Ch 15 Lec 3 - Human Brain Flashcards
part of the mesencephalon that has the superior and inferior colliculi
corpora quadrigemina
receives visual input from thalamus in corpora quadrigemina
superior colliculi
receives auditory input from medulla in the corpora quadrigemina
inferior colliculi
rounded bulge on the underside of the brain stem
pons
pons separates blank from blank
midbrain, medulla
the pons is made of masses of blank matter and blank fibers
gray, nerve
pons blank impulses to and from blank and blank
relays, medulla, cerebrum
pons regulates blank
depth of breathing
this has two hemispheres and is below the cerebrum
cerebellum
two hemispheres of cerebellum are separated by blank and connected by blank
falx cerebelli, vermis
the cerebellum is mainly blank matter and is controlled by the blank
white, arbor vitae
cerebellum integrates blank information about the blank of body parts
sensory, position
cerebellum coordinates blank activities
muscle
cerebellum fine tunes blank and blank movements
voluntary, involuntary
this is a point of connection for several cranial nerves and goes from the foramen magnum to the pons
medulla oblongata
oval swellings of medulla oblongata
olivary nucleus
two reflex centers of the medulla oblongata
cardiovascular center, respiratory rhythmicity center
reflex center of medulla that adjusts blood flow and heart rate
cardiovascular center
reflex center for basic pace of respiratory movements in medulla
respiratory rhythmicity center
network of nerve fibers associated with islands of gray matter
reticular formation
reticular formation blank areas with fibers in all major tracts
interconnects
reticular formation regulates these motor activities
sleep, wakefullness
inc activity means
wakefulnesss
dec activity means
sleep
nuclei and tracts along the border of cerebrum and diencephalon
limbic system
three parts of cerebrum are part of the limbic system
limbic lobe, hippocampus, amygdaloid body
deep to all other lobes and is part of limbic system
limbic lobe
nucleus within limbic lobe
hippocampus
the limbic system establishes blank states and related blank drives
emotional, behavioral
limbic system links intellectual functions of blank to unconscious functions of blank brain
cortex, lower
the limbic system facilitates blank storage
memory
there are 12 blank nerves
cranial
all cranial nerves originate from the blank except the first pair
brain stem
cranial nerve for smell and passes through the blank
olfactory, cribriform plate
cranial nerve for vision and passes through the optic blank
vision, foramina
cranial nerve that moves the majority of eye muscles
oculomotor
cranial nerve that is the smallest pair and controls superior oblique muscles of eye only
trochlear
cranial nerve that is the largest and has three branches that controls face, pallet, eye, teeth
trigeminal
cranial nerve that controls the lateral rectus eye muscles only and comes from pons
abducens
cranial nerve that comes from pons and has taste receptors on tongue and has muscles for facial expression
facial
cranial nerve that comes from the auditory nerve from the medulla and has two parts that is sensitive to position of head and is interpreted as hearing
vestibulocochlear
cranial nerve that helps swallowing
glossopharyngeal
cranial nerve that is from medulla to chest and abdomen and is for speech and swallowing and controls the heart, lungs, esophagus (viscerals)
vagus
cranial nerve with two branches that controls musculature of throat
accessory
cranial nerve that also controls tongue and neck musculature and near chin
hypoglossal
