When the fetus has developed enough to survive outside the uterus, the cervix dilates, and contractions of the uterus propel it through the birth canal (the vagina), where it becomes a newborn. The breasts are not part of the reproductive system, but mammary glands were essential to nourishing infants until the modern advent of infant formula .
The human vagina is an elastic, muscular canal that extends from the vulva to the cervix. [9] [10] The opening of the vagina lies in the urogenital triangle. The urogenital triangle is the front triangle of the perineum and also consists of the urethral opening and associated parts of the external genitalia. [11]
Structures opening in the vulval vestibule are the urethra (urinary meatus), vagina, Bartholin's glands, and Skene's glands. [1]The external urethral orifice is placed about 25–30 millimetres (1–1.2 in) [2] behind the clitoris and immediately in front of that of the vagina; it usually assumes the form of a short, sagittal cleft with slightly raised margins.
There may be associated duplications of the more cranial parts of the Müllerian derivatives, a double cervix, and either a uterine septum or uterus didelphys (double uterus). [1] [2] A transverse septum forms during embryogenesis when the Müllerian ducts do not fuse to the urogenital sinus. A complete transverse septum can occur across the ...
Uterus didelphys (from Ancient Greek di- 'two' and delphus 'womb'; sometimes also uterus didelphis) represents a uterine malformation where the uterus is present as a paired organ when the embryogenetic fusion of the Müllerian ducts fails to occur. As a result, there is a double uterus with two separate cervices, and possibly a double vagina ...
Seattle Municipal Light and Power Plant, also known as Cedar Falls Historic District, is a public hydroelectric plant near North Bend, Washington operated by Seattle City Light. The plant on the Cedar River was the first publicly-owned electrical generating plant for Seattle and one of the earliest in the country for a municipality of its size.
The cervix (pl.: cervices) or cervix uteri is a dynamic fibromuscular sexual organ of the female reproductive system that connects the vagina with the uterine cavity. [1] The human female cervix has been documented anatomically since at least the time of Hippocrates , over 2,000 years ago.
The Sioux Falls Light and Power Hydro Electric Plant, formerly the Northern States Power Building, is a historic building in Falls Park in Sioux Falls, South Dakota. Originally built as a hydroelectric power plant on the Big Sioux River, it now houses the Falls Overlook Cafe. It was listed on the National Register of Historic Places in 1993. [2]
