One way to tell the difference between a dendrite and an axon is that dendrites usually * a) form branches perpendicular to the main trunk of the dendriteb) are longer than the axon c) are covered with myelin d) taper in diameter toward their periphery2. An interneuron is * a) a glia cell that separates one neuron from another b) a neuron that receives all its information from other neurons and conveys impulses only to other neurons c) a neuron that has its cell body in the spinal cord and an axon that extends to a muscles or gland d) a cell whose properties are halfway between those of a neuron and those of a glia cell 3. A neuron that conveys information toward the hippocampus is considered a (an) __________ cell, with regards to the hippocampus. * a) afferent b) efferent c) intrinsic d) motor 4. A neuron that conveys information away from the hippocampus is considered a (an) _________ cell, with regards to the hippocampus. * a) afferent b) efferent c) intrinsic d) motor 5. A neuron that has an axon and dendrites that branch diffusely, but only extend within a small radius, is probably a (an) ___________. * a) Purkinje cell b) motor neuron in the spinal cord c) interneuron d) sensory neuron 6.In the human brain, glia cells are * a) larger than neurons b) capable of transmitting impulses when neurons fail to do so c) more numerous than neurons d) like neurons, expect that they lack axons 7. One function NOT performed by glia is to * a) remove waste materials b) build myelin sheaths c) transmit information d) guide the growth of axons and dendrites 8. How does the structure of neurons change when an older person becomes senile? *a) No structural change occurs b) Neurons develop new but inappropriate connections c) Many neurons die and dendrites branch less widely in the remainder d) The diameter of axons and cell bodies decreases9. the difference in voltage between the inside and the outside of a neuron that typically exists is called the * a) concentration gradient b) generator potential c) resting potential d) shock value 10. What is meant by the term “concentration gradient”? * a) Sodium ions are more concentrated inside the cell and potassium ions are more concentrated outside b) Potassium ions are more concentrated inside the cell and sodium ions are more concentrated outside c) Sodium ions are more concentrated un the dendrites and potassium ions are more concentrated in the axon d) Potassium ions are more concentrated in the dendrites and sodium ions are more concentrated in the axon 11. The sodium potassium pump pumps sodium ions ___________ and potassium ions _____________. * a) into the cell, into the cell b) into the cell, out of the cell c) out of the cell, out of the cell d) out of the cell, into the cell 12. The sodium potassium pump makes possible which of the following features of a neuron? * a) Refractory period b) Resting potential c) Selective permeability d) Saltatory conduction 13. When the neuron is at rest, which of the following forces tends to move potassium ions OUT of the cell? * a) Concentration gradientb) Electrical gradient c) Both concentration gradient and electrical gradient d) Sodium potassium pump 14.If a stimulus shifts the potential inside a neuron from the resting potential to a more negative potential, the result is * a) hyperpolarization b) depolarizationc) an action potential d) a threshold15. If a stimulus shifts the potential inside a neuron from the resting potential to a potential slightly closer to zero, the result is known as * a) hyperpolarization b) depolarization c) selective permeability d) the refractory period16. A membrane produces an action potential whenever the potential across it reaches * a) the resting potential b) 90 mV c) the threshold d) the myelin sheath17. The two kinds of cells in the nervous system are ________, which receive and transmit information to other cells, and ________, which do not transmit information. * a) neurons, glia b) glia, hypoglia c) glia, neurons d) neurons, corpuscles 18. The outer surface of a cell is called the ________ and the fluid inside the cell is the ________. * a) cytoplasm, endoplasm b) membrane, nuclear fluid c) well, goo d) membrane, cytoplasm 19. The main feature that distinguishes a neuron from other cells is the neuron’s * a) larger nucleus b) ability to metabolize a variety of fuels c) high internal concentration of sodium ions d) varied shape 20. Which part of a neuron contains the nucleus? * a) cell body b) dendrites c) axon d) presynaptic ending21.
