"Parasternal" Natural Recordings by Native Speakers
The term "parasternal" refers to the region of the thorax (chest) situated beside the sternum (breastbone), typically in the area of the second and third intercostal spaces. In medical contexts, this area is often used as a reference point for examining the heart and lungs, particularly in cardiothoracic medicine. In anatomical terms, the parasternal region includes the areas between the second and third ribs and the edges of the sternum. This region is also the site of insertion for the parasternal intercostal arteries, which supply oxygenated blood to the heart.
Parasympatholytics are medications or substances that inhibit or block the effects of the parasympathetic nervous system, which is a branch of the autonomic nervous system responsible for promoting relaxation, reducing stress, and conserving energy.
