Autonomic innervation of the heart
 
04:09
This video tutorial briefly covers the sympathetic and parasympathetic role on heart innervation. It focuses on the following: - Sympathetic neurotransmitters (epinephrine and nor-epinephrine) and receptors (adrenergic). - Parasympathetic neurotransmitters (acetylcholine) and receptors (muscarinic).

Baroreflex is a rapid negative feedback loop in which an elevated blood pressure causes heart rate and blood pressure to decrease. Reversely, a decrease in blood pressure leads to an increased heart rate, returning blood pressure to normal levels. The reflex starts with specialized neurons called baroreceptors. These are stretch receptors located in the wall of the aortic arch and carotid sinus. Increased blood pressure stretches the wall of the aorta and carotid arteries causing baroreceptors to fire action potentials at a higher than normal rate. These increased activities are sent via the vagus and glossopharyngeal nerves to the nucleus of the tractus solitarius – the NTS - in the brainstem. In response to increased baroreceptor impulses, the NTS activates the parasympathetic system – the PSNS - and inhibits the sympathetic system – the SNS. As the PSNS and SNS have opposing effects on blood pressures, PSNS activation and SNS inhibition work together in the same direction to maximize blood pressure reduction. Parasympathetic stimulation decreases heart rate by releasing acetylcholine which acts on the pacemaker cells of the SA node. Inhibition of the sympathetic division decreases heart rate, stroke volume and at the same time causes vasodilation of blood vessels. Together, these events rapidly bring DOWN blood pressure levels back to normal. When a person has a sudden drop in blood pressure, for example when standing up, the decreased blood pressure is sensed by baroreceptors as a decrease in tension. Baroreceptors fire at a lower than normal rate and the information is again transmitted to the NTS. The NTS reacts by inhibiting parasympathetic and activating sympathetic activities. The sympathetic system releases norepinephrine which acts on the SA node to increase heart rate; on cardiac myocytes to increase stroke volume and on smooth muscle cells of blood vessels to cause vasoconstriction. Together, these events rapidly bring UP blood pressure levels back to normal. Baroreflex is a short-term response to sudden changes of blood pressure resulted from everyday activities and emotional states. If hypertension or hypotension persists for a long period of time, the baroreceptors will reset to the “new normal” levels. In hypertensive patients for example, baroreflex mechanism is adjusted to a higher “normal” pressure and therefore MAINTAINS hypertension rather than suppresses it.

This video and other related images/videos (in HD) are available for instant download licensing here : https://www.alilamedicalmedia.com/-/galleries/images-videos-by-medical-specialties/neurology ©Alila Medical Media.

Voice by: Ashley Fleming All images/videos by Alila Medical Media are for information purposes ONLY and are NOT intended to replace professional medical advice, diagnosis or treatment. Always seek the advice of a qualified healthcare provider with any questions you may have regarding a medical condition. The autonomic nervous system, or ANS, is the part of the nervous system that regulates activities of internal organs. The ANS is largely AUTONOMOUS, acting independently of the body’s consciousness and voluntary control. It has two main divisions: sympathetic, SNS, and parasympathetic, PSNS. In situations that require alertness and energy, such as facing danger or doing physical activities, the ANS activates its sympathetic division to mobilize the body for action. This division INcreases cardiac output, accelerates respiratory rate, releases stored energy, and dilates pupils. At the same time, it also inhibits body processes that are less important in emergencies, such as digestion and urination. On the other hand, during ordinary situations, the parasympathetic division conserves and restores. It slows heartbeats, decreases respiratory rate, stimulates digestion, removes waste and stores energy. The sympathetic division is therefore known as the “fight or flight” response, while the parasympathetic division is associated with the “rest and digest” state. Despite having opposite effects on the same organ, the SNS and PSNS are NOT mutually exclusive. In most organs, both systems are simultaneously active, producing a background rate of activity called the “autonomic tone” - a balance between sympathetic and parasympathetic inputs. This balance SHIFTS, one way or the other, in response to the body’s changing needs. Some organs, however, receive inputs from ONLY ONE system. For example, the smooth muscles of blood vessels only receive sympathetic fibers, which keep them partially constricted and thus maintaining normal blood pressure. An increase in sympathetic firing rate causes further constriction and INcreases blood pressure, while a DEcrease in firing rate dilates blood vessels, lowering blood pressure. The autonomic nerve pathways, from the control centers in the central nervous system to the target organs, are composed of 2 neurons, which meet and synapse in an autonomic ganglion. Accordingly, these neurons are called PREganglionic and POSTganglionic. In the SNS, the preganglionic neurons arise from the thoracic and lumbar regions of the spinal cord; their fibers exit by way of spinal nerves to the nearby sympathetic chain of ganglia. Once in the chain, preganglionic fibers may follow any of 3 routes: some fibers synapse immediately with postganglionic neurons; some travel up or down the chain before synapsing; some pass through the chain without synapsing - this third group continues as splanchnic nerves to nearby collateral ganglia for synapsing instead. From the ganglia, LONG POSTganglionic fibers run all the way to target organs. The SNS has a high degree of neuronal DIVERGENCE: one preganglionic fiber can synapse with up to 20 postganglionic neurons. Thus, effects of the SNS tend to be WIDESPREAD. In the PSNS, the preganglionic neurons arise from the brainstem and sacral region of the spinal cord. Preganglionic fibers exit the brainstem via several cranial nerves and exit the spinal cord via spinal nerves before forming the pelvic splanchnic nerves. Parasympathetic ganglia are located near or within target organs, so postganglionic fibers are relatively short. The degree of neuronal divergence in the PSNS is much lower than that of the SNS. Thus, the PSNS produces more SPECIFIC, LOCALIZED responses compared to the SNS.

The autonomic nervous system (ANS), formerly the vegetative nervous system, is a division of the peripheral nervous system that supplies smooth muscle and glands, and thus influences the function of internal organs. The autonomic nervous system is a control system that acts largely unconsciously and regulates bodily functions such as the heart rate, digestion, respiratory rate, pupillary response, urination, and sexual arousal. This system is the primary mechanism in control of the fight-or-flight response.

Successful Sleep Through Calming Autonomic Systems
 
02:51
Sleep is controlled by autonomic factors that keep your heart pumping and your breathing going. Breathing is one of the bridges of the autonomic nervous system that actually allows the body to relax when it wants to and to take in deep breath when it needs to. https://www.drlam.com/blog/relaxing-breathing-could-be-your-answer-to-sleep-disturbances/25441/ This is Dr. Lam, founder of drlam.com. And today’s topic is sleep series autonomic factors. Now sleep is a very interesting phenomena because when you’re sleeping you obviously are not conscious. But yet the body is moving along and doing everything it should be. This is controlled by the autonomic factors. The autonomic nervous system is in full control helping your body not only to keep the heart going but also help your breathing going. Now breathing is very interesting because, you know, it’s one of the only autonomic functions that you can actually control when you want it and not allow the body to maintain its own control. So let me explain. Now let’s say you have a heart, and you are beating. You cannot just tell the heart to stop. It’s going to beat whether you like it or not, it’s just a matter of whether faster or slower when the body decides it needs to be. Breathing can be stopped at will. You can say, body, stop the breathing for the next 20 seconds and start breathing again. You are in total control. So breathing is one of the bridges of the autonomic nervous system that actually allows the body to relax when it wants to and to take in deep breath when it needs to. Now how does this play into the sleep? During the sleep process the relaxing part of the breathing as well as the working part of the breathing are both functional. And they have to be in unison. And when that is not working well then you can have sleep apnea, you can have frequent awakening, you can have wild dreams, you can have nightmares, and you can even have choking episodes. So learning how to breathe is a way to bridge and modulate the autonomic nervous system. And when the autonomic system is better functioning, your sleep is going to improve.

Predicting the body: autonomic regulation and emotion
 
49:09
QAAFI Science Seminar Presented by Dr Marcus Gray NHMRC Australian Clinical Research Fellow Centre for Advanced Imaging The University of Queensland http://www.cai.uq.edu.au/gray ABSTRACT The mind is embodied, and much of mental activity, including cognitive, emotional and executive processing, interacts with the control of internal physiological state. Influential peripheral theories of emotion argued that emotional feelings arise primarily from internal bodily sensations. Linking both these early feed-forward models of emotion and 20th century refinements, recent brain imaging studies implicate activity in regions such as the insula cortex with internal maps of bodily state and associated emotional feelings. While internal state may drive emotions, beliefs and cognitions about the causes of physiological changes also play a critical role. In a series of studies, we have examined the central representation of cardiac afferent signals, and their influence on fear conditioning and extinction, attention, and the representation of nociceptive stimuli. These results extend understanding of the scope of cardiac afferent influences, and further demonstrate subtle interactions between physiological regulation and cognitive - emotional processing. Currently, work is under way to frame physiological regulation, and its assimilation within cognitive and affective processes, within a predictive coding model of interoceptive inference. This extends the Bayesian Brain hypothesis in which perception, action and cognition are the expression of the brains indirect predictions about the source of sensory data. Neuro-imaging findings demonstrate emotion-specific patterning of autonomic responses, and a discrete set of brain regions implicated in translating internal bodily responses into emotional experience and motivational behaviour.
