Question 2 of 18 Which statement is NOT true about the cells of the nervous system? Select the correct response: A neuron can have only one axon. A neuroglial cell supports or protects a neuron. There may be multiple dendrites on a single cell. A dendrite is the cell part that carries an electrical impulse away from the cell body. A dendrite is a cytoplasmic extension of a neuron. O O

Which of the following neuron structure - function parings is incorrect? Axon - extension of cell body Dendrite - sensitive to chemical and electrical signals Cell body - contains cell nucleus Axon - transmits signals to neighboring cells Dendrite - unbranched receptor sites of signals from other neurons
Which of the following is NOT true of glial cells? O They form the myelin for axons. O They are outnumbered 10 to 1 by neurons in the nervous system. They deliver fuel molecules to neurons and remove the waste products of metabolism. O They are important for the growth and development of the nervous system. O They regulate the composition of the extracellular fluid in the CNS.

O Compromising the inactivation mechanism in voltage-gated Na* channels. O Stimulating the voltage-gated K* channels. O Inhibiting the voltage-gated Na* channels. O Compromising the inactivation mechanism in voltage-gated K* channels.

What is similar about the Autonomic and Somatic Nervous Systems? O Both have smooth muscle as effectors Both can send information to the Central Nervous System through afferent neural pathways Both have skeletal muscle as effectors Both are part of the Efferent (Motor) Division of the Nervous System
The membrane of a neuron is vital to its ability to respond to signals from other neurons. Which of the following statements about this membrane is NOT accurate It ensures that the interior of the cell has a slightly positive charge at rest. It is selectively permeable, allowing ions to move in and out of the cell. It contains different types of specialized protein ion channels. It is made of two layers of lipids (fat molecules)

Researchers have designed a neuron that's unable to produce and release neurotransmitters. Can that neuron still have an action potential? Choose the answer with the correct answer and the correct reasoning. O No, action potentials need neurotransmitters to increase message speed O No, a neuron can't receive messages without its own neurotransmitters O No, a lack of neurotransmitters would leave a neuron unmyelinated O No, action potentials don't occur in the axon O Yes, action potentials don't require neurotransmitters:
You are studying a cross-sectional tissue slice of a nerve using a transmission electron microscope. You find an area where there appears to be a small amount of cytoplasm surrounded by about 100 layers of stacked cell membranes. You conclude that you have found a neuron cell body.
