brain pt2 (inside) Flashcards
centrally located within the brain sitting at the top of the brain stem above the midbrain and under the cerebrum
diencephalon
diencephalon is comprised of the
epithalamus, thalamus, and hypothalamus
right and left thalamus are connected by the
massa intermedia (interthalamic adhesion)
hollow stalk which connects the hypothalamus and pituitary gland
infundibulum
regulates growth, metabolism, and reproduction through the hormones that it produces
pituitary gland
where optic nerves go into brain
optic chiasm
pair of small round bodies, located on the undersurface of the brain
mammillary bodies
below the cerebral cortex and at the topmost part of the brainstem. has two colliculi and one peduncle
midbrain
hangs posterior to the thalamus. releases melatonin and controls sleep cycles
pineal gland
large, C-shaped nerve fiber bundle (white matter) found beneath the cerebral cortex. Connects left and right hemispheres
corpus callosum
white matter bundle right beneath lateral ventricles
fornix
C-shaped cavity located deep within cerebrum. sandwiched by corpus callosum and fornix
lateral ventricles
a cavity of hindbrain connected to the third ventricle by a narrow cerebral aqueduct
fourth ventricles
a fluid-filled canal that runs through the midbrain connecting the third and fourth ventricles
cerebral aqueduct
links your brain to your spinal cord (medulla oblongata). inferior to midbrain
pons
base of brain stem connecting to spinal cord
medulla oblongata
two bulges of gray matter stacked at midbrain
superior colliculus and inferior colliculus
small folds of cerebellum
folia
white matter shaped as a tree in cerebellum aka tree of life
arbor vitae
connective tissue layers of membranes below skull bones serving to protect brain
meninges
largest, most superior located chambers in brain
lateral ventricles
meets with bottom of lateral ventricles by the interventricular foramen
third ventricle
attaches to third ventricle by the cerebral aquaduct
fourth ventricle
joins lateral ventricles and third ventricle
interventricular foramen
joins third and fourth ventricle
cerebral aqueduct
number of cranial nerves
12 pairs
mnemonic for remembering which nerve pairs are for sensory, motor, or both (12 pairs)

region of brain responsible for taste
gustatory cortex
