arteria hyaloidea (medicine)


arteria hyaloidea -->
hyaloid artery
<anatomy, artery> The terminal branch of the primitive ophthalmic artery, which forms in the embryo an extensive ramification in the primary vitreous and a vascular tunic around the lens; by 81/2 months, these vessels have atrophied almost completely, but a few persistent remnants are evident entoptically as muscae volitantes.

B-Main - Motor Sports (gambling)


A second-chance race sometimes seen at an event that uses heat races to determine qualifying and starting positions for the feature. The B-main includes all cars who failed to finish in a qualifying position in their respective heat races, and a certain number of additional qualifying positions are available to the B-main' s top finishers. Also called a "last chance" or "B-heat" race. Some very large events might use a third level of heat race for cars that fail to qualify in the B-main race(s), and this would be referred to as the C-main. Compare to consolation race.
