The propagation of action potential in myelinated nerve fiber is faster because of-
Show Hint
- Continuous conduction
- Saltatory conduction
- Spontaneous conduction
- Intermittent conduction
The Correct Option is B
Solution and Explanation
In myelinated axons, the action potential jumps between the Nodes of Ranvier in a process called Saltatory conduction. The myelin sheath acts as an insulator, preventing the signal from dissipating and significantly increasing the speed of nerve impulse transmission. This mechanism is far more efficient than continuous conduction in unmyelinated fibers.
Top Questions on Animal Sciences
In a deer species that lives in groups, some individuals act as sentinels and are vigilant for predators but there is a trade-off between foraging and vigilance. A researcher collects data on the foraging rates of edge (black) and central (grey) members of the group in two similar forests, one with and one without predators. Which one of the following figures best supports the hypothesis that members at the edge are acting as sentinels in this deer species?
