The term excitation conduction refers to the transmission of excitation in nerve or muscle cells. Excitation conduction is also often referred to as conduction of excitation, but from a medical point of view, this term is not entirely correct. What is excitation conduction? The term excitation conduction refers to the transmission of excitation in nerve … Excitation Conduction: Function, Tasks, Role & Diseases
The threshold potential describes a specific charge difference at the membrane of excitable cells. When the membrane potential attenuates to a certain value in the course of depolarization, an action potential is induced via the opening of voltage-dependent ion channels. The value to be reached in each case, which is necessary for the generation of … Threshold Potential: Function, Tasks, Role & Diseases
A Ranvier lacing ring is a ring-shaped interruption of the fat or myelin sheath surrounding nerve fibers. In the course of “saltatoric excitation conduction” it serves to increase the speed of nerve conduction. Saltatoric, from Latin: saltare = to jump refers to the “jump” of an action potential that takes place when it encounters a … Ranvier lacing ring
The active ingredient cisapride is one of the prokinetics that increase motility of the gastrointestinal tract. The active ingredient causes severe cardiac side effects and has therefore been withdrawn from the market in many countries. Its use is not recommended; safer drugs from the prokinetic group are available. What is cisapride? Cisapride belongs to the … Cisapride: Effects, Uses & Risks
Salt is the chemical name for a substance that results from the reaction of an acid with a base. There are three types of salt that are irreplaceable for human growth: Magnesium chloride, potassium chloride and sodium chloride. For this reason, a healthy salt balance is irreplaceable for the body. Salts belong to the mineral … Salt Balance: Function, Tasks, Role & Diseases
The transverse collateral nerve is a purely sensory nerve of the cervical-thoracic region. It originates from spinal cord segments C1 and C2. Damage to the nerve or spinal cord may result in complete loss of skin sensation in the corresponding area. What is the transverse collateral nerve? Depending on how many sensitive fibers and how … Transverse Colliculus Nerve: Structure, Function & Diseases
Propofol is the most commonly used narcotic in general anesthesia and intensive care. It has a sedative, memory– as well as consciousness-suppressing effect and is used in combination with analgesics and muscle relaxants to induce and maintain anesthesia. Its short duration of action makes it very controllable; however, risks and side effects may occur. What … Propofol: Effects, Uses & Risks
The strongest cardiac nerve is the cardiac cervical median nerve. Its origin is in the middle cervical ganglion, and it is involved in the control of cardiac function. Drugs and medications that affect the sympathetic nervous system (sympathomimetics and sympatholytics) can affect cardiac function via the cervical cardiac nerve and the other cardiac nerves. What … Cervical Median Cardiac Nerve: Structure, Function & Diseases
The superior cardiac nerve is a cardiac nerve and extends from the superior cervical ganglion to the cardiac plexus. It is part of the sympathetic autonomic nervous system and primarily influences cardiac function. Certain drugs and medications can enhance (sympathomimetics) or attenuate (sympatholytics) its effects. What is dre superior cardiac nerve? The human body has … Superior Cardiac Nerve: Structure, Function & Diseases
Benzocaine is a drug from the active substance class of local anesthetics. The drug is used primarily in local pain therapy in the area of the skin and mucous membranes. What is benzocaine? Benzocaine is a drug from the active substance class of local anesthetics. Possible forms of application include sprays, powders, ointments, suppositories, and … Benzocaine: Effects, Uses & Risks
