Which body system is responsible Parasympathetic nervous system
for conserving energy and body
resources
which system responds to stress by Sympathetic nervous system (SNS)
preparing the body to defend itself
how is blood flow redistributed by blood flow to the muscles is increased while
the sympathetic nervous system blood flow to GI and integumentary is decreased
(SNS)
how are primary brain injuries focal or diffuse (aka multifocal)
classified
, focal brain injuries specific, grossly observable brain lesions that
occur in a precise location
Epidural and subdural hemorrhages
diffuse brain injuries include brain injury due to hypoxia, meningitis,
encephalitis, and damage to blood vessels
The brain is confined in a limited space so
increased pressure can cause collateral
dysfunction: Diabetes Insipidus (ADH not
secreted thus polyuria)
autonomic hyperreflexia characterized by paroxysmal HTN (up to 300
mmHg systolic), a pounding headache, blurred
vision, sweating above the level of the lesion with
flushing of the skin, nasal congestion, nausea,
piloerection caused by pilomotor spasm, and
bradycardia (30-40 beats/min)
location of lesions in cases of individual most likely to be affected have lesions
autonomic hyperreflexia at the T5-T6 level or above
sequence of events that lead to bradycardia (30-40bpm) is a sx of hyperreflexia
hyperreflexia induced bradycardia Stimulation of the carotid sinus -->vagus nerve --
>sinoatrial (SA) node. The intact ANS reflexively
responds with an arteriolar spasm that increases
blood pressure. Baroreceptors in the cerebral
vessels, the carotid sinus, and the aorta sense the
HTN and stimulate the PNS. The heart rate
decreases, but the visceral and peripheral vessels
do not dilate because efferent impulses cannot
pass through the cord
Alzheimer's disease leading cause of dementia and one of the most
common causes of severe cognitive dysfunction
in older adults
