myelin sheath
What makes up the CNS?
spine & brain
What is the difference between nature vs. nurture?

pituitary gland
What is the belief in improving the genetic quality of a human population by controlling reproduction to increase desirable traits & decrease undesirable ones called?
eugenics
Which dream theory suggests that the brain engages in a lot of random neural activity?
activation-synthesis theory
Which lobe controls body position?
parietal lobe

What happens to the sleep stages over the course of the night?
more time in REM, less time in Stage 3
Which part of the brain controls your senses?
thalamus
What is the electrical charge that travels down an axon called?
action potential
What are motor neurons responsible for?
Carries outgoing information from the CNS to the PNS & muscles
What is the inherited likelihood of developing specific traits or conditions due to genetic factors from biological parents called?
genetic predisposition
