|
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 |
