Italian anatomist and pathologist, physician and surgeon (1666-1723), perhaps best known for the Valsalva maneuver.
Valsalva described and depicted even the smallest muscles and nerves of the ear, subdividing the ear into its internal, middle, and external parts, and he showed an original method of inflating the middle ear (Valsalva maneuver). Valsalva coined the term Eustachian tube, one of the earliest eponyms known. Valsalva noted that motor paralysis is on the opposite side to the cerebral lesion both in stroke and in cases of cranial injury.
As a surgeon Valsalva anticipated the importance of nephrectomy, and did work in ophthalmology, rhinology, and tumor surgery. He invented surgical instruments that were of great use.
Valsalva also has a place in the history of psychiatry for having been among the first to call for, and in part to implement, humanitarian treatment of the insane. He considered madness to be analogous to organic disease.
- Valve, aortic
One of the four valves in the heart, this valve is situated at exit of the left ventricle of the heart where the aorta (the largest of all arteries) begins. The aortic valve lets blood from the left ventricle be pumped up (ejected) into the aorta but prevents blood once it is in the aorta […]
- Valve, bicuspid
One of the four valves of the heart, this one is situated between the left atrium and the left ventricle. It permits blood to flow one way only, from the atrium into the ventricle. The valve is more commonly called the mitral valve because its two flaps (cusps) makes it look like a bishop’s miter […]
- Valve, mitral
from the left atrium into the left ventricle. The mitral valve has two flaps (cusps) and so is called “mitral” because it looks like a bishop’s miter or headdress. Also known as the bicuspid valve.
- Valve, pulmonary
One of the four valves in the heart, the pulmonary valve stands at the opening from the right ventricle in the pulmonary artery trunk. It lets blood head in the right direction (toward the lungs) and keeps it from sloshing back from the pulmonary artery into the heart.
- Valve, tricuspid
One of the four heart valves, the tricuspid valve is the first one that blood encounters as it enters the heart. The tricuspid valve is situated between the right atrium and right ventricle and allows blood to flow only from the atrium into the ventricle.
