Syphilis of the central nervous system is characterized by the Argyll Robertson pupil, which constricts with accommodation but not in response to light. This condition frequently leads to thoracic aortic aneurysm.
9 All of the following descriptions of Type I diabetes mellitus are accurate EXCEPT for: EXP A lack of insulin comes from Type 1 diabetes mellitus, which is brought on by the death of beta islet cells.

Increases in insulin levels prevent the pancreatic -cells from releasing glucagon. This paracrine function is a fundamental part of how insulin regulates glucagon's activation of adipose tissue lipolysis and hepatic gluconeogenesis.
The histamine receptor antagonist cimetidine actively lowers stomach HCl levels. As a result, peptic ulcers are routinely treated with it.
Myocarditis, or myocardial inflammation, commonly manifests as conjunctivitis, urethral discharge, and arthralgia.
Aortic regurgitation is linked to a Quincke pulse, which alternately causes the skin or nail beds to flush and turn pale. The waterhammer pulse and pulsus bisferiens are additional distinguishing characteristics of the peripheral pulse in aortic regurgitation.
