1. Nervous cells are also called
nephrons
nauticals
neurons
nellies
2. The other cells of the nervous system are called
dermal cells
pituitary cells
glial cells, or glia
glandular cells
3. Which of these are parts of a neuron?
dendrites, cell body, axon, myelin sheath, axon terminal
apocrine, holocrine, exocrine, apothecary, process bulbs
thyroid, hypothalamus, epithalamus, epididymis
ileum, duodenum, colon, cecum, rectum, anus
4. What is the myelin sheath made of?
protein
electrolytes
lipids
axillary fibers
5. What are the types of cells that form myelin sheaths?
Duck cells and Oliver-dendrites
Loon cells and Othellocytes
Goose cells and Osmosiscytes
Schwann cells and Oligodendrocytes
6. Which is true of Schwann cells and Oligodendrocytes?
Schwann cells are long and oligodendrocytes are olive-shaped
Schwann cells swim and oligodendrocytes walk
Schwann cells are in the Peripheral Nervous System, oligodendrocytes in the Central Nervous System
Schwann cells and oligodendrocytes often "hold hands" in pairs
7. What are ganglia?
gangs of roving white blood cells
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
8. Where does the action potential usually start?
the axon hillock, or "neck" of the neuron
the middlemost node of Ranvier
the seventh dendrite
the synaptic end bulb
9. What starts an action potential?
only a stimulus
a stimulus from the internal or external environment, or a nearby cell's action potential
nothing, it draws inspiration from its own nucleus
only a nearby cell's action potential
10. What two factors cause an action potential to be faster?
thickness and myelination
bone and muscle
the presence of a third rail
low temperature and whistles
11. Schwann cells creating a myelin sheath along a neuron's axon have been compared to:
a lemonade stand
a highway junction
electric tape around a wire
a hairdryer
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 neuron has an all-or-nothing attitude
the essay on the label of Dr. Bronner's soap
13. Why is gray matter darker than white matter?
gray matter contains the neurons' nuclei, which are darker
gray matter contains more phosphorus
white matter contains more iron
gray and white matter are preparing for a third, secret matter
14. What is the name of the "jumpy" conduction of an action potential across the nodes of Ranvier?
saltatory conduction
stymied conduction
styloid condensation
simple calculation
15. What are nodes of Ranvier?
10 foot long neurons
serifs in the world's first typewriter font
gaps between sections of myelin
train stations in the Alps
