Aroused
Aroused
Aroused (/əˈraʊzd/) is a term used in various fields of medicine, particularly in psychology and neurology, to describe a state of heightened physiological activity.
Etymology
The term "aroused" originates from the Old English word "arisan," which means "to get up, rise." In the medical context, it has been used since the late 19th century to describe the state of being awake or reactive to stimuli.
Definition
In a medical context, being aroused refers to the state of being awake and responsive to stimuli. It involves a range of physiological changes, such as increased heart rate, blood pressure, and brain activity. Arousal is regulated by the reticular activating system, a network of neurons located in the brainstem.
