Nerve cells that conduct electrical impulses are called

Neurons

Explanation:

The nervous system is composed of cells called nerve cells. The nerve cells responsible for conducting nerve impulses are called Neurons. Neurons are specialized cells that carry/conduct messages (nerve impulses). These nerve impulses are electrical signals.

All neurons have the same basic parts although their shape may differ depending on the job they carry out.

The Cell body; controls the cell

The Axon or nerve fibre; transmits electrical signals from the cell body

Dendrites; are branched parts that receive electrical signals from other neurons

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
