1. Nervous cells are also called
nellies
neurons
nephrons
nauticals
2. The other cells of the nervous system are called
glial cells, or glia
dermal cells
pituitary cells
glandular cells
3. Which of these are parts of a neuron?
ileum, duodenum, colon, cecum, rectum, anus
apocrine, holocrine, exocrine, apothecary, process bulbs
dendrites, cell body, axon, myelin sheath, axon terminal
thyroid, hypothalamus, epithalamus, epididymis
4. What is the myelin sheath made of?
protein
lipids
electrolytes
axillary fibers
5. What are the types of cells that form myelin sheaths?
Schwann cells and Oligodendrocytes
Duck cells and Oliver-dendrites
Goose cells and Osmosiscytes
Loon cells and Othellocytes
6. Which is true of Schwann cells and Oligodendrocytes?
Schwann cells are in the Peripheral Nervous System, oligodendrocytes in the Central Nervous System
Schwann cells swim and oligodendrocytes walk
Schwann cells are long and oligodendrocytes are olive-shaped
Schwann cells and oligodendrocytes often "hold hands" in pairs
7. What are ganglia?
oval-shaped clusters of nerve cells, usually found outside the Central Nervous system and functioning as relay stations
new fabrics made of carbon waste
evil muppets
gangs of roving white blood cells
8. Where does the action potential usually start?
the synaptic end bulb
the middlemost node of Ranvier
the axon hillock, or "neck" of the neuron
the seventh dendrite
9. What starts an action potential?
nothing, it draws inspiration from its own nucleus
a stimulus from the internal or external environment, or a nearby cell's action potential
only a stimulus
only a nearby cell's action potential
10. What two factors cause an action potential to be faster?
thickness and myelination
the presence of a third rail
low temperature and whistles
bone and muscle
11. Schwann cells creating a myelin sheath along a neuron's axon have been compared to:
a lemonade stand
a highway junction
a hairdryer
electric tape around a wire
12. The "all-or-none law" refers to:
an action potential happens at a fixed speed or doesn't happen at all
the electric current is either yellow or purple
the essay on the label of Dr. Bronner's soap
the neuron has an all-or-nothing attitude
13. Why is gray matter darker than white matter?
gray and white matter are preparing for a third, secret matter
white matter contains more iron
gray matter contains more phosphorus
gray matter contains the neurons' nuclei, which are darker
14. What is the name of the "jumpy" conduction of an action potential across the nodes of Ranvier?
saltatory conduction
stymied conduction
simple calculation
styloid condensation
15. What are nodes of Ranvier?
serifs in the world's first typewriter font
gaps between sections of myelin
train stations in the Alps
10 foot long neurons
