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