1. Nervous cells are also called
neurons
nephrons
nauticals
nellies
2. The other cells of the nervous system are called
pituitary cells
glandular cells
glial cells, or glia
dermal cells
3. Which of these are parts of a neuron?
thyroid, hypothalamus, epithalamus, epididymis
apocrine, holocrine, exocrine, apothecary, process bulbs
ileum, duodenum, colon, cecum, rectum, anus
dendrites, cell body, axon, myelin sheath, axon terminal
4. What is the myelin sheath made of?
protein
axillary fibers
lipids
electrolytes
5. What are the types of cells that form myelin sheaths?
Schwann cells and Oligodendrocytes
Loon cells and Othellocytes
Goose cells and Osmosiscytes
Duck cells and Oliver-dendrites
6. Which is true of Schwann cells and Oligodendrocytes?
Schwann cells and oligodendrocytes often "hold hands" in pairs
Schwann cells swim and oligodendrocytes walk
Schwann cells are long and oligodendrocytes are olive-shaped
Schwann cells are in the Peripheral Nervous System, oligodendrocytes in the Central Nervous System
7. What are ganglia?
evil muppets
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
8. Where does the action potential usually start?
the synaptic end bulb
the axon hillock, or "neck" of the neuron
the seventh dendrite
the middlemost node of Ranvier
9. What starts an action potential?
a stimulus from the internal or external environment, or a nearby cell's action potential
only a nearby cell's action potential
nothing, it draws inspiration from its own nucleus
only a stimulus
10. What two factors cause an action potential to be faster?
the presence of a third rail
low temperature and whistles
thickness and myelination
bone and muscle
11. Schwann cells creating a myelin sheath along a neuron's axon have been compared to:
a lemonade stand
a hairdryer
a highway junction
electric tape around a wire
12. The "all-or-none law" refers to:
the essay on the label of Dr. Bronner's soap
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
13. Why is gray matter darker than white matter?
gray matter contains more phosphorus
gray matter contains the neurons' nuclei, which are darker
gray and white matter are preparing for a third, secret matter
white matter contains more iron
14. What is the name of the "jumpy" conduction of an action potential across the nodes of Ranvier?
stymied conduction
saltatory conduction
simple calculation
styloid condensation
15. What are nodes of Ranvier?
10 foot long neurons
serifs in the world's first typewriter font
train stations in the Alps
gaps between sections of myelin
