The spelling of the word "arteria hyaloidea" may seem intimidating, but taking a closer look at its phonetic transcription, [ɑrˈtɛriə ˌhaɪəloʊˈɪdiə], can make it much easier to pronounce. "Arteria" is pronounced as "ar-TEER-ee-uh" and "hyaloidea" is pronounced as "high-uh-loy-DEE-uh". This term refers to the embryonic artery that nourishes the lens of the eye in developing embryos. While it may be a tongue twister, understanding the phonetics behind the spelling of "arteria hyaloidea" can make it less daunting to say.
The term "arteria hyaloidea" refers to a blood vessel found in the eye during embryonic development. It is also commonly known as the hyaloid artery. The hyaloid artery is a temporary fetal structure that plays a vital role in supplying blood and nutrients to the developing eye.
During early stages of embryonic eye development, the hyaloid artery emerges from the optic disc, extending towards the lens. It helps nourish the developing lens as well as other structures within the eye, such as the vitreous humor and the retina. However, as the eye continues to mature, the hyaloid artery starts to regress and eventually disappears completely in most cases.
The disappearance of the hyaloid artery is a normal process, and its absence is crucial for optimal vision. After the hyaloid artery regresses, remnants of its original path can be observed as the hyaloid canal or Cloquet's canal, which can still be visible in some individuals.
Understanding the development and regression of the arteria hyaloidea is important not only for embryologists and anatomists but also for ophthalmologists. The presence of remnants or abnormalities associated with the hyaloid artery in adulthood can lead to various eye conditions like persistent hyperplastic primary vitreous (PHPV) or retrolental fibroplasia.
In summary, the arteria hyaloidea is a significant vascular structure in early eye development that supplies nutrients and blood to the developing eye. Its regression is necessary for normal visual function, and its remnants can be observed as the hyaloid canal.
A branch of the a. centralis retinae which runs through the hyaloid canal of the vitreous body in the fetus; it disappears in the last month of intrauterine life.

The term "arteria hyaloidea" is made up of two Latin words: "arteria" and "hyaloidea".
1. Arteria: The word "arteria" is derived from the Latin word "arteria", which means "artery" in English. It stems from the Greek word "ἀρτηρία" (artería), meaning "windpipe" or "artery". The Greek term itself is believed to have originated from the word "ἀείρειν" (aeírein), which means "to raise" or "to raise up". The term "arteria" was initially used to refer to the air-carrying windpipe, but later, in ancient medical usage, it was extended to describe the vessels that carry blood away from the heart.
