Verheyen stars (lat. stellulae verheyenii) - folds of the mucous membrane of the bladder. Named after the Flemish anatomist Philip Verheyen (1648–1710).
Fereen's stars are small outgrowths of the mucous membrane, located mainly in the neck of the bladder. The number of these outgrowths varies from 5 to 12. Their size is from 0.5 to 1.5 mm. Fereen stars have the appearance of star-shaped folds, which is where they get their name.
Functionally, the asterisks ensure the resistance of the mucous membrane of the bladder to stretching when it is filled. In addition, they prevent the backflow of urine from the bladder into the ureters.
With some pathologies of phereiene, the asterisks may increase in size and number. This can lead to disruption of the outflow of urine from the bladder and the development of bladder dysfunction.
Fereyena star or Stellulae verheyenia (stellula verheyeni) is a genus of plants of the Aster family or Asteraceae, it is also called Capsicum polycarp. Also sometimes this genus is called seed or rock star
The origin of the Latin name Stellulae is not known with certainty. Perhaps it is related to the shape of the seeds (thorn). Stella is a “star”. Another name is Fereyen starry. Ferae is a translation of the Greek “melliferous.”
