"Sphygmography" Natural Recordings by Native Speakers
Sphygmography is a medical imaging technique used to record the pattern of blood flow and pressure through blood vessels, especially the arteries. It involves tracing the pulse pattern on a finger or earlobe with a pencil or a special device. This method was used in the early 20th century to diagnose diseases such as syphilis and athero-arteriosclerosis (hardening of the arteries).
In botany, a sphragis is a specific type of crown or appendage found on certain orchid flowers, particularly on those belonging to the genus Ophrys. It's a sterile, compact growth that arises from the base of the flower's column or column foot and resembles a berry or an ovary, although it's not actually a part of a seed. The sphragis serves as a mechanism to enhance pollination, providing a surface for pollinators, such as bees, to land on and go about their activity, sometimes resulting in the collection and transfer of pollen. In some cases, the term "sphragis" can also refer to the botanical term for a seal or sign, a mark indicating a specific property or character of a plant, such as its fragrance or a certain colour.
Sphingosine<em></em><br><br>1. a colourless oily base, C18H35NO8P, that forms in the decomposition of sphingomyelin, found in the brain and other tissues of animals, and also used as an emulsifying agent, also called<br> iktischer phosphate, sphingoside.
A sphygmogram is a graph or record of the pulsation or blood pressure of the arteries. It is a medical term used to describe a visual representation of the heartbeat, typically recorded using an instrument called a sphygmograph. This graph can provide valuable information about the patient's cardiovascular health, including the strength and rhythm of the heartbeat, as well as any potential abnormalities.
A sphygmometer is a medical device used to measure the blood pressure in a person's vessels, usually in the arm or finger. It is a simple, non-invasive device that inflates a cuff around the upper arm to constrict the blood vessels, then slowly deflates while listening with a stethoscope to the sounds of the heartbeat, known as Korotkoff sounds, which change as the blood pressure decreases.<br><br>A sphygmometer can provide a reading of both systolic pressure (the pressure in the arteries when the heart beats) and diastolic pressure (the pressure in the arteries between beats).
