Procainamide is a drug belonging to the group of antiarrhythmic drugs. The substance is used primarily in the therapy of cardiac arrhythmias. What is procainamide? Procainamide is a class Ia antiarrhythmic drug. These worsen the excitability of heart cells, leading to prolongation of the action potential. As a result, the heart cells are not as … Procainamide: Effects, Uses & Risks
Delay creams contain locally acting anesthetics such as benzocaine or lidocaine and are used to prolong intercourse in cases of severe premature ejaculation. The cream is used to rub and anesthetize the glans of the penis with the foreskin pushed back about 20 minutes before intercourse, depending on the active ingredient, so that the highly … Delay Cream: Applications & Health Benefits
The biceps tendon reflex is an innate and monosynaptic intrinsic reflex that belongs to the stretch reflexes. Reflectively, the biceps muscle contracts after a blow to the biceps tendon, thereby flexing the forearm at the elbow joint. The biceps tendon reflex may be altered in peripheral and central nerve damage. What is the biceps tendon … Biceps Tendon Reflex: Function, Tasks, Role & Diseases
An action potential is a short-term change in membrane potential. Action potentials typically arise at the axon hillock of a neuron and are the prerequisite for stimulus transmission. What is the action potential? Action potentials typically arise at the axon hillock of a nerve cell and are the prerequisite for stimulus transmissions. The action potential … Action Potential: Function, Tasks, Role & Diseases
Active solute transport is a form of transport of substrates across a biomembrane. Active transport occurs against a concentration or charge gradient and occurs under energy consumption. In mitochondriopathies, this process is impaired. What is active solute transport? Active solute transport is a mode of transport of substrates across a biomembrane. In the human body, … Active Solute Transport: Function, Role & Diseases
Disopyramide is an antiarrhythmic drug. It is therefore used in particular for the drug therapy of cardiac arrhythmias. The active ingredient disopyramide has similarities to the drugs procainamide and quinidine. In most cases, the drug is administered orally. Excretion of the active ingredient from the human body is largely renal. What is disopyramide? The active … Disopyramide: Effects, Uses & Risks
The sense of smell in humans is also called olfactory perception and is divided into three different anatomical structures with the olfactory epithelium, the olfactory filaments and the upstream part of the olfactory brain, which are jointly responsible for the perception as well as processing of odor stimuli. Although the sense of smell in humans … Sense of Smell: Function, Tasks, Role & Diseases
The term visceroception includes all sensory body systems that perceive the state and activity of internal organs, such as the digestive system and cardiopulmonary circulation. The various sensors report their perceptions mostly through afferent pathways of the autonomic nervous system to the brain, which processes the messages further. Most messages proceed unconsciously, so that after … Visceral Perception: Function, Tasks, Role & Diseases
Valproic acid is a non-naturally occurring carboxylic acid. It was first synthesized in 1881 and is used as an antiepileptic. It should not be used in pregnant or breastfeeding women. What is valproic acid? Valproic acid is a non-naturally occurring carboxylic acid. Carboxylic acids are organic compounds that have one or more carboxy groups (-COOH). … Valproic Acid: Effects, Uses & Risks
Positive feedback is a feedback mechanism within the body. It is always referred to as positive feedback when the output variable in a control loop has a reinforcing effect on itself. While negative feedback tends to try to keep the changes in the variables involved as small as possible, positive feedback ensures that the changes … Positive Feedback: Function, Tasks, Role & Diseases
The baroreceptor reflex is initiated by baroreceptors (also called pressoreceptors) in the walls of blood vessels and corresponds to an automatic response of the circulatory center to sudden changes in blood pressure. In case of suddenly lowered blood pressure due to blood loss, the reflex ensures blood supply to vital organs with centralization of the … Baroreceptor Reflex: Function, Tasks, Role & Diseases
The receptor potential is the response of sensory cells to a stimulus and generally corresponds to depolarization. It is also called generator potential and is a direct consequence of the transduction processes by which the receptor converts a stimulus into excitation. In receptor-associated diseases, this process is impaired. What is the receptor potential? The receptor … Receptor Potential: Function, Role & Diseases
