Dendrites are the branching fibers that receive a nervous impulse and transmit it towards the cell body.

Answer: A
 Axons are fibers that carry nerve impulses away from the cell body and towards other neurons or muscles.

Answer: E
 The myelin sheath is a fatty insulating material that covers some axons, which helps to speed up the conduction of nerve impulses.

Answer: G
 Oligodendroglia are glial cells in the central nervous system that produce the myelin sheath around axons.
