Test 2 Pathologies

Question 0

Huntington’s chorea

Answer 0

Produce too much dopamine so movements are spastic and can’t stop= flailing movements

Question 1

Parkinson’s

Answer 1

Problems in the basal nuclei control
Effects the neurons of basal ganglia which steady movements normally; neurons can’t make dopamine correctly so movements events aren’t stabilized and you shake

Question 2

emotion induced illness

Answer 2

psychosomatic

Question 3

schizophrenia

Answer 3

really high dopamine levels

treated with dopamine receptor blockers

Question 4

depression

Answer 4

too little norepineprine, serotonin or both

Question 5

hydocephaly

Answer 5

water on the brain
pressure builds up and can damage neurons
caused by the CSF being unable to drain into the blood sinus between the sub layers of the dura mater

Question 6

neuritis

Answer 6

inflammation of neurons

Question 7

neuralgia

Answer 7

pain due to inflamed neurons

Question 8

sciatica

Answer 8

neuralgia of sciatic nerve

Question 9

shingles

Answer 9

due to dormant chicken pox virus traveling from the dorsal root ganglia to a dermatome and stimulating that area to feel pain

Question 10

cerebral palsy

Answer 10

damage to motor parts of the brain
caused by oxygen deprivation
efferent motor part damaged

Question 11

neuroma

Answer 11

neural cell tumor

Question 12

glioma

Answer 12

glial cell tumor

keeps glial cell from being able to protect the nervous system so it can be damaged

Question 13

stroke (cerebral vascular accident)

Answer 13

brain loses oxygen due to blockage of vessel of rupture
most common brain disorder
3rd leading cause of death in the US

Question 14

TIA

Answer 14

transient ischemia attack

=reduced blood flow

Question 15

seizure disorder

Answer 15

2nd most common brain disorder

sudden burst of uncontrolled neural activity causes jerky movements and unconsciousness

Question 16

meningitis

Answer 16

inflammation of the meninges (bacterial)
causes stick neck, fever, and seizure
20% fatal

Question 17

encephalitus

Answer 17

inflammation of brain tissue (viral)

very high mortality rate

Question 18

Alzheimer’s disease

Answer 18

irreversible loss of neurons due to buildup of plaques that cause neuronal cell death
1st impacts transmission of signals in memory centers
