What is the meaning of all-or-none?
[ ôl′ər-nŭn′ ] Characterized by either a complete response or by a total lack of response or effect, depending on the strength of the stimulus.
What is all or nothing response?
The all-or-none law is a principle that states that the strength of a response of a nerve cell or muscle fiber is not dependent upon the strength of the stimulus. Essentially, there will either be a full response or there will be no response at all for an individual neuron or muscle fiber.
What is a word for all-or-nothing?
Words related to all-or-nothing uncompromising, inflexible, unyielding, hard-line, adamant, firm, unbending.
What is the all or none principle in psychology quizlet?
The all-or-none law is the principle that the strength by which a nerve or muscle fiber responds to a stimulus is independent of the strength of the stimulus. If the stimulus exceeds the threshold potential, the nerve or muscle fiber will give a complete response; otherwise, there is no response.
What does it mean to say that action potentials are all or none quizlet?
What does it mean, that action potentials are all or none? The action potential will be the same size, no matter what the size of the triggering stimulus, as long as threshold is reached.
Which is the correct all or none response?
During baseline, responding by two of the three dyads (W:K, W:M) was characterized by an approximately even division between the LL and RR order-of-responding category (the alternating all-or-none response pattern observed previously). (The other subject’s percentage of responding was 100% minus the percentage shown.)
What is the all or none law for nerves and muscles?
All-or-None Law for Nerves and Muscles. The all-or-none law is a principle that states that the strength of a response of a nerve cell or muscle fiber is not dependent upon the strength of the stimulus.
When is there a full response or there is no response?
Essentially, there will either be a full response or there will be no response at all for an individual neuron or muscle fiber. If a stimulus is strong enough, an action potential occurs and a neuron sends information down an axon away from the cell body and toward the synapse.
What is the definition of all or none?
all-or-none phenomenon. The property of cardiac muscle in which stimulation from a single myocyte travels to the atrium and ventricle before contracting, resulting in a coherent and co-ordinated pump activity.
