frontal
The innermost layer of the meninges, delicate and closely apposed to the brain tissue, is the?
pia mater
Cerebrospinal fluid is formed by the?
choroid plexus
A patient has suffered a cerebral hemorrhage that has caused dysfunction of the precentral gyrus of his right cerebral cortex. as a result,
he cannot voluntarily move his left arm or leg
Basal nuclei involved in fine control of motor activities is called
striatum
The region where there is a gross crossover of fibers of descending pyramidal effects
medulla
Controls temperature, autonomic nervous system reflexes, hunger and water balances
hypothalamus
Houses the substantia nigra and the cerebral aqueduct
midbrain
Relay stations for visual and auditory input, found in midbrain
corpora quadrigemina
Houses vital centers for control of the heart, respiration, and blood pressure
medulla
Brain area through which all the sensory input is relayed to get to the cerebral cortex
thalamus
Brain area most concerned with equilibrium, body posture, and coordination of motor activity
cerebellum
Which tracks convey vibration and other specific sensations that can be precisely localized
medial lemniscus
Destruction in the ventral horn cells of the spinal cord results in loss of
voluntary muscle impulses
Fiber tracts that allow neurons within the same cerebral hemisphere to communicate are
association tracts
Cerebral cortex is made up of
grey matter
Corpus callosum and corona radiate are made up of
white matter
Red nucleus are made up of
grey matter
mMedial and lateral nuclear groups are made up of
grey matter
Medial leminiscal tract is made up of
white matter
Cranial nerve nuclei is made up of
grey matter
Spinothalamic tract is made up of
white mater
Fornix is made up of
white matter
Cingulate and precentral gyri are made up of
grey matter
Reflex movements of the eyes are mediated by the
superior colliculi
The stage where blood pressure and heart rate reach their lowest
stage 4
Stage of sleep indicated by movements of eyes under lids, dreaming occurs
REM
Stage of sleep when nightmares are likely to occur
stage 3 and 4
Stage of sleep when the sleeper is easily awakened. EEG shows alpha waves
stage 1

include gracilis and fasciculus cuneatus. include a chai of three neurons. they are concerned with precise transmission of one or a few related sensory modalites
