What is antidromic conduction?

the conduction of a nerve impulse in a reversed direction (i.e., from axon to cell body), produced for experimental purposes. Also called antidromic activation; antidromic phenomenon.

Does a nerve impulse travels electrically across a synapse?

Where two neurons meet there is a small gap called a synapse . An electrical impulse cannot directly cross the gap so a different mechanism has to be used. These chemicals diffuse across the synapse (the gap between the two neurons).

What is neurotransmitter transmission?

neurotransmitter A chemical released at the end of a neuron to carry a message to a neighboring cell. This chemical travels across the space between two cells, and then binds to molecules on a neighboring cell to transmit a message.

What are antidromic action potentials?

An antidromic impulse in an axon refers to conduction opposite of the normal (orthodromic) direction. For most neurons, their dendrites, soma, or axons are depolarized forming an action potential that moves from the starting point of the depolarization (near the cell body) along the axons of the neuron (orthodromic).

What is the definition Antidromic?

Definition of antidromic : proceeding or conducting in a direction opposite to the usual one —used especially of a nerve impulse or fiber.

What does Nondecremental mean?

the propagation of a nerve impulse along an axon in which the amplitude of the impulse is maintained as it progresses. Compare decremental conduction.

How a nerve impulse is transmitted?

A nerve impulse is transmitted to another cell at either an electrical or a chemical synapse . At a chemical synapse, neurotransmitter chemicals are released from the presynaptic cell into the synaptic cleft between cells.

How does a neuron transmit a nerve impulse?

Neurotransmitters travel across the synapse between the axon and the dendrite of the next neuron. Neurotransmitters bind to the membrane of the dendrite. The binding allows the nerve impulse to travel through the receiving neuron.

Do you obtain an action potential if the impulse is Antidromic?

(2009) have concluded that reliable action potentials can be obtained in antidromic recordings at 25\% of the stimulus intensity that would generate a maximal response.

Is WPW Antidromic or orthodromic?

Only about 5\% of the tachycardias in patients who have WPW syndrome are antidromic tachycardias; the remaining 95\% are orthodromic.
