Question Answer
deep groove in the cerebellumtransverse fissure
membrane in transverse fissure of cerebellum that supports posterior cerebrumtentorium cerebelli
part of cerebellum that separates the hemispheresvermis
what the cerebellar hemispheres are calledwings
lobes in each wing of the cerebellumanterior, middle, posterior
separate lobes of cerebellar wingsfissures
lobes of cerebellum that govern subconscious aspects of skeletal musclesanterior and posterior
lobe of cerebellum that contributes to equilibrium and balanceflocculondular
parallel rows of gray matter in cerebellar cortexfolia
white matter located deep within gray matter of cerebellar cortex that carries impulse from cerebellum to other parts of braincerebellar nuclei within arbor vitae
bunches of axons that conduct impulses from cerebellum to rest of braincerebellar peduncles
3 cerebellar pedunclesinferior (ICP), middle (MCP), superior (SCP)


Question Answer
what diencephalon connectsbrain stem to cerebrum
what is contained by the diencephalonthalamus, hypothalamus, epithalamus
relay station for sensory infothalamus
plays a major role in arousalthalamus
if this part of your brain is ddamaged you can go into a comathalamus


Question Answer
most pivotal area of brain for control of homeostasishypothalamus
emotions of the hypothalamussexual arousal, rage, aggression
part of hypothalamus that is a relay station for reflexesmammillary region
important functions of hypothalamuscontrol ANS, produce hormones, regulates emotions/behavior patterns, regulate eating/drinking, regulate sleep


Question Answer
location of epithalamusposterior to thalamus
gland contained by thalamuspineal
hormone secreted by pineal glandmelatonin
size of the pineal glandpea
organs around ventricles of brain without complete blood brain barriercircumventricular organs


Question Answer
largest portion of the braincerebrum
seat of intelligencecerebrum
matter in cerebrumouter rim of gray matter and inner white matter
outer ring of gray matter in cerebrumcerebral cortex
folds of cerebrum that form in fetusgyri
indentations in cerebrum more shallow than gyrisulcus
connects right and left hemispheres of cerebrumcorpus callosum
largest white matter area in the braincorpus callosum
separates frontal from parietal lobecentral sulcus
contains motor area of cerebral cortexprecentral gyrus
location of precentral gyrusanterior to central sulcus
location in cerebrum of primary somatosensory areapostcentral gyrus
location of postcentral gyrusposterior to central sulcus
separates frontal from temporal lobelateral cerebral sulcus (fissure)
separates parietal from occipital lobeparieto-occipital sulcus
4 lobes of cerebrumfrontal, parietal, temporal, occipital

Cerebral white matter

Question Answer
what cerebral white matter is mostly composed ofmyelinated axons
conduct nerve impulses between gyri in same hemisphereassociation tracts
conduct nerve impulses between gyri in one hemisphere to the corresponding one on the other sidecommissural tracts
conduct impulses from cerebrum to lower parts of CNS (spinal cord, brain stem)projection tracts

Basal nuclei (formerly ganglia)

Question Answer
paired clusters of gray matter deep in each cerebral hemispherebasal nuclei
3 basal nucleicaudate nucleus, putamen, globus pallidus
an area in the interior of each cerebral hemisphere composed of caudate and lentiform nuclei and white matter of internal capsulecorpus striatum
what corpus striatum doesworks with cerebellum to control muscle activity
area of brain most commonly associated with Alzheimer'sbasal nuclei (corpus striatum?)
distinct structural abnormalities in someone with Alzheinersloss of neurons that liberate AChe, beta-amyloid plaques, neurofibrillary tangles
clusters of abnormal proteins deposited outside neuronsbeta-amyloid plaques
abnormal bundles of filaments inside neurons in affected brain regions with too many phosphate groups

Limbic System

Question Answer
part of brain that plays a part in strong emotions and efficiency of memorylimbic system
first part of brain that suffers from Alzheimerslimbic system
limbic lobe that regulates blood pressure and heart rate that goes along with emotional processingcicgulate gyrus
special memory limbic lobeparahippocampal gyrus
limbic lobe that would tell you where everything in your house isparahippocampus
area for long term memoryhippocampus
part of limbic system that contributes to new memoriesdentate gyrus, mammilary bodies of hypothalamus
part of limbic system that sends fear and reward to cortex, maintaining memories attached to emotionsamygdala
carries info to hippocampus and mammillary bodies, then to amygdalafornix
components of the limbic systemseptal nuclei, mammillary bodies, anterior and medial nucleus, olfactorty bulbs, fornix, stria terminalis/medullaris, forebrain bundle

Brain Injuries

Question Answer
when impact on brain causes temporary loss of consciousness and affects memoryconcussion
bruising of the brain where consciousness is lost for 5 minutescontusion
cut or tear in the brain like from a gunshotlaceration
area with ability to understand spoken wordsBroca's
