Which statement is true regarding myelin sheaths? A Myelin sheaths are found only on neurons in the peripheral nervous systems B Myelin sheaths allow for action potentials to be transmitted faster within the dendrites of neurons C The spaces between each myelin sheath are referred to as the "Node of Ranvier" D Collections of myelin sheaths within the nervous system give nerve tissue a dark appearance, which is referred as gray matter

Step 1
Myelin sheaths are insulating layers that surround nerves, including those in the brain and spinal cord. They are made of protein and fatty substances, which allows electrical impulses to transmit quickly and efficiently along the nerve cells. Show more…

Which of the following is not correct about myelin sheaths? Select one: They insulate parts of the neuron, including the axon, but not the cell body and dendrites. They increase the speed of action potential conduction along an axon by increasing the diameter of the axon. They are formed by glial cells, namely oligodendrocytes and Schwann cells. They are responsible for saltatory conduction, the process in which the action potentials jump between nodes of Ranvier. They are fatty membranes.

Which of these statements about nervous tissue is not true? a. Neurons have cytoplasmic extensions called axons. b. Electrical signals (action potentials) are conducted along axons. c. Bipolar neurons have two axons. d. Neurons are nourished and protected by glia. e. Dendrites receive electrical signals and conduct them toward the cell body.
