1. Nervous cells are also called
nephrons
neurons
nauticals
nellies
2. The other cells of the nervous system are called
dermal cells
glandular cells
glial cells, or glia
pituitary cells
3. Which of these are parts of a neuron?
ileum, duodenum, colon, cecum, rectum, anus
dendrites, cell body, axon, myelin sheath, axon terminal
apocrine, holocrine, exocrine, apothecary, process bulbs
thyroid, hypothalamus, epithalamus, epididymis
4. What is the myelin sheath made of?
axillary fibers
electrolytes
lipids
protein
5. What are the types of cells that form myelin sheaths?
Loon cells and Othellocytes
Duck cells and Oliver-dendrites
Goose cells and Osmosiscytes
Schwann cells and Oligodendrocytes
6. Which is true of Schwann cells and Oligodendrocytes?
Schwann cells and oligodendrocytes often "hold hands" in pairs
Schwann cells are long and oligodendrocytes are olive-shaped
Schwann cells are in the Peripheral Nervous System, oligodendrocytes in the Central Nervous System
Schwann cells swim and oligodendrocytes walk
7. What are ganglia?
new fabrics made of carbon waste
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
8. Where does the action potential usually start?
the middlemost node of Ranvier
the seventh dendrite
the axon hillock, or "neck" of the neuron
the synaptic end bulb
9. What starts an action potential?
only a nearby cell's action potential
a stimulus from the internal or external environment, or a nearby cell's action potential
only a stimulus
nothing, it draws inspiration from its own nucleus
10. What two factors cause an action potential to be faster?
low temperature and whistles
thickness and myelination
bone and muscle
the presence of a third rail
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 neuron has an all-or-nothing attitude
the essay on the label of Dr. Bronner's soap
the electric current is either yellow or purple
13. Why is gray matter darker than white matter?
white matter contains more iron
gray matter contains the neurons' nuclei, which are darker
gray matter contains more phosphorus
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?
simple calculation
styloid condensation
stymied conduction
saltatory conduction
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
