diffuse brain injuries - ANSWER 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 - ANSWER affected at the t5-t6 level or above; characterized by
paroxysmal HTN (up to 300 mmHg systolic), a pounding headache, blurred vision, sweating

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
