What are the thin fibers of the human nervous system that send messages between different parts of the body

Neurons

Explanation:

Neurons run through our body and communicate with each other. They send/receive messages from other parts of the body

Neurons.

Explanation: Neurons, a part of the brain, and something that no human being could function without, send messages to each other and allow the body to properly function.

answer: i cant find your answer. do u have another way i can answer it for you : )

explanation:

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
