Quizplus · Accepted Answer

Myelin is the fatty sheath around nerve fibers made by Schwann cells.

Answer: A
 The cell body contains the nucleus and other organelles, and is responsible for producing proteins, energy, and neurotransmitters.

Answer: C
 Nodes of Ranvier are gaps in the myelin sheath where axons are exposed and where action potentials are regenerated.

Answer: B
 Axons are long, slender projections that conduct electrical signals away from the cell body and towards other neurons.

Answer: D
 Dendrites are branching extensions that receive signals from other neurons and transmit them towards the cell body.

Answer: F
 Neurofibrils are long, thin fibers that provide structural support to neurons and help transport substances throughout the cell.
