BIOL4100: MOTIVATION EXAM QUESTIONS AND ANSWERS
WITH COMPLETE SOLUTIONS VERIFIED LATEST UPDATE
Humoral Response
Hypothalamus stimulates or inhibits release of pituitary hormones as a result of sensory
stimulation
Visceromotor Response
Hypothalamus adjusts the balance of sympathetic and parasympathetic divisions of the
ANS as a result of sensory stimulation
Somatic Motor Response
Hypothalamus elicits somatic motor behavioral responses as a result of sensory
stimulation
Prandial State
High level of nutrients in blood following food consumption
Energy Storage
Glycogen, triglyceride, and anabolism
Glycogen
Finite capacity in liver and skeletal muscle
Triglyceride
Unlimited capacity in adipose tissue
Anabolism
Assembly of macromolecules
, Postabsoptive State
Fasting condition between meals
Energy Storage in Postabsoptive State
Stored glycogen and triglycerides
Disregulation
Obesity, starvation, and catabolism
Obesity
Intake/storage > usage
Starvation
Intake/storage < usage
Catabolism
Breaking down complex macromolecules
Lipostatic Hypothesis
The brain monitors body fat levels and defends it
The OB Gene
OB gene encodes protein signaling normal fat reserves
Parabiosis Experiment
Parabiosis decreased food consumption in OB/OB mice (lacking OB gene)
Leptin
Encoded by OB gene, released by adipocytes, act directly on hypothalamic neurons,
and reverses OB/OB obesity
Bilateral Lesions of the Lateral Hypothalamus
Anorexia and lateral hypothalamic syndrome
