Physio and Psycho Flashcards
(263 cards)
Medulla Function
Mouth and throat movements, respiration, hr, bp, injury = death
Pons
connects halves of cerebellum, relays info for movement, deep sleep, respiration, REM
Cerebellum
posture, balance, voluntary movements, procedure and implicit memories
attention, language and visual
what does damage to the cerebellum cause
ataxia (symptoms of intoxication)
Reticular Formation
coordination of eye movements and pain control
The RAS is part of what brain region and what does it do?
Reticular formation; mediates consciousness/ arousal, sleep wake and alerts to sensory signals
what is the reward seeking part of the brain and what else does it do
the substantia nigra, has motor control via the basal ganglia
degeneration of dopamine producing cells in the substantia nigra can cause
parkinson like symptoms
studies used electrical stimulation to show the contribution of what brain part to emotions
hypothalamus
the hypothalamus produces mammilary bodies, what is their role
memory and SCN (bodies bio clock)
what does GnRh do
regulates functions of the testes/ ovaries
what is the difference between oxytocin and vasopressin in the posterior pituitary
oxytocin: contractions and lactation, vasopressin: water balance via kidneys
what mental health disorders can Oxytocin help with
ASD, schizophrenia, disorders that involve deficits in recognition of emotions and facial expressions
which brain function is responsible for transmitting all sensory info, coordination of sensory/motor functioning, language, speech and declarative memory
Thalamus (relay station)
which condition is due to thiamine deficiency and how does that effect it
Korsakoff is due to thiamine deficiency that damages neuron’s in thalamus and mammillary bodies.
What is included in the stratum and what is it a part of
the stratum is part of the basic ganglia and has the caudate nucleus, putamen and nucleus accumbent to receive info from the cerebral but the globes pallid us transmits info to thalamus
what function does the basal ganglia have
initiation and control of voluntary movements, procedural and habit learning, cog functioning and emotions
mood disorders, schizo, adhd, ocd, Huntington’s and Parkinson’s have been related to damage in which area
basal ganglia
What is the role of the amygdala
fear, acquisition of conditioned fear, evaluation of emotional significance of events, recognizing emotions in facial expressions
how is PTSD related to the amygdala
associated with abnormal functioning and hyperactivity in the amygdale which produces distressing memories however hyperactivity of VPC can reduce normal regulation of activity
What is kluver-bucy syndrome
bilateral legions on amygdala, hippocampus and temporal lobes in monkeys led to hyperreality, reduced fear, hyper sexuality, blindness
The ___ is linked to motivation, memory and emotions to pain. Damage people can experience pain but cant____
cingulate cortex and not be emotionally distressed by the pain
Which brain region transfers declarative memories from short - long term
Hippocampus
damage in what cells and what cortex lead to impairments in episodic and spatial memory that is liked to Alzheimer’s
hippocampus cells and the entorhinal cortex (gateway for information entering and leaving the hippocampus
