GRADED A+
Name the three main parts of a neuron and the direction in which an
action potential travels
Ans: Axons, soma (cell body), and dendrites. Action potentials are
received by dendrites and travel from the cell body down the axon
Quiz: What determines the intensity of an electrical signal for an action
potential?
Ans: Frequency of action potentials
Quiz: List 5 physiological changes that are associated with activation of
the sympathetic nervous system.
Ans: Inhibition of digestion, contraction of sphincters, inhibition of urination,
opening of airways, increased heart rate, increased blood flow to
muscles, sweating, vasoconstriction, emotional vasodilation (blushing),
pupil dilation, release of epinephrine, ejaculation/orgasm
Quiz: What are the 4 lobes of the cerebral cortex and their primary
functions?
Ans: Frontal lobes: voluntary movement, higher order thinking
, Parietal lobes: tactile sensations and gustation
Temporal lobes: audition, olfaction, short-term memory, language
comprehension, emotion
Occipital lobes: vision
Quiz: What are the mediums that sound vibrations travel through, from
when they enter the ear to when they are translated into an electrical
signal in the auditory nerve?
Ans: air (sound waves) → bone (malleus, incus, stapes) → fluid (perilymph
and endolymph in the cochlea)
Quiz: What is Weber's Law?
Ans: Weber's Law says that two stimuli must differ by some constant
proportion to be detected as unique from each other
Quiz: How do peptide hormones and steroid hormones differ in the
duration and immediacy of their effects?
Ans: Peptide hormones tend to work rapidly and temporarily while steroid
hormones tend to work more slowly but have more permanent effects
Quiz: In Baddeley's model, what are the four components of working
memory?
Ans: Phonological loop, visuospatial sketchpad, episodic buffer, central
executive
