When this happens the individuals develop structures that are derived from the paramesonephric duct, and also structures that are derived from the mesonephric duct. A male that has persistent Müllerian duct syndrome may have an upper vagina, uterus, and uterine tubes as well as ductus deferens along with male external genitalia. The female ...
Müllerian duct anomalies are those structural anomalies caused by errors in Müllerian duct development as an embryo forms. Factors contributing to them include genetics and maternal exposure to substances that interfere with fetal development. [1] [2] Genetic causes of Müllerian duct anomalies are complicated and uncommon.
Persistent Müllerian duct syndrome (PMDS) is the presence of Müllerian duct derivatives (fallopian tubes, uterus, and/or the upper part of the vagina) [1] in what would be considered a genetically and otherwise physically normal male. [2]
Historically, the cause of nasopalatine duct cysts has been somewhat of an enigma. Although it was originally postulated that the cyst formed from trapped epithelial cells during embryonic fusion of the palatal bones, [3] it is now thought that it forms from oronasal ducts present within the incisive canals. [4] [5]
Müllerian agenesis, also known as Müllerian aplasia, vaginal agenesis, or Mayer–Rokitansky–Küster–Hauser syndrome (MRKH syndrome), is a congenital malformation characterized by a failure of the Müllerian ducts to develop, resulting in a missing uterus and variable degrees of vaginal hypoplasia of its upper portion.
Sinus tubercle (also known as sinual tubercle [1] or Müllerian eminence) is the proliferation of endoderm induced by the paramesonephric ducts.It is located in the developing fetus between the orifices of the mesonephric ducts on the urogenital sinus. [1]
The appendix testis (or hydatid of Morgagni) is a vestigial remnant of the Müllerian duct, present on the upper pole of the testis and attached to the tunica vaginalis. It is present about 90% of the time. [citation needed]
Müllerian may refer to: . Müllerian mimicry, a type of mimicry or convergence named after Fritz Müller; Müllerian ducts, which enter the cloaca of an embryo (named after Johannes Peter Müller)
