T2: Endocrine System / Nature vs Nurture Flashcards
Endocrine System
set of glands that release hormones into the blood
hypothalamus -> pituitary gland -> everything else in the system
Pituitary Gland
master gland of the endocrine system, regulates everything within it.
Adrenal Gland
Sympathetic nervous system, triggers fight or flight responses.
Nature Nurture Debate
genetic or from experience? how much of both?
Critical periods
Periods in which things must develop or they will not work. Ex: animals born with their eyes shut must open them at a certain period or they will never see.
Tryon experiment
selective breeding of “maze-dull” and “maze-bright” rats, cross-fostered.
concluded: genes influence development of behavior.
(pro eugenics)
Cooper and Zubek experiment
redid tryon’s with impoverished vs enriched environments (socialization).
concluded: environment influences behavior.
(anti eugenics)
Phenylketonuria (PKU)
condition in which the body can’t break down an amino acid (phenylalanine).
no treatment: phenylalanine builds up in the blood and causes health problems, including intellectual disability.
treatment: a special diet without phenylalanine, “normal” healthy life.
Epigenetics
Study of heritable changes in gene expression caused by mechanisms other than changes in the underlying DNA.
