control center for body fxns
brain
part of PNS; arise directly from brain
cranial nerves
major regions of the brain
brainstem, cerebellum, cerebrum, diencephalon
parts of the brainstem?
medulla oblongata, pons, midbrain
parts of the diencephalon?
thalamus, subthalamus, hypothalamus–pituitary gland, epithalamus–pineal gland
parts of the cerebrum?
hemispheres, basal ganglia, limbic system
vital nuclei of the medulla oblongata?
cardiac center, respiratory center
fxns of pyramids in medulla oblongata?
motor tracts for skeletal mm
fxns of olives in medulla oblongata?
balance & coordination, sound modulation
keeps brain alert and awake; loosely organized web of gray matter
reticular formation
relay center between cerebrum and cerebellum
pons
connection points
peduncles
the pons is the ______ center
sleep
aka mesencephalon
midbrain
tectum
roof
corpora quadrigemina consists of
superior colliculi (visual) and inferior colliculi (hearing)
descending nerve tracts
cerebral peduncles
ascending nerve tracts are located
tegmentum
unconscious regulation & coordination of motor activities
red nucleus
inhibitory motor center; degenerates in Parkinson disease; produce lots of dopamine
substantia nigra
fxns: somatic motor control, cardiovascular control, pain modulation, sleep & consciousness, habituation
reticular formation
when reticular formation doesn’t work and you fall asleep randomly
narcolepsy
BIG JOB of cerebellum
coordination of skeletal muscle contraction
folds of cerebellum
folia
