frontal lobe
which structures are NOT apart of brain
cerebral hemispheres, cerebellum, diecephalon
gyrus
an elevated ridge of cerebral tissue
surface area
convolusions seen in cerebrum increase these
neuron cell bodies
gray matter is composed of these
myelinated fibers
white matter is composed of these
association tract
fiber tract that provides for communication between different parts of the same cerebral hemispheres
projection
fiber tract that carries impulses to the cerebrum, and from the cerebrum to lower CNS areas
basal nuclei
lentiform nucleus along with the caudate nuclei are collectively called this
hypothalamus
site of regulation of body temp and water balance, most important autonomic center
cerebral hemisphere
consciousness depends on the function of this part of the brain
corpora quadrigemina
located in the midbrain, contains reflex centers for vision and audition
cerebellum
responsible for regulation of posture and coordination of complex muscular movements
thalamus
important synapse site for afferent fibers traveling to sensory cortex
medulla oblongata
contains autonomic centers regulating blood pressure, heart rate, and respiratory rhythm, as well as coughing, sneezing, and swallowing centers
corpus callosum
large commissure connecting the cerebral hemispheres
fornix
fiber tract involved with olfaction
cerebral aqueduct
connects the third and fourth ventricles
thalamus
encloses the third ventricle
forebrain
diencephalon, including thalamus, optic chiasma, hypothalamus
hindbrain
medulla, pons, cerebellum
forebrain
cerebral hemispheres
basal ganglia
involved in regulation, modulation, refinement of voluntary motor activity
corpus striatum
fibers of the internal capsule pass between basal nuclei, giving them a striped appearance, striped body
split brain
when corpus callosum cut
