saltatory การใช้

• The cuckoos show what is called saltatory or transilient wing moults.
• The length of axons'myelinated segments is important to the success of saltatory conduction.
• Saltatory conduction provides one advantage over conduction that occurs along an axon without myelin sheaths.
• Some diseases degrade myelin and impair saltatory conduction, reducing the conduction velocity of action potentials.
• Together with the Swiss physiologist Robert St鋗pfli, he evidenced the existence of saltatory conduction in myelinated nerve fibres.
• Known as saltatory conduction, this type of signal propagation provides a favorable tradeoff of signal velocity and axon diameter.
• Thus, the safety factor of saltatory conduction is high, allowing transmission to bypass nodes in case of injury.
• By the time the ballerina Agrippina Vaganova began teaching there in 1921, Russia had acquired a trove of saltatory art and experience.
• Saltatory conduction has also been found in the small-and medium-sized myelinated fibers of " Penaeus " shrimp.
• Along unmyelinated fibers, impulses move continuously as waves, but, in myelinated fibers, they " hop " or propagate by saltatory conduction.
• ;Saltatory transmission at nodes of Ranvier : Rapid transmission of the action potential in myelinated axons depends on electrical currents across inactive regions of membrane.
• In general, colonization shows a " saltatory " pattern, as the Neolithic advanced from one patch of fertile alluvial soil to another, bypassing mountainous areas.
• While most larvae have a " cruise and ambush " pattern of feeding, shore fish employ a " saltatory search, " or " pause-travel " feeding pattern.
• A due appreciation of the far-reaching results of correlated variation must, it appeared, give a new and distinct explanation of large mutations, discontinuous variation, and saltatory evolution.
• The views of Hugo de Vries and others about the importance of saltatory variation, the soundness of which was still not generally accepted in 1910, may be gathered from the article Mendelism.
• Although the mechanism of saltatory conduction was suggested in 1925 by Ralph Lillie, the first experimental evidence for saltatory conduction came from Ichiji Tasaki and Taiji Takeuchi and from Andrew Huxley and Robert St鋗pfli.

• Whether saltatory or not, the mean conduction velocity of an action potential ranges from 1 meter per second ( m / s ) to over 100 m / s, and, in general, increases with axonal diameter.
• Instead, the ionic current from an action potential at one node of Ranvier provokes another action potential at the next node; this apparent " hopping " of the action potential from node to node is known as saltatory conduction.
• Saltatory conduction occurs widely in the myelinated nerve fibers of vertebrates, but was later discovered in a pair of medial myelinated giant fibers of " Fenneropenaeus chinensis " and " Marsupenaeus japonicus " shrimp, as well as in a median giant fiber of an earthworm.
