Nodes of Ranvier are microscopic gaps in the myelin sheath that surrounds the axon of a neuron.

Answer: A 
 The cell body, also known as the soma, contains the nucleus and other organelles necessary for the function of the neuron.

Answer: B 
 The axon is a long, thin extension of the neuron that transmits electrical impulses away from the cell body.

Answer: D 
 Dendrites are shorter, branching extensions of the neuron that receive signals from other neurons and transmit them to the cell body.

Answer: E 
 Myelin is a fatty substance that surrounds and insulates the axon, speeding up the transmission of electrical impulses.

Answer: F 
 Neurofibrils are thread-like structures within the neuron that provide structural support and help transport substances throughout the cell.
