Question 1

Question
If a drug speeds up the reuptake of a neurotransmitter, it's an
Answer
  • antagonist
  • agonist

Question 2

Question
If a drug disrupts the production of a neurotransmitter, it's an
Answer
  • agonist
  • antagonist

Question 3

Question
What effect on APs would a glutamate agonist have?
Answer
  • More action potentials (an increase in excitability)
  • Less action potentials (a decrease in excitability)

Question 4

Question
What effect on APs would a GABA agonist have?
Answer
  • More action potentials (an increase in excitability)
  • Less action potentials (a decrease in excitability)
  • Neither, because GABA doesn't influence excitability

Question 5

Question
Signals with neurons are primarily [blank_start]electrical[blank_end]; signals between neurons are primarily [blank_start]chemical[blank_end]
Answer
  • electrical
  • chemical
  • electrical
  • chemical

Question 6

Question
Just after a cell reaches -40mV (at the start of an action potential), as it continues to depolarize, which of the following is/are true?
Answer
  • Na+ ions rush in
  • K+ ions rush in
  • Na+ ions rush out
  • K+ ions rush out

Question 7

Question
The thalamus is the sensory relay center
Answer
  • True
  • False

Question 8

Question
Oligodendrocytes myelinate axons in the PNS
Answer
  • True
  • False

Question 9

Question
Where in the neuron is the decision made to fire?
Answer
  • axon terminals
  • dendrites
  • axon hillock
  • nucleus

Question 10

Question
What do oligodendrocytes do?
Answer
  • Make up one segment of myelin
  • Transfer nutrients from blood cells to neurons and waste from neurons to blood
  • Make up myelin sheath
  • Pick up and destroy debris around the neuron

Question 11

Question
What do glial cells NOT do?
Answer
  • Provide neurons with chemical signals
  • Provide neurons with raw materials
  • Help neurons with specialized structural components
  • Trick question; they do all of these things

Question 12

Question
[blank_start]Glogi[blank_end] stains are good for seeing neuron shapes, while [blank_start]Nissl[blank_end] stains are good for counting neurons
Answer
  • Nissl
  • Golgi
  • Nissl
  • Golgi

Question 13

Question
What can we see with neuron stains?
Answer
  • Specific proteins
  • Action potentials
  • Neuron connectivity
  • Recently active neurons

Question 14

Question

Answer
  • Unipolar
  • Bipolar
  • Multipolar
  • Unipolar
  • Bipolar
  • Multipolar

  • Multipolar

Question 15

Question
Label the functions of each lobe of the brain
Image:
9b0ed2ea-c2e9-4dd3-a0db-326ba1206205 (image/jpeg)
Answer
  • Motor
  • Touch
  • Audition
  • Vision

Question 16

Question
Label the steps of an action potential
Image:
2fd566af-2180-43f1-9a06-263585fe8ebb (image/jpeg)
Answer
  • Resting potential
  • Na+ ligand-gated channels open
  • Threshold! Na+ rushes in
  • K+ voltage-gated channels open, K+ out

Question 17

Question
Label the steps of synaptic communication
Image:
c9945222-3d1c-4c0b-9bed-99b2a394a490 (image/jpeg)
Answer
  • AP reaches axon terminal
  • Ca2+ volt-gate ch. open, Ca2+ rushes in
  • Ca2+ makes the vesicles sticky
  • Vesicles fuse w/cell wall, release NTs
  • NTs bind to receptors
  • Ions depolarize or hyperpolarize cell

Question 18

Question
Glutamate is sent to [blank_start]everywhere[blank_end], from [blank_start]everywhere[blank_end], and is the most predominate [blank_start]excitatory[blank_end] NT in the brain
Answer
  • everywhere
  • everywhere
  • excitatory

Question 19

Question
GABA is sent to [blank_start]everywhere[blank_end], from [blank_start]everywhere[blank_end], and is the most predominant [blank_start]inhibitory[blank_end] NT in the brain
Answer
  • everywhere
  • everywhere
  • inhibitory

Question 20

Question
Agonists [blank_start]increase[blank_end] NT activity and antagonists [blank_start]decrease[blank_end] NT activity
Answer
  • increase
  • decrease

Question 21

Question

Answer
  • True
  • False

Question 22

Question
