Pregunta 1
Pregunta
If a drug speeds up the reuptake of a neurotransmitter, it's an
Respuesta
-
antagonist
-
agonist
Pregunta 2
Pregunta
If a drug disrupts the production of a neurotransmitter, it's an
Respuesta
-
agonist
-
antagonist
Pregunta 3
Pregunta
What effect on APs would a glutamate agonist have?
Respuesta
-
More action potentials (an increase in excitability)
-
Less action potentials (a decrease in excitability)
Pregunta 4
Pregunta
What effect on APs would a GABA agonist have?
Respuesta
-
More action potentials (an increase in excitability)
-
Less action potentials (a decrease in excitability)
-
Neither, because GABA doesn't influence excitability

Pregunta 15
Pregunta
Label the functions of each lobe of the brain
Respuesta
-
Motor
-
Touch
-
Audition
-
Vision
Pregunta 16
Pregunta
Label the steps of an action potential
Respuesta
-
Resting potential
-
Na+ ligand-gated channels open
-
Threshold! Na+ rushes in
-
K+ voltage-gated channels open, K+ out
Pregunta 17
Pregunta
Label the steps of synaptic communication
Respuesta
-
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
