UTMB 5355 PATHOPHYSIOLOGY EXAM QUESTIONS
AND ACCURATE ANSWERS LATEST VERSION
According to the Biogenic Amine Theory, depression is caused by a lack of
norepinephrine, dopamine, and/or serotonin neurotransmitters in the brain.
Specifically, a reduction in serotonin receptor binding.
ANSWER A shortage of monoamine neurotransmitters at neural synapses is the
neurotransmitter receptor hypothesis that has been connected to depression.
Antidepressants raise monoamine neurotransmitter levels at the synapses of
neurones.
ANSWER Neurotransmitters do not have enough time to re-charge if you have
more receptors than neurotransmitters. As a result, they do not work as
intended.
A significant portion of individuals with serious depression have hypothalamic-
pituitary-adrenal (HPA) system dysregulation, which manifests as increased
glucocorticoid secretion.
Alzheimer's disease pathogenesis includes the development of plaque, the
presence of --, and decreasing levels of ANSWER Amyloid B, neurofibrillary
tangles, and acetylcholine, all of which interfere with impulse transmission.
ANSWER neurofibrillary tangles are a distortion of the structure that supplies
the brain's neurones with nutrition.
ANSWER Memory loss is linked to decreased amounts of choline acetyl
transferase and acetylcholine.
The most prevalent cause of dementia is ANSWER Alzheimer's disease, which
kills people 5–10 years ago.
Alzheimer's symptoms include: ANSWER Memory loss, language impairment,
learning disabilities, dysfunction, delusions, incapacity to perform ADLs, and a
significant impact on social life
Parkinson's disease, also referred to as shaking palsy, is a chronic motor
progressing neurodegenerative condition.
, Parkinson's disease is linked to atrophy of dopamine-producing neurones in the
substantia nigra and malfunction of the ANSWER basal ganglia;
Parkinson's disease symptoms include bradykinesia, muscle rigidity, postural
problems, and resting tremors.
There are two primary types of CVA: hemorrhagic and ischaemic.
Hemorrhagic CVA: ANSWER Blood causes oedema, inflammation, brain
tissue displacement, and elevated intracranial pressure.
There are two types of hemorrhagic stroke: subarachnoid and intracerebral.
ANSWER: Intracerebral haemorrhage occurs when a blood artery bursts into
brain tissue.
Subarachnoid haemorrhage: ANSWER The "worst headache of life" is a
symptom of bleeding into the subarachnoid space brought on by trauma or
aneurysm rupture. emergency surgery
Reduced cerebral blood flow from an ischaemic cerebrovascular accident causes
hypoxia, irreversible cell death, and related cerebral oedema.
ANSWER thrombotic, embolic, and hypercoagulable states are the three forms
of ischaemic CVA.
Thrombotic: ANSWER brought on by artery-blocking atherosclerosis. blood
artery blockage brought caused by a localised occlusive process
Embolic: an answer brought on by a blood clot, fat, or air embolus that travels
from a far-off location to the brain
ANSWER disorders like sickle cell disease and polycythaemia that cause blood
clots to form and clog vessels are examples of hypercoagulable states.
An ANSWER chronic, inflammatory, autoimmune demyelinating disease of the
central nervous system is multiple sclerosis. Patho involves CNS demyelination,
which is believed to be brought on by an immunological response.
Acetylcholine is an ANSWER excitatory or inhibitory neurotransmitter that
facilitates learning, memory, and muscle movement. It is implicated in
Alzheimer's disease memory impairment.
