The heart consists of a right and a left half and is divided into four chambers. The cardiac septum, also called the septum cordis, runs longitudinally between the two halves of the heart. The septum separates the four chambers of the heart into left and right atria, and left and right ventricles. The terms cardiac … Ventricle: Structure, Function & Diseases
Cardiac rhythm is the complete repetitive sequence of heartbeats, including electrical excitation and heart muscle contractions. In people with healthy cardiovascular systems, the atria contract first, pumping blood into the ventricles, which then contract, pushing their blood into the great systemic circulation and into the pulmonary circulation. Normally, the complete heartbeat sequences move in a … Heart Rhythm: Function, Tasks, Role & Diseases
Synonyms Cerebrospinal fluid Medical: Cerebrospinal fluid Definition The cerebrospinal fluid (liquor cerebrospinalis), also known as cerebrospinal fluid, is an endogenous fluid that is largely formed in the chambers (ventricles) of the brain by specialized vascular plexuses, the so-called plexus choroidei. It is formed by filtering the blood. The human body has about 100-150 ml of … Spinal fluid
Composition Normally the CSF/spinal fluid is clear and colorless, so that it resembles water in appearance. It contains very few cells, about 0-3 or 4 per μl. In the newborn, this number can be about twice as high. Mainly leukocytes are found in the cerebrospinal fluid, among them mainly lymphocytes, i.e. immune cells. Less frequently, … Composition | Spinal fluid
Increased cerebral pressure An increase in intracranial pressure may be congenital or acquired. The causes can also be different, either the drainage of the nerve water is disturbed or increased production occurs. Due to the excess of nerve water, there is not enough space in the so-called ventricles of the brain and the brain mass … Increased cerebral pressure | Spinal fluid
While the heart is responsible for maintaining blood circulation with its pumping action, four heart valves ensure that blood always flows in the same direction. The two semilunar valves are each located in the initial region of the large arterial outflow vessels of the two ventricles. The pulmonary valve serves as the outlet valve of … Pocket Flap: Structure, Function & Diseases
Increasing shortness of breath under physical exertion – many sufferers think this is a normal symptom of old age. However, this symptom can be a warning signal for a disease of the heart valves. This thus often remains undetected for years until irrevocable damage to the heart muscle is finally present. Things to know about … Heart Valve Disease: Recognizing Warning Signs!
The LGL syndrome (Lown-Ganong-Levine Syndrome) is one of the cardiac arrhythmias. It is more precisely a preexcitation syndrome. This means that the ventricles are excited a little too early, whereupon they contract and pump blood into the body. This process leads to unpleasant palpitations with a significantly increased pulse rate. However, there are hardly any … LGL Syndrome
Is the LGL syndrome inheritable? There are indications that the LGL syndrome is possibly inherited. However, this is not certain and needs to be further researched. These are the symptoms of an LGL syndrome The LGL-syndrome is characterized by tachycardia. This seizure-like tachycardia is called paroxysmal tachycardia by physicians. The very fast heartbeat has a … Is the LGL syndrome inheritable? | LGL Syndrome
Papillary muscles are small conical, inwardly directed, muscle elevations of the ventricular muscles. They are connected by branching chordae to the edges of the leaflet valves, which act as passive check valves to regulate blood flow from the left atrium to the left and right ventricles. Immediately before the contraction phase of the ventricles, the … Papillary Muscle: Structure, Function & Diseases
A transuctane pacemaker is used externally, outside the body. It is connected to so-called pacing electrodes, which stimulate the heart for a limited time. This pacemaker is used only in emergencies or prophylactically after surgical procedures. What is a transuctoral pacemaker? Transcutaneous pacing of the heart involves sticking electrodes to the patient’s skin that deliver … Transuctane Pacemakers: Applications & Health Benefits
Introduction A hydrocephalus/hydrocephalus refers to a dilatation of the ventricles of the brain, in which the cerebrospinal fluid is located. Depending on the cause, hydrocephalus is classified more closely; either the outflow, production or absorption of the cerebrospinal fluid may be abnormally altered. Indications of hydrocephalus can be complaints such as headaches, nausea, psychological changes, … Therapy of the hydrocephalus
