Physio Chapter 6 Question and answers
100% correct 2025
Motivation - correct answer I. Internal states of the brain can act as
motivators and make us behave in certain ways
II. the set of factors that initiate, sustain, and direct behaviors
Theoretical approaches - correct answer I. Instinct
II. Arousal theory
III. Drive theory
Instinct - correct answer I. automatic behavior that's complex and unlearned
- Ex. migration and maternal behavior in animals
II. a complex behavior that is automatic and unlearned, and occurs in all
members of a species, such as maternal behavior.
Arousal theory - correct answer I. We're born with an idling speed; we have
our own level of physiological arousal that's our optimum arousal level
II. People with usually high idling speeds are going to seek activities that will
maintain this level of arousal and people with low idling speeds don't like
much stimulation
- ex. adrenaline junkies and couch potatoes
III. People behave in ways that keep them at their preferred level of arousal
Drive theory - correct answer I. For the systems that operate like this (ex.
water in the body, temp, blood sugar levels, etc), we have an equilibrium point
with some individual differences
, II. Departure from this set point will cause us to act in ways to put our body
back in equilibrium
- ex. cold = warm up, hot = cool down, lack of water = thirsty
III. Originate in the brain ONLY
Homeostatic drives - correct answer I. A "control system" maintains
conditions around a set point.
- ex. sex and hunger
II. Simple and complex
- Thirst and temperature are similar to a thermostat
III. Negative feedback systems are the primary mechanism
Set point - correct answer the point of equilibrium the system returns to.
Hypothalamus - correct answer I. Regulates all biological drives, including the
homeostatic drives
- Direct link to pituitary gland
II. A structure that includes jelly bellies (nuclei), and each of the jelly bellies
are involved with a certain biological drive
- Different areas of the hypothalamus that are involved with a specific drive
- Ex. preoptic nuclei are involved in temp. regulation (possibly involved in
thirst regulation)
Temperature Regulation - correct answer I. Endotherms regulate their body
temperature by dilating or constricting blood vessels, adjusting metabolism,
sweating, etc.
II. Warmth-sensitive and cold-sensitive cells in the preoptic area of the
hypothalamus receive input from the blood and the skin.
