What is an Afterpotential?

Medical Definition of afterpotential : the sequence of electrical events that follows the action potential of nerve activity and that usually takes the form of a negative followed by a positive potential with both being of much smaller amplitude than the action potential — compare prepotential.

What is the meaning of Philosophia?

Philosophy (from Greek: φιλοσοφία, philosophia, ‘love of wisdom’) is the study of general and fundamental questions, such as those about existence, reason, knowledge, values, mind, and language.

What corresponds to positive Afterpotential?

(Readers familiar with the terminology developed when all records were obtained with extracellu- lar electrodes will recognize that an afterhyperpolarization corresponds to the positive afterpotential of the older terminology and that an afterdepolarization corresponds to the negative afterpotential of that terminology …

What is Orthodromic conduction *?

An antidromic impulse in an axon refers to conduction opposite of the normal (orthodromic) direction. That is, it refers to conduction along the axon away from the axon terminal(s) and towards the soma.

Does the resting membrane potential of a neuron change if the extracellular K+ is increased?

increase the membrane potential (hyperpolarize the cell) because the presence of extra potassium outside the cell will make the potassium equilibrium potential more negative. increase the membrane potential because the excess positive charge on the outside of the cell makes the inside relatively more negative.

What is Orthodromic conduction of the action potential?

An orthodromic impulse runs along an axon in its anterograde direction, away from the soma. In the heart, orthodromic may also refer to an impulse going in the correct direction from the dendrites to axon terminal (from the atria to the ventricles) in contrast to some impulses in re-entry.

What discovery displaced the notion that nerves communicate with the brain by the movement of fluid from the ventricles choose the correct option?

What discovery displaced the notion that nerves communicate with the brain by the movement of fluid from the ventricles? Galvani and Bois-Reymond showed that muscles twitch when nerves are stimulated electrically.

What is the medical definition of ” afterpotential “?

Medical Definition of afterpotential. : the sequence of electrical events that follows the action potential of nerve activity and that usually takes the form of a negative followed by a positive potential with both being of much smaller amplitude than the action potential — compare prepotential.

What does the term philosophy literally mean?

Quite literally, the term “philosophy” means, “love of wisdom.”. In a broad sense, philosophy is an activity people undertake when they seek to understand fundamental truths about themselves, the world in which they live, and their relationships to the world and to each other.
