patho exam 4 Flashcards
myelinated peripheral neurons have capacity for
regeneration
substance P transmitters are
specific neurotransmitters for Pain
prefrontal lobe function
function of frontal lobe is goal oriented behavior, short term or recall memory, thought, movement, decision making
Broca area function
motor speech
occipital lobe function
visual cortex
medulla oblongata
Connects the cardiovascular and respiratory systems- control reflex activities such as heart rate, breathing, and blood pressure coughing sneezing swallowing and vomitting
Anatomy of the tentorium cerebelli
separates the cerebellum below from the cerebral structures above
Function of CN 1
Olfactory nerve sense of smell
function of arachnoid villi
absorption of CSF- Directs CSF outflow into the blood but preventing blood flow into the subarachnoid space
astrocyte cells
closely supported to the blood brain barrier
vagus nerve stimulates
cardiac muscle and GI lining
alpha 1 receptors
when a patient starts a new medication, alpha 1 receptors are activated and they vasodilate- they lower bp, slow gastric motility, widen eyes
How much cardiac output does the brain need
20% or 800-1000 ml
cerebral aneurysm is located in
the brain around the circle of willis
if pituitary gland was removed which hormone will decrease
ADH . TSH, FSH
In osteoporosis if the provider prescribed calcitonin it will
inhibit calcium reabsorption to the bones
insulin is regulated by
serum glucose levels in the blood
cause of type 1 DM
pancreas is no longer producing insulin from destruction of pancreas cells- needs insulin
Cause of type 2 DM
genetics-environmental interaction
Complications of Type 1 DM with Elevated glucose and patient in DKA
will have insulin deficiency, lipid metabolism, ketones in urine (ketonuria)
complications of DM
Hyper and hypoglycemia
3 Ps of DM pt
polyuria polydipsia polyphagia
