Final answer:
The answer explains myelin sheath gaps, absolute refractory period, and nerve fiber types in neurobiology.
Explanation:
Myelin sheath gaps (Nodes of Ranvier): Regularly spaced gaps in the myelin sheath that allow for rapid transmission of nerve impulses along the axon.
Absolute refractory period: The period after a neuron fires an impulse where it cannot fire another impulse until it is reset.
Group A and group B fibers: Types of nerve fibers classified based on their diameter and speed of conduction.
