Ch. 3 - Biopsychology Flashcards
genotype
the genetic makeup of an individual based on the genetic material (DNA) inherited from one’s parents
phenotype
an individual’s observable characteristis, such as hair color, skin color, height, and build
range of reaction
asserts our genes set the boundaries within which we can operate, and our environment interacts with the genes to determine where in that range we will fall
genetic-environment correlation
view of gene-environmental interactions that asserts our genes affect our environment, and our environment influences the expressions of our genes
epigenetics
study of gene-environment interations such as how the same genotype leads to different phenotypes
two types of cells of the nervous system
glial (glia) and neurons
soma
cell body
axon
carries never impulses away from the cell body
dendrite
wherea neuron receives input from the other cells
axon terminal
end of axon responsible for providing synapse neurons
myelin
layer of fat that helps impluses to travel quick and efficiently
synapse
the space between the terminal button of one neuron and the dendrite of another neuron
action potential
the propagation of signals along the neuron’s axon toward synaptic boutons situated at the ends of an axon
dopamine
mood, sleep, learning; increased pleasure, suppressed appetite
serotonin
mood, sleep; modulated mood, suppressed appetite
