"Cardiovascular centre The cardiovascular centre is a part of the human brain responsible for the regulation of the rate at which the heart beats through the nervous and endocrine systems. It is found in the medulla oblongata. Normally, the heart beats without nervous control, but in some situations (e.g., exercise, body trauma), the cardiovascular centre is responsible for altering the rate at which the heart beats. It also mediates respiratory sinus arrhythmia. When a change of blood pH is detected by central chemoreceptors or by peripheral chemoreceptors in aortic bodies and in carotid bodies, or a change of blood pressure"
"Phagophobia Phagophobia is a psychogenic dysphagia, a fear of swallowing. It is expressed in various swallowing complaints without any apparent physical reason detectable by physical inspection and laboratory analyses. An obsolete term for this condition is choking phobia, but it was suggested that the latter term is confusing and it is necessary to distinguish the fear of swallowing (i.e., of the propulsion of bolus) from fear of choking. Phagophobia is classified as a specific phobia and according to DSM-IV classification it belongs to the category of ""other phobias"". Phagophobia may lead to (and be confused with) fear of eating, and"

The coronary arteries that run deep within the myocardium are referred to as subendocardial. The coronary arteries are classified as ""end circulation"", since they represent the only source of blood supply to the myocardium; there is very little redundant blood supply, which is why blockage of these vessels can be so critical.

Carotid bodies are considered the primary peripheral chemoreceptor and have been shown to contribute more to a hypoxic response. However, in the chronic absence of the carotid body, the aortic body is able to perform a similar respiratory regulatory role, suggesting that it possesses efficacious mechanisms of signal transduction as well. The differing locations of the two bodies ideally position them to take advantage of different information; the carotid bodies, located on one of the main arteries of"
"Chromophobia Chromophobia (also known as chromatophobia or chrematophobia) is a persistent, irrational fear of, or aversion to, colors and is usually a conditioned response. While actual clinical phobias to color are rare, colors can elicit hormonal responses and psychological reactions. Chromophobia may also refer to an aversion of use of color in products or design. Within cellular biology, ""chromophobic"" cells are a classification of cells that do not attract hematoxylin, and is related to chromatolysis. Names exist that mean fear of specific colors such as ""erythrophobia"" for the fear of red, ""xanthophobia"" for the fear of yellow and ""leukophobia"" for"
"Blood phobia Blood phobia (also AE: hemophobia or BE: haemophobia) is extreme and irrational fear of blood, a type of specific phobia. Severe cases of this fear can cause physical reactions that are uncommon in most other fears, specifically vasovagal syncope (fainting). Similar reactions can also occur with trypanophobia and traumatophobia. For this reason, these phobias are categorized as ""blood-injection-injury phobia"" by the DSM-IV. Some early texts refer to this category as ""blood-injury-illness phobia."" Blood phobia is often caused by direct or vicarious trauma in childhood or adolescence.

The body contains two other, slower acting systems to regulate blood pressure: the heart releases atrial natriuretic peptide when blood pressure is too high, and the kidneys sense and correct low blood pressure with the renin–angiotensin system. Baroreceptors are present in the atria of the heart and vena cavae, but the most sensitive baroreceptors are in the carotid sinuses and aortic arch. While the carotid sinus baroreceptor axons travel within the glossopharyngeal nerve (CN IX), the aortic arch baroreceptor axons travel within the vagus nerve (CN X).

These subjects are sometimes addressed separately, under the names cardiac physiology and circulatory physiology. Although the different aspects of cardiovascular physiology are closely interrelated, the subject is still usually divided into several subtopics. Under most circumstances, the body attempts to maintain a steady mean arterial pressure. When there is a major and immediate decrease (such as that due to hemorrhage or standing up), the body can increase the following: In turn, this can have a significant impact"
"Thoracic diaphragm The thoracic diaphragm, or simply the diaphragm (), is a sheet of internal skeletal muscle in humans and other mammals that extends across the bottom of the thoracic cavity. The diaphragm separates the thoracic cavity, containing the heart and lungs, from the abdominal cavity and performs an important function in respiration: as the diaphragm contracts, the volume of the thoracic cavity increases and air is drawn into the lungs. The term ""diaphragm"" in anatomy can refer to other flat structures such as the urogenital diaphragm or pelvic diaphragm, but ""the diaphragm"" generally refers to the thoracic diaphragm. In"

"Acrophobia Acrophobia is an extreme or irrational fear or phobia of heights, especially when one is not particularly high up. It belongs to a category of specific phobias, called space and motion discomfort, that share both similar causes and options for treatment. Most people experience a degree of natural fear when exposed to heights, known as the fear of falling. On the other hand, those who have little fear of such exposure are said to have a head for heights. A head for heights is advantageous for those hiking or climbing in mountainous terrain and also in certain jobs e.g."

As the center focus of cardiology, the heart has numerous anatomical features (e.g., atria, ventricles, heart valves) and numerous physiological features (e.g., systole, heart sounds, afterload) that have been encyclopedically documented for many centuries. Disorders of the heart lead to heart disease and cardiovascular disease and can lead to a significant number of deaths: cardiovascular disease is the leading cause of death in the United States and caused 24.95% of total deaths in 2008. The primary responsibility of the heart is to pump blood throughout the body. It pumps blood from the body — called the systemic"

Fossa ovalis (heart) The fossa ovalis is a depression in the right atrium of the heart, at the level of the interatrial septum, the wall between right and left atrium. The fossa ovalis is the remnant of a thin fibrous sheet that covered the foramen ovale during fetal development. During fetal development, the foramen ovale allows blood to pass from the right atrium to the left atrium, bypassing the nonfunctional fetal lungs while the fetus obtains its oxygen from the placenta. A flap of tissue called the septum primum acts"

It has four chambers: two ""upper"" chambers, the atria (single:atrium), and two ""lower"" chambers (the ventricles). Anatomically, the atria sit more posterior to the ventricles, but for ease of understanding, are often drawn ""above"" them. The atria are separated from the ventricles beneath by the atrioventricular valves, which open to allow blood into the ventricles and close when ventricular pressure exceeds atrial pressure. Blood is transferred into the ventricles in 2 steps: in the first step, as the ventricle relaxes from"

"Phobophobia Phobophobia is the fear of phobia(s) and, more specifically, of the internal sensations associated with that phobia and anxiety, which binds it closely to other anxiety disorders, especially with generalized anxiety disorders (free floating fears) and panic attacks. It is a condition in which anxiety disorders are maintained in an extended way, which combined with the psychological fear generated by phobophobia of encountering the feared phobia would ultimately lead to the intensifying of the effects of the feared phobia that the patient might have developed, such as agoraphobia, and specially with it, and making them susceptible to having an"

As such, it can be applied to the attitude of a person based on his or her educational background, personal experience and psyche, or to the general position of collective entities like religious groups, institutions or states. Sexophobia in clinical talk has an effect on the way patients speak to their doctors, as it manifests itself in the communication strategies that are employed to speak about private health problems. In that sense, the use of neutral and veiled vocabulary by"

To protect the mother, this lowered immune system is then compensated by a heightened sense of disgust. Because disgust is an emotion with physical responses to undesirable or dirty situations, studies have proven there are cardiovascular and respiratory changes while experiencing the emotion of disgust. As mentioned earlier, women experience disgust more prominently than men. This is reflected in a study about dental phobia. A dental phobia comes from experiencing disgust when thinking about the dentist and all that"

When the brain perceives environmental danger, the amygdala fires a nerve impulse to the hypothalamus to initiate the body's fight-or-flight mode through the sympathetic nervous system. The stress response starts with the hypothalamus stimulating the pituitary gland, which releases the adrenocorticotropic hormone. This signals the release of cortisol, the stress hormone, initiating a multitude of physical effects on the body to aid in survival. The negative feedback loop is then needed to return the body to its resting state by signaling the parasympathetic"

Alternative terms for this condition include ithyphallophobia or medorthophobia. An individual who has the condition is a ""phallophobe"". The term is derived from the word ""phallo"" in Greek meaning penis and at times denoting masculinity, coupled with the suffix phobia. Medomalacuphobia, the fear of losing an erection or acquiring erectile dysfunction, is its antonym. In its broadest sense the term can be used metaphorically, for example in regards to pro-feminists.

As the deranged lymphatic vessels invade the organs and tissues in the chest they put stress on the heart and lungs, interfering with their ability to function normally. Additionally, these lymphatic vessels may leak, allowing fluid to accumulate in the chest, which puts further pressure on the vital organs, thus increasing their inability to function properly. Accumulations of fluid and chyle are named based on their contents and"

It can be triggered by many situations or stimuli, including elevators crowded to capacity, windowless rooms, hotel rooms with closed doors and sealed windows, small cars and even tight-necked clothing. It is typically classified as an anxiety disorder, which often results in panic attacks. The onset of claustrophobia has been attributed to many factors, including a reduction in the size of the amygdala, classical conditioning, or a genetic predisposition to fear small spaces.

Precordium In anatomy, the precordium or praecordium is the portion of the body over the heart and lower chest. Defined anatomically, it is the area of the anterior chest wall over the heart. It is therefore usually on the left side, except in conditions like dextrocardia, where the individual's heart is on the right side. In such a case, the precordium is on the right side as well. The precordium is naturally a cardiac area of dullness. During"
"Cardioplegia Cardioplegia is intentional and temporary cessation of cardiac activity, primarily for cardiac surgery. The word ""cardioplegia"" combines the Greek ""cardio"" meaning the ""heart"", and ""plegia"" ""paralysis"". Technically, this means arresting or stopping the heart so that surgical procedures can be done in a still and bloodless field. Most commonly, however, the word ""cardioplegia"" refers to the solution used to bring about asystole of the heart, or heart paralysis. One of the first physicians to use the term cardioplegia was Dr. Lam in 1957. However his work on the myocardial protection was preceded serendipitously by Sidney Ringer in the late"
