Ch 15 Lec 1 - Human Brain Flashcards
regions of the brain
cerebrum, diencephalon, mesencephalon, cerebellum, pons, medulla oblongata
unconscious coordination of the brain
cerebellum
region of brain that controls rhythms and sleep patterns
pons
region of the brain that regulates cardio function, respiratory function, digestive function
medulla oblongata
the brain has blank similar to spinal cord
meninges
outer most layer of the brain and forms the internal blank of the skull
dura mater, periosteum
there is no blank in the meninges of the brain
epidura
partitions of the dura mater in the brain
falx cerebelli, falx cerebri, tentorium cerebelli
dura mater partition that separates right and left cerebellar hemispheres
falx cerebelli
dura mater partition that separates right and left cerebral hemispheres
falx cerebri
dura mater partition that separates lobes of cerebrum from cerebellum
tentorium cerebelli
has a blank and blank mater like spinal cord
pia, arachnoid
ventricles of the brain are spaces filled with blank
csf
there are two blank ventricles of the brain
lateral
2 lateral ventricles of brain are connected to the third ventricle by blank
interventricular foramen
the blank ventricle of the brain is connected to the fourth ventricle by the blank
third, central canal
the blank ventricle connected to central canal of the blank
fourth, spinal cord
three functions of cerebrospinal fluid
cushions, transport nutrients, transport wastes, supports brain
csf comes from blank
the brain
csf is formed in blank in the brain
choroid plexus
lobes located in the ventricles of the brain that consist of ependymal cells and permeable capillaries
choroid plexus
csf is taken from the blank by blank cells and pooled in the ventricles
blood, ependymal
csf moves throughout the entire blank
central nervous system
csf moves through blank in the fourth ventricles to blank space
apertures, subarachnoid space
csf is around the blank
subarachnoid space
csf is reabsorbed in the blank
sagittal sinus
large venous tube within the dura mater
sagittal sinus
sagittal sinus extends along the midline of the blank
cerebral hemispheres
arachnoid extends into sagittal sinus through blank
arachnoid granulation
in the sagittal sinus, csf goes back to blank
the blood
three functions of cerebrum
interpret sensory impulses, voluntary muscle movements, memory, reasoning process, intelligence, personality
cerebrum has two blank
hemispheres
two hemispheres of cerebrum are connected by blank
corpus callosum
two hemispheres of brain are separated by blank
longitudinal fissure
two hemispheres possess ridges (blank) and grooves (blank)
gyri, sulci
hemispheres of cerebrum receives blank and generates blank information to the blank side of the body
sensory, motor, opposite
hemispheres of cerebrum communicate by the blank
corpus callosum
cell somas of the cerebrum are located at outer regions of cerebral blank
lobes
cell somas of cerebrum are centralized in masses called blank
basal nuclei
cell somas are blank matter
gray
myelinated axons are blank matter
white
three types of cerebral white matter
commissural fibers, association fibers, projection fibers
cerebral white matter that connect corresponding gray areas on different hemispheres
commissural fibers
cerebral white matter that connect different parts of same hemisphere
association fibers
cerebral white matter that connect cerebrum to lower brain areas
projection fibers
these are named after the bone they are found under
cerebral lobes
four lobes of cerebrum
parietal, frontal, temporal, occipital
one cerebral lobe is blank
deep
the deep cerebral lobe
insula
cerebral lobes are separated by special blank
sulci
three sulci of cerebrum
central, lateral, parieto-occipital
cerebral sulcus that separates the frontal lobe from the parietal lobe
central sulcus
cerebral sulcus that separates the parietal lobe from the temporal and is the most obvious
lateral sulcus
cerebral sulcus that separates the parietal lobe from the occipital
parieto-occipital sulcus
region of the cerebrum that deals with conscious motor control of skeletal muscle
primary motor cortex
primary motor cortex is blank to central sulcus in the frontal lobe
anterior
speech, eye movements, and learned motor skills are driven by this cerebral region
primary motor cortex
primary motor cortex is in the blank lobe
frontal
this cerebral region is posterior to central sulcus and is in the parietal lobe
primary sensory cortex
primary sensory cortex deals with somatic blank information of touch, pain, pressure
sensory
this cerebral allows you to monitor the environment consciously
primary sensory cortex
