What would be the best explanation for why myelinated fibers conduct signals faster than unmyelinated fibers?
Sliva [168]

Answer: The diffusion of ions along the axoplasm is faster,in myelinated compare to unmyelinated,

Neurons are the structural and functioning units of nervous system.They are the vehicles for transmission of impulses as electrical signals from one part of the cells,and from one part of the body to another.

The basic structural components of a typical neuron are the cellbody, the axon, and the dendrites.

Based on structure neurons are classified as myelinated and unmyelinated.This is based on the the surrounding layer of myelin sheath around the axon. The myelin provides the insulating layer for the axon.And ensures fast movement of impluses.

In myelinated neurons the myelin sheath are interrupted at intervals by gaps along the length of the axon called Nodes of Ranvier. These gaps contains more Na-K channels for influx and out-flux of K and Na+ ions for transmission of impulses.

The cytoplasm of axon is called axoplasm,Since this is surrounded by myelin sheath which contains Na-K+ channels,The rate of diffusion of ions along  these channels is faster for depolarization to take place than in unmyelinated neurons. Inaddtion as these ions  diffusion increases,its jump faster at the nodes of Ranvier (saltatory conduction) to the next axoplasm which further speed up the rate of transmission.

Unmyeinated lacks myelin sheath,therefore the exchange and  the rate of diffusion of ions along the axons is low.

What is a radioactive isotope?
saul85 [17]

B. An atom whose nucleus is unstable and emits particles and and energy. This is a Radioactive isotope.

The atomic nuclei of constituent atoms of the same element include the same number of protons but different numbers of neutrons. Radio isotopes are an element's radioactive isotopes. They can alternatively be described as atoms with an excess of energy in their nucleus or atoms with an unstable ratio of neutrons to protons. A radioisotope's unstable nucleus can form either spontaneously or as a result of a deliberate alteration of the atom. Radioisotope production can occur using either a cyclotron or a nuclear reactor. Molybdenum-99, which has a high neutron content, can be produced most effectively in nuclear reactors, whereas fluorine-18, which has a high proton content, can be produced most effectively in cyclotrons. Uranium is the most well-known illustration of a radioisotope that is found naturally. Uranium-238 constitutes all naturally occurring uranium with the exception of 0.7%.
