4 main regions of brain
separates the parietal and frontal lobes
central sulcus
"little brain"
cerebellum
involved in balance and coordination, muscles toning, driving, typing, instrument playing
cerebellum
divided into left and right hemispheres by *longitudinal fissure*
cerebrum
largest part of the brain
cerebrum
folds that increase the SA of the cerebral cortex
gyri
below thalamus
hypothalamus
maintains homeostasis; regulates: body temp, hunger, thirst, sexual plessure, feeling good after meal, rage, fear, also inappropriate emotions such as nervous sweat and eating when depressed
hypothalamus
has and infundibulum that does what
hypothalamus has a infundibulum that is a funnel shaped structure that connects the pituitary gland to the hypothalamus
has mammilary bodies that do what
hypothalamus has mammilary bodies that are involved in emotional responses to odors and memory
auditory pathways to CNS-involved in the startle reflex-auditory reflex center (2 of these)
inferior colliculi
most inferior region of the brain
medulla oblongata
regulates heart rate, swallowing, sneezing, blood pressure, vomiting, balance, breathing, coughing, coordination
medulla oblongata
vital center
medulla oblongata
parts of the brain stem
medulla oblongata, pons, midbrain, reticular formation
immediately superior to the pons
midbrain
lobe that functions in reception and perception of visual input
occipital
lobe that functions in reception and perception of most sensory info( touch pain temp balance taste)
parietal
"bridge"
pons
controls breathing, swallowing, balance, chewing, and salivation
pons
immediately superior to the medulla oblongata
pons
relays info bw the cerebrum and cerebellum
pons
connects the spinal cord to the brain
brainstem
four main regions of brain
brainstem, diencephalon, cerebrum, cerebellum
what inhibits the cerebellum
alcohol
what happens if the reticular formation is damaged
coma
how is the cerebellum a comparator?
compares brains intentions with bodys performance
damage to the brain stem results in...
death
bw the brainstem and cerebrum
diencephalon
has small nuclei that are involved in emotional and visceral responses to odors
epithalamus
posterior to the thalamus
epithalamus
contains the pineal body that does what
epithalamus has a pineal body that is a gland that secretes hormones and is involved in setting your biological clock and the onset of puberty
lobe that functions in voluntary motor functions, motivation, aggression, ood, and smell reception
frontal
separates the temporal from the cerebrum
lateral fissure
2 prominent enlargements on the medulla oblongata that send action potentials from the brain to the motor neurons to control skeletal muscle movements
pyramids
group of cell bodies scattered throughout the brainstem
reticular formation
regulates cyclical motor functions (respiration, walking, chewing) maintaining consciousness & regulates sleep cycle
reticular formation
the grooves (lines bw bumps)
sulci
involved in visual reflexes- coordinate head and eye movements when we usually are following an object, even if we are not consciously looking at the object-visual reflex center
superior colliculi
lobe that functions in olfactory (smell) and auditory role in memory, abstract thought and judgement
temporal
largest part of the diencephalon- looks like a yo-yo
thalamus
relay of sensory input to the cerebrum; also influences mood and registers an unlocalized, uncomfortable perception of pain
thalamus
parts of the diencephalon
thalamus, epithalamus, hypothalamus,
