Dicephalon thalamus, hypothalamus, pituitary gland
Thalamus relay station between cerebral cortex &
brainstem
-auditory, somatosensory, visual,
gustatory,
signals
-influences arousal & wakefulness
Hypothalamus Controls hormone release in pituitary gland
-controls temperature, BP, hunger, thirst,
sexual
behavior, circadian rhythm
Pituitary Gland "Master gland"
directs other organs and endocrine glands
to
adjust hormone production
Anterior Pituitary Gland Hormone release: BP, metabolism,
gluconeogenesis, lactation, ovulation,
growth and
immune supression
Posterior Pituitary Gland Hormone release: labor, birth lactation,
and BP
,Basal Ganglia Controls voluntary movement &
coordination
-located near thalamus
- gray matter, contains caudate nucleus,
lenticular
nucleus
-connection between PMC and brainstem
Brainstem structures midbrain, pons, medulla
Midbrain -Controls vision, hearing, motor control,
sleep/wake, arousal, temp
-motor+sensory tracts pass through
-red nucle, substantia nigra (CN III & IV)
Pons Controls sleep, Resp drive, swallowing,
balance,
bladder control, taste, eye movement,
facial
expressions, sensation
-CN V, VI, VII, VIII
-motor/sensory tracks, communication
between
cerebrum & cerebellum
-Reticular formation: consciousness
Medulla Oblongata Controls RR, HR, digestion- vomitting
sneezing,
swallow, balance
-CN IX, X, XIII
, Cerebellum "Little brain"
Controls coordination & balance
-contributes to cognitive function &
language (not
well understood why)
-talks to pons & spinal cord
Homunculus diagram that depicts what body parts are
controlled by the motor/sensory strips
Frontal Lobe thinking, planning, organizing,
problem-solving,
short term memory,
deficits: change in behavior, lack
judgement,
difficulty reasoning and paying attention,
difficulty
organizing
Parietal Lobe sensory info- taste, texture, temperature
deficits: sensory impairments (tactile
agnosia),
visuospatial difficulties (loss of
proprioception),
and problems with motor control and
planning
Occipital Lobe processing, recognizing, connecting
information
deficits: field cut, difficulty with object
recognition
(visual agnosia), vision changes,
Akinetopsia
(inability to ID motion)
