motor neurons are located on the ventral aspect of the cord. They are either

CHAPTER 17- Autonomic Nervous System Describe CHAPTER 17- Autonomic Nervous System here (Matt you use the term ganglia in several terms but never define ganglia- can you add that please? Appreciate the humor, personal touch but perhaps a bit more detail as well? MMS Acetylcholine(ACh)- This is a neurotransmitter that is released mostly into the synapses of the peripheral nervous system. It is mainly an excitatory neurotransmittor, for example at junctions with skeletal muscles to make it flex or extend, but can also be inhibitory (slowing of heart rate). In the autonomic nervous system acetylcholine is released in the synapse between the postganglionic neuron and the preganglionic neuron in both the sympathetic and parasympathetic divisions. In addition it is also released in the parasympathetic division's synapse of postganglionic neurons and their effectors. CAK http://www.emory.edu/ANATOMY/AnatomyManual/nervous_system.html Adrenergic neurons - These neurons release norepinephrine. Better hope this is working properly in a fight-or-flight situation.
