Autonomic Nervous

The classic works of I.P. Pavlov shows strong communication mechanisms between the two most important life-supporting systems of the body - the nervous and the digestive. The role of the autonomic nervous system (ANS) in the occurrence of acute gastroduodenal erosions and ulcers has been proven [1]. The flow of sympathetic impulses causes an excessive release of mediators (catecholamines), which leads to disruption of tissue trophism. An important role in ulceration belongs to the parasympathetic nervous system.

After the maternal abdomen was opened under methoxyflurane anesthesia, fetal rabbits of 27.5 days gestation were given injections through the intact uterine wall of saline, pilocarpine, isoxsuprine, muscarine, phenylephrine, atropine, phenoxybenzamine, or propranolo, alone or in appropriate combinations. Fetal rabbits were delivered by hysterotomy and killed without breathing 2.5 h later. Static pressure-volume curves with air showed improved retention on deflation in fetal rabbits that had injections of pilocarpine, or isoxsuprine, but not of muscarine or phenylephrine. The effect of pilocarpine on the pressure-volume curve was blocked by atropine, phenoxybenzamine, and propranolol, and the effect of isoxsuprine was blocked by propranolol but not phenoxybenzamine. The data suggest that pilocarpine produces secretion of surfactant into lung air spaces by exciting the sympathetic nervous system, a known function of pilocarpine, rather than the parasympathetic nervous system. This may result in stimulation of the same beta-adrenergic receptors affected by isoxsuprine which is also thought to stimulate surfactant secretion.

Coefficient Of Asymmetry

During the information loading in children, the changes of coefficient of functional asymmetry, reflecting strengthening role of left hemisphere in realization of mental activity in the age of 7 to 8 years are revealed. At the same time, shifts of diagnostic parameters of variability of cardiac rhythm depending on age, sex and direction of changes in coefficient of asymmetry are found. Most pronounced changes were found in indexes of activity of sympathetic and parasympathetic nervous system, thus more noticeable change by sympathetic nervous system at loading was observed in girls of the first class, and parasympathetic — in boys of the second class. Dependence of changes of coefficient of functional asymmetry at loading of reference values is established in sympathetic nervous system and Bayevsky index at right-handed persons of 8 years.

Background:: The heart is the central organ of the circulatory system which maintains the flow of blood along with the transport of nutrients to different cells and tissues. A well-functioning cardiac state is a complicated mode of changeability. A healthy heart is not only about oscillation as the rhythmometer is not the same in every circumstance. Heart rate shows variations so that it can be regulated according to psychophysiological conditions to maintain the effect of the internal-external stimulus. Objective:: The main objective of this review is to provide a piece of all-inclusive information about heart rate variability (HRV) and different variables affecting HRV. The direct interconnection among factors and so that HRV can be used in clinical practices. Methods:: This review article contains a detailed survey of literature about HRV available in different online sources such as; Google Scholar, Science Direct, PubMed, and Web of Science, etc. In this review, the authors have focused on the role of the autonomic nervous system in the regulation of HRV and the role of various factors affecting HRV. Results:: The variation in the time between two heartbeats is termed as HRV. It is one of the indicators of many pathological conditions related to cardiovascular health. It provided reliable information about the interaction of the sympathetic and parasympathetic nervous systems. The analysis of the variation of heart rate is a well-known non-invasive technique to identify the functioning of the autonomic nervous system. The autonomic nervous system (ANS) depends on the sympathetic and parasympathetic nervous system for transferring information. The cardio-accelerating center, lungs, and non-striated muscles are innervated by cardiac sympathetic nerves. This division of ANS latches upon the heart accordingly via the cervicothoracic ganglion and vagus nerve. It is found that cardiac normal variability depends upon this stimulation towards the sinoatrial node (pacemaker) which can be evaluated by analyzing the HRV. In human- based studies, it has been found that low level of HRV is one of the main causes of death rate among adults. Hence, HRV helps in identifying the risk of cardiac diseases and the state of ANS. Conclusion:: The heart plays a vital role in the human body and the well-functioning of the cardiac system is the need for a healthy life. The heart contains its nervous system termed as neurocardio system in which ANS plays a key role in which the sympathetic and parasympathetic system interplay to regulate HRV. High HRV is associated with healthy condition while low HRV is associated with pathological conditions. The HRV is influenced by various variables such as; pathological, physiological, psychological, environmental factors, lifestyle factors, and genetic factors, etc.
