47 Cards in this Set

  • Front
  • Back
cerebral cortex
thought, voluntary movement, language, reasoning, perception
movement, balance, posture
brain stem
breathing, heart rate, blood pressure
body temp, emotions, hunger, thirts, circadiam rythms
sensory processing, movement
vision, audition,eye movement, body movement
4 lobes of brain
frontal lobe
reasoning, planning, part of speech/movement, emotions, problems solving
parietal lobe
perception of stimuli related to touch, pressure, temp, pain
temporal lobe
perception and recognition of auditory stimuli and memory
occipital lobe
aspects of vision
functions of left side of brain
language, math, logic
functions of right side of brain
spatial abilities, face recognition, visual imagery, music
7 things that can break down blood brain barrier
hypertension (high BP)
development - not fully formed
hyperosmolity - hight conc. of substance in blood
trauma, inflamation, pressure
which part of the brain has been found to grow neurons?
the hippocampus
what are primary afferent axons?
nerve fibers connected to different receptors in skin, muscles, and internal organs. info about pain and touch are transmited
how are primary afferent axons divided into groups?
by size
which primary neuron travels fastest? the slowest? why
a-alpha = fastest
c= slower
why, the thiker ones travel faster
why when you stub your toe you feel the pain a few seconds after you hurt it?
b/c pain travels in C neuron so it is slower to travel then the a-alpha neuron that carries touch
central nervous system includes...
brain and spinal cord
alcholo is a CNS
peripheral nervous system
motor neurons and sensory neurons
motor neuron
recieve info from motor CNS for motor movement
sensory neuron
send info to CNS (environment)
brain protection
cerebrospinal fluid
spine protection
cerebrospinal fluid
cerobrospinal fluid - buffers brain
2.buoyancy - pressure at base of brain is reduced cause its floating
3.gets rid of waste product from brain
4.endocrine medium 4 brain - transport hormones 2 other part of brain
what is alzheimers?
destroys brain cells
what caues AD?
abnormal structures - amyloid plaques and neurofibriallary tangles
amyloid plaques
clumps of altered proteins that form outside cells in brain
neurofibrillary tangles
clumps of altered proteins that from inside brain
risk factors for AD
1. age (65+ 10%)(85+ 50)
3.high cholesteral, high BP
memory loss, difficulty preforming familliar tasks, probs with language, disoreinattion wiht time and place, poor/decreased judgement, problems with abstract thinking, misplacing things, changes in mood/behavior, changes in personality, loss of initiative
treatment for AD
no cure but can improve/stabalize symptoms
2.vitamin E -help brain cells defend from attack
what is MS
autoimmune disease, affects CNS
what happens in MS?
myelin is lost, leaving scar tissue called sclerosisn (lesions/plaques)
type of MS
relasping-remitting 85%
causes of MS
1.immunologic -immune system attacks mylin tissue
2.genetics - determine if person with be susceptable to triggering factor
3.environmental - some agent exposed before puberty
4.viral - long latency period
average persons chance of getting MS in US
average chance of person with relative with MS
identical twin average
patterns of MS
1. ages 20-50
2.2-3 times more often in women
3.more often in whites
4.250,000-350,000 in US
5. higher chance at higher latitude (40)
treatment for ms
2.drugs that block immune system from attack on myelin
3.medicnes to reduce pain/inflamation
4.physical therapy
what is PD?
disorder of CNS - progressive loss of motor movement
loss of dopamine (60-80% of normal person)
what causes PD?
the cause is unknown
environmental trigger/genetic factors
age (50+)
signs/symptoms of PD
tremors, difficulty walking,rigidy, poor palance, slowness of movement, difficulty speaking
treatments of PD
1.levodopa - changed to dopamine - dont wnat to become dependent
2.indirect acting dopamine agonist - block or increase amount of dopamine taken by cells
3.dopamine agonists-act on dopamine receptors directly
