41 Cards in this Set

  • Front
  • Back
metencephalon
pons + cerebellum
Forebrain
Prosencephalon; consists of telencephalon plus diencephalon
Diel the telephone
Telencephalon
cerebrum
occipital lobe
visual and association areas
cerebrum constituents
two cerebral hemispheres
gray/white matter divided into
5 cerebral lobes and
basal ganglia group
five cerebral lobes
frontal parietal temporal occipital insular
frontal lobe
motor and premotor areas
precentral gyrus
parietal lobe
sensory and association areas
postcentral gyrus
temporal lobe
auditory areas
central sulcus
divides the frontal and parietal lobes
cerebellum lobes
anterior, posterior, flocconodular
basal ganglia constituents
caudate nucleus
putamen
globus pallidus
substantia nigra
subthalamic nucleus
lateral fissure
like a sulcus; divides the temporal lobe from the frontal and parietal lobes
cerebellum fissures
primary, posterolateral
insular lobe
deep to the lateral fissure
Cavities of the brain
Ventricles; two laterals, 3rd and 4th.
parietooccipital sulcus
seperates the occipital lobe from the parietal lobe; can't see it very well just by looking at the back of the brain, but if you were to take a blade and drive it in it would make the division that can be seen from a medial view
calcarine fissure
bisects the occipital lobe; like shoving something in horizontally
major gyri of the cerebrum
pre/post central gyri
temporal gyri (superior/middle/inferior)
cingulate gyrus
parahippocampal
diencephalon constituents
thalamus
hypothalamus

part of forebrain along with telenceph.
thalamus
major relay center for sensory functions, except olfaction

upper diencephalon
hypothalamus
maintainence of homeostasis/equilibrium and motivated behaviors; functions in concert w/ autonomic, endocrine systems.
Located near mamillary bodies, pineal gland; connection of infundibulum
mesencephalon
midbrain
midbrain constituents
connects the telencephalon to hindbrain;
the MID is a MESSencephalon of stuff:
cerebral peduncles
substantia niagra, red nucleus
origin of CN III and IV
mesencephalic central grey
tectum: superior/inferior colliculi (corpora quadrigemina)
hindbrain
RHOMBENCEPHALON
pons, cerebellum, (aka metencephalon) + medulla oblongata (aka myelencephalon)
central canal
cavity of the spinal cord
central canal
cavity of the spinal cord
midbrain constituents
connects the telencephalon to hindbrain;
the MID is a MESSencephalon of stuff:
cerebral peduncles
substantia niagra, red nucleus
origin of CN III and IV
mesencephalic central grey
tectum: superior/inferior colliculi (corpora quadrigemina)
pons
origin and conduit of numerous fiber tacts which ascend, descend, or enter cerebellum; origin of CN V-VII
Cerebellum
little brain
coordinates motor activity by processing proprioceptive info from muscles tendons and joints.
Cerebellum folds
folia
cerebellar peduncles
superior/middle/inferior; on the cerebellum, connect it to the pons/medulla oblongata
choroid plexus
highly vascularized connective tissue covered w/ ependymal layer; within the lateral ventricles and the roof of the 3rd/4th ventricles; produces CSF in the ventricular system.
lateral ventricles
the cavity within the the telencephalon. extend to all the lobes because they consist of anterior/posterior, and inferior horns.
interventricular foramen of Monro
the duct between the lateral ventricals and the third ventricle
myelencephalon
medulla oblongata; contains origin cells of numerous fiber tracts; sensory relay nuclei like nucleus cuneatus and gracilus, and CN IX-XII origins; also, pyramids and decussation; reticular formation and associated projection systems
Brain stem
medulla oblongata + pons + midbrain
Third ventricle
the cavity within the diencephalon; connects to the fourth by the cerebral aqueduct
cerebral aqueduct of Sylvius
the cavity of the mesencephalon; connects the 3/4 ventricles
4th ventricle
the cavity within the metencephalon and myelencephalon. (very thin) continuous with the central canal
foramen of Magendie/Luschka
1 magendie
2 lushka
foramen in the fourth ventricle allowing cerebrospinal fluid to bathe the outer spinal cord
