The high fat content of a myelin sheath insulates a neuron from which components of the fluids that encase the nervous system?
A) Electrically charged atoms
B) Dangerous free radicals
C) Toxic cellular wastes
D) Excessive salt molecules

Question

Quizplus · Accepted Answer

The high fat content of a myelin sheath primarily provides electrical insulation for neurons, which helps prevent the electrical charges carried by ions (electrically charged atoms) from dissipating across the neuron's membrane. This insulation is crucial for the efficient transmission of nerve impulses.
