Brain Anatomy
This type of brain matter contains cell bodies, dendrites, and synapses with very little myelin.
Gray matter
This clear, colorless fluid fills the ventricles and surrounds the brain and spinal cord.
Cerebral spinal fluid
This brain region regulates hunger, thirst, temperature, and hormone release.
hypothalamus
This sleep stage is known for vivid dreaming and muscle paralysis.
REM sleep
This type of stroke results from a blockage such as a blood clot or atherosclerotic plaque.
ischemic stroke
This structure is a network of cavities which houses cerebral spinal fluid in the brain.
ventricles
This barrier consists of tight junctions between endothelial cells, protecting brain tissue from harmful substances.
Blood-brain barrier
This bulging anterior structure contains cranial nerves V–VIII and regulates sleep, posture, and breathing.
pons
This stage of sleep lasts 10-25 minutes in the initial sleep cycle. Shows EEG frequency decreases but amplitude increases and 1-2 seconds of sleep spindles.
stage 2
This type of stroke results from a ruptured blood vessel.
hemorrhagic stroke
Name the 4 main lobes of the brain.
frontal, parietal, temporal, occipital
Signs such as high fever, stiff neck, and intense headache may indicate this inflammation of the meninges.
meningitis
This lowest part of the brainstem contains cardiac, respiratory, and vasomotor centers.
medulla oblongata
Type of amnesia where a person cannot recall things known before an injury
Retrograde amnesia
This sleep disorder is caused by low levels of orexins (hypocretin) in the hypothalamus.
narcolepsy
Name the three meninges of the brain.
Pia mater, arachnoid mater, dura mater.
This structure produces most CSF and is found in each ventricle.
choroid plexus
This lobe of the cerebrum is responsible for planning, decision-making, and voluntary motor control.
frontal lobe
This language area formulates speech and sends the plan to Broca’s area.
Wernicke's area
This condition is caused by failure of the cerebral cortex to show detectable brain waves.
brain death
These three brain regions—the thalamus, hypothalamus, and epithalamus—make up this major part of the forebrain.
Diencephalon
These cauliflower-like projections reabsorb CSF into the venous circulation.
arachnoid granulation
This network of gray matter through the brainstem controls sleep, consciousness, pain modulation, and posture.
reticular formation
Type of brain waves seen on EEG when a person is awake and under emotional stress or in drowsy/sleeping adults. (4-7 Hz)
theta waves
Degeneration of the substantia nigra leads to tremors characteristic of this disease.
Parkinson's disease
