Exam 4 review Flashcards
parts of Diencephalon
Thalamus, Pineal body, Pituitary Gland and Hypothalamus
When studying a new language this portion of the brain is + (motor control/ highly practiced learned behavior through repetition)
Basal nuclei
Characteristics of Basal Nuclei
Includes the corpus striatum (“striped body”), made up of the caudate nucleus (“tail”), the putamen (“shell”), the globus pallidus (“pale globe”), and the nucleus accumbens (“leaning”)
Parts of the brainstem
Diencephalon/ midbrain/ pens/ medula oblongata
pons fxn
sits directly above the medulla, connects upper and lower parts of brain and articulates CN 5-8
CN stem from what part of the brain?
CN1-3 peduncle 4? 5-8 Pons 9-12 medulla
vegas nerve affect on heart rate
psns affect on heart (lower HR). when not + will ^ HR
sinuses and brain function
look it up
hypothalamus fxn
part of diencephalon and limbic system and helps control autonomic nervous and homeostasis fxns. e.g.; body temp, hormones, sleep/wake cycle, hunger
thalamus fxn
the relay station for all sensory info, also part of diencephalon
difference between the blood brain barrier and the blood CSF barrier
look it up
how the limbic system affect Ulric
specifically the hypothalamus and its connection to the pituitary gland, but also the amygdala but limited with the hippocampus
Motor homunculus relates to which gyrus
post central gyrus
sensory homunculus relate to which gyrus
pre central gyrus / prefrontal cortex involved in thinking about the future, making plans, and taking action, and plays a part in pleasure and addiction.
path of CSF
steps 1-8 look ‘em up
Pineal Body
resets circadian rhythm, part of diencephalon and associated with reticular formation
Pituitary gland
part of diencephalon helps control hormones
Amygdala’s affect on Katharos and Ulric
when overly stimulated (K) increases aggression when under-stimulated (U) tame, indefferent to fear or sexual responses
Hippocampus affect on my story telling
turns short-term memory into longterm memory. helps create stories while sleeping
Caudate nucleus
sends info to frontal lobe and responsible for informing us that something is not right and we should do something about it: Wash your hands! Lock your door! (+++ = OCD/ — = ADHD/ depression/ a lil schizo and low motivation)
putamen
involved in coordinating automatic behaviors such as riding a bike, driving a car, walking.
globus pallidus
It receives inputs from the caudate and putamen and provides outputs to the substantia nigra
nucleus accumbens
It receives signals from the prefrontal cortex
substantia nigra
dopamine, melanin, GABA and eyemovement
