Questions and CORRECT Answers
Using 100% of our brain v. 10% - CORRECT ANSWER - We use 100% of our brain!
If we only used 10%, evolution would have precluded us from having such large brains. The brain also uses more
metabolic resources than any other tissue in the body.
Behavioral Neurobiology - CORRECT ANSWER - the scientific study of the biology of behavior
This is a biological approach to the study of psychology
Comparative Approach - CORRECT ANSWER - the study of biological processes by comparing different species
Why are animal brains studied by neuroscientists? - CORRECT ANSWER - They have less ethical restrictions,
comparative approach, nonhuman brains are simpler, thus allowing researchers to get to the foundation of brain-behavior
relations
Human and nonhuman brains are quite similar though, human brains just are larger with more cortical connections
Nervous System - CORRECT ANSWER - brain, spinal cord, nerves
Central Nervous System - CORRECT ANSWER - brain and spinal cord (receives information from PNS and
makes decisions)
Peripheral Nervous System - CORRECT ANSWER - the sensory and motor neurons that connect the CNS to the
rest of the body (sends sensory input to the CNS)
Parasympathetic Nervous System - CORRECT ANSWER - rest and digest, conserve energy, psychological
relaxation
Sympathetic Nervous System - CORRECT ANSWER - fight/flight, mobilize energy, psychological arousal
Meninges - CORRECT ANSWER - three protective membranes that surround the brain and spinal cord
dura mater - CORRECT ANSWER - tough outer layer of the meninges
Arachnoid Mater - CORRECT ANSWER - spider web-like filaments that extend from the dura mater to the pia
mater
subarachnoid space underneath that is FILLED WITH CEREBROSPINAL FLUID and blood vessels
Pia Mater - CORRECT ANSWER - adheres to the surface of the CNS, very thin membrane
Cerebrospinal fluid - CORRECT ANSWER - Cerebrospinal fluid fills the subarachnoid space and ventricles and
cushions the brain
Cushions and protects the brain
Coronal Plane - CORRECT ANSWER - divides body into front and back
Saggital Plane - CORRECT ANSWER - divides the body into a right and left side
Axial Plane - CORRECT ANSWER - A horizontal flat surface dividing the body into upper and lower parts; also
known as the transverse plane
Brain Structure - CORRECT ANSWER - Telencephalon
Diencephalon
, Mesencephalon
Metencephalon
Myelencephalon
Spinal Cord
(The Dog's Mess Met My Shirt)
Telencephalon - CORRECT ANSWER - cortex
basal ganglia
limbic system
Cortex function - CORRECT ANSWER - high level processing
Basal ganglia function - CORRECT ANSWER - motor control
limbic system function - CORRECT ANSWER - attention and motivation
Diencephalon - CORRECT ANSWER - thalamus and hypothalamus
Thalamus function - CORRECT ANSWER - "sensory switchboard"
Relays information to corresponding areas of the brain
Hypothalamus function - CORRECT ANSWER - homeostasis, temperature
Metencephalon - CORRECT ANSWER - Cerebellum and pons
Cerebellum funtion - CORRECT ANSWER - fine motor control
pons function - CORRECT ANSWER - Bridge between various parts of the nervous system, including the
cerebellum and cerebrum.
Myelencephalon - CORRECT ANSWER - Medulla
Medulla function - CORRECT ANSWER - heart rate and breathing
Folia - CORRECT ANSWER - folds of the cerebellum (made up of grey matter)
allows there to be just as many neurons as the rest of the brain in this little structure by being tightly packed, and is
necessary for fine motor control.
What do you call clusters of cell bodies in the CNS? - CORRECT ANSWER - Nuclei
What do you call clusters of cell bodies in the PNS? - CORRECT ANSWER - Ganglia
What do you call a bundle of axons in the CNS? - CORRECT ANSWER - Tracts
What do you call a bundle of axons in the PNS? - CORRECT ANSWER - Nerves
What are glial cells in the CNS? - CORRECT ANSWER - oligodendrocytes
What are glial cells in the PNS? - CORRECT ANSWER - Schwann cells
Bumps on the brain are called...? - CORRECT ANSWER - Gyri
Grooves on the brain are called...? - CORRECT ANSWER - Sulci if small, fissures if big
Fissures & lobes of the brain - CORRECT ANSWER -
