• Algospasm — A painful muscle spasm; an involuntary, sudden, violent, and persistent contraction of a muscle or muscle group, accompanied by an intense sensation of acute pain. In clinical practice, it describes severe nociceptive episodes associated with cramps or visceral colic.
• Anoxemia — An extreme pathological condition characterized by a drastic decrease or complete absence of oxygen in arterial blood. In clinical pathophysiology, this structural phenomenon represents a severe form of hypoxemia, occurring as a result of mechanical asphyxia, acute respiratory failure, toxic gas poisoning, or major circulatory dysfunctions, placing cellular metabolism and the viability of vital organs, especially the brain, in imminent danger.
• Anoxia — A grave pathological condition characterized by the complete absence of oxygen in the body's tissues, representing the terminal and most severe form of hypoxia. In clinical pathophysiology, this major structural deficiency blocks cellular respiration and energy production, causing rapid necrosis and irreversible damage in highly sensitive organs, such as the cerebral cortex and myocardium.
• Autopepsia — Spontaneous self-digestion of an organ's tissues (especially the gastric mucosa or the pancreas) caused by its own enzymatic secretions or digestive juices, due to pathological disruptions of cellular protective mechanisms or following post-mortem necrosis. In gastroenterology, this destructive structural phenomenon forms the basis for the onset of perforating peptic ulcers or acute necrotizing-hemorrhagic pancreatitis.
